  Hereinafter, an embodiment of the present invention will be described.

  Various microorganisms exist in the oceans and lakes. For this reason, the collection and analysis of underwater microorganisms has been instrumental in investigating marine and lake environments. For example, it has been studied to predict the environmental change by investigating the distribution of microorganisms in water before and after the occurrence of a predetermined environmental change such as a red tide.

  FIG. 9 is a diagram illustrating an example of a conventional method for collecting underwater microorganisms. FIG. 9A shows a state where seawater is collected using the water sampling device 40. Conventionally, the seawater is collected by sinking the water sampler 40 at a predetermined point in the sea, and the collected seawater is filtered using a filter 41 as shown in FIG. Then, the underwater microorganisms remaining in the filter 41 are collected.

  By the way, the microorganisms in the water move along the tide. For example, cysts (cysts) β1 of underwater microorganisms contained in seabed mud rise in the tide and move to other sea areas. The vertical width (depth) and speed of the tidal current vary from day to day.

  For example, when the ebb and flow caused by ebb and tide are considered as one cycle, the depth, direction, and speed of the tidal current differ in each cycle. In monitoring that collects underwater microorganisms a plurality of times and compares the collected results to investigate the distribution state, the monitoring of the underwater microorganisms is continued for a certain period of time (for example, one cycle of ebb and flow) in a predetermined sea area. It is desirable to perform collection and smooth the collection result to reduce variations in collection conditions such as the depth, direction, and speed of the tidal current. However, in the collection of the underwater microorganisms using the water sampling device 40, since the underwater microorganisms are collected from the water immediately flowing into the water sampling device 40, the sampling conditions are different each time the sampling timing is changed, which is not suitable for monitoring. .

  <First embodiment>

  FIG. 1 is a diagram illustrating an example of an underwater microorganism collector 1 according to the first embodiment. The underwater microorganism collector 1 has a collector 11, a buoy 12, a rope 13, and an anchor 14.

  The collection tool 11 is a member that collects underwater microorganisms. The collection tool 11 has an adhering material for adhering microorganisms in water. Although the underwater microorganism collector 1 shown in FIG. 1 includes three collecting tools 11, the number of collecting tools is not limited to this. The underwater microorganism collector 1 includes one or a plurality of collectors 11.

  The adhering material is made of a material to which underwater microorganisms adhere. In one example, the attachment material comprises a porous material or a material in which fine fibers are entangled. The attachment material is, for example, polypropylene, polyurethane, polyethylene, polyamide, polycarbonate, acryl, cellulose mixed ester, or cellulose acetate. The adhering material causes the underwater microorganisms to adhere to the porous surface or to filter the water to attach the underwater microorganisms. The adhering material is, for example, carbon, and is adhered by absorbing microorganisms in water. In another example, the attachment material is a metal material. The attachment material is, for example, iron. The shape of the attachment material is not limited. The attachment material may be in the shape of a cube or a rectangular parallelepiped, or may be in the form of a sheet.

  The buoy 12 is a floating tool floating on the water surface, and holds the rope 13 so that the rope 13 connected to the anchor 14 extends downward from the water surface. The rope 13 is a member for installing the collection tool 11 underwater. When the underwater microorganism collecting apparatus 1 includes a plurality of collecting tools 11, the rope 13 sets the plurality of collecting tools 11 at different depths in the water. In addition, in the underwater microorganism collector 1 shown in FIG. 1, a plurality of collection tools 11 are held with respect to one rope 13, but when the underwater microorganism collection apparatus 1 includes a plurality of collection tools 11, each collection is performed. The tool 11 may be held by a plurality of different ropes 13.

  The collecting device 11 is held on the rope 13 at a predetermined interval (for example, at an interval of 5 m). The rope 13 is, for example, a bendable wire or the like, but may be a non-bendable pole or the like.

  The anchor 14 is a weight for keeping the underwater microorganism collector 1 at a predetermined point in the water, and the rope 13 is held by the anchor 14 substantially perpendicular to the water surface. If the rope 13 does not bend, the anchor 14 is not always necessary.

  When the underwater microorganism collecting device 1 includes a plurality of collecting devices 11, the underwater microorganism collecting device 1 may hold the collecting devices 11 at different positions on the same plane parallel to the horizontal plane. In that case, the rope 13 is held substantially horizontally with respect to the buoy 12. Thereby, it is possible to investigate the distribution state of the microorganisms in the water at different positions at the predetermined depth.

  FIG. 2 is a diagram illustrating an example of a configuration of the collection tool 11 according to the first embodiment. FIG. 2A is a diagram illustrating a configuration example of the collection tool 11. The collection tool 11 is composed of two attachment plates 110 forming a predetermined angle. The two attachment plates 110 are connected by a connecting portion 113, and the angle formed by the two attachment plates 110 is less than 180 degrees. The collection tool 11 is held by a rope 13 and is rotatable around the rope 13. Therefore, when the tidal current α hits the collection tool 11, the collection tool 11 rotates so that the connection portion 113 faces in the direction upstream of the tidal current α.

  When the rope 13 is held substantially horizontally, the rope 13 has a shaft extending in a direction substantially perpendicular to the horizontal plane, and the collection tool 11 is held so as to be rotatable along the circumferential direction of the shaft. Is done.

  The attachment plate 110 has a frame 111 and an attachment sheet 112. The frame 111 is a member that holds the adhesion sheet 112. The adhesion sheet 112 is handled as the above-mentioned adhesion material. In the present embodiment, the attachment sheet 112 is a sheet-shaped filter that filters seawater containing underwater microorganisms. The pore size (the size of the eyes) of the filter included in the attachment sheet 112 can be appropriately changed according to the size of the underwater microorganisms to be collected. Note that the attachment sheet 112 in the present embodiment is configured by stacking a plurality of filters having different pore sizes. Assuming that the portion formed by the two attachment plates 110 and having an angle of less than 180 degrees is the inside of the collection tool 11, the filters are stacked from the outside of the collection tool 11 in order of the pore size.

  FIG. 2B is a photograph showing an example of the collection tool 11. As shown in the figure, the collection device 11 is constituted by two attachment plates 110 forming an angle of less than 180 degrees.

  FIG. 3 is a diagram illustrating an example of the collection tool 11 according to the first embodiment as viewed from the buoy 12 direction. In this embodiment, the adhesion sheet 112 is bent and held with respect to the frame 111 (and the adhesion plate 110). Since underwater microorganisms enter into the bending of the adhesion sheet 112, more underwater microorganisms can be collected. The frame 111 may hold the adhesion sheet 112 without slack so that the frame 111 and the adhesion sheet 112 form the same plane.

  The two attachment plates 110 form an angle θ of less than 180 degrees. Each θ is, for example, 90 degrees. By appropriately adjusting the angle θ depending on the sea area or the like, it is possible to adjust the adhesion amount of the target underwater microorganisms or to prevent dust from adhering to the adhesion sheet 112.

  FIG. 4 is a diagram for explaining an outline of collection using the underwater microorganism collector 1 according to the first embodiment. The ebb tide α1 flows from left to right as shown in FIG. When the ebbing tide α hits the collecting tool 11, the collecting tool 11 rotates along the circumferential direction of the rope 13 such that the connecting portion 113 faces the upstream direction (leftward in FIG. 4A) of the ebbing α1. .

  In the collection of underwater microorganisms using the conventional water sampler 40, since the water sampler 40 is submerged, seawater is put into the water sampler 40, and the water is collected by raising the water, the water sampler is collected in a short time. Underwater microorganisms contained in seawater flowing into the forty were collected. Therefore, the microorganism group β2 existing upstream of the ebb tide α1 could not be collected. In the present embodiment, the underwater microorganism collector 1 is installed in the water continuously for a predetermined time in order to reduce variations in the collection conditions such as the depth, direction, and speed of the tide. Therefore, microorganisms in the water flowing along the tidal movement area γ can be collected. Therefore, the microorganism group β2 existing upstream of the ebb tide α1 is collected by the collection tool 11 which is continuously installed for a certain period of time.

  The time for installing the underwater microorganism collector 1 is, for example, 1 to 24 hours. In addition, for example, the time during which the underwater microorganism collector 1 is installed may be set based on a cycle generated by ebb and tide at the collection point. In this case, the predetermined time is, for example, the duration of a cycle including one ebb and one ebb. In addition, as long-term collection, for example, it may be installed for one week.

  The same applies to the rising tide α2 flowing from right to left in FIG. When the rising tide α2 hits the collection tool 11, the collection tool 11 rotates along the circumferential direction of the rope 13 so that the connecting portion 113 faces the upstream direction (the right direction in FIG. 4B) of the rising tide α2. The microorganism group β2 existing upstream of the rising tide α2 can also be collected by installing the underwater microorganism collection device 1 continuously for a certain period of time.

  In the underwater microorganism collector 1 according to the present embodiment, the influence of a temporary change in the situation is reduced by continuously installing the underwater microorganism collector 1 in the water for a certain period of time to obtain a smoother collection result. be able to. In addition, since the collection device 11 is installed at different depths in the water, it is possible to recognize the moving state in the depth direction of the underwater microorganisms that spring from the seabed mud δ along the tide. Therefore, more useful information can be obtained in monitoring the moving underwater microorganisms.

  FIG. 5 is a diagram illustrating an example of a process after collecting underwater microorganisms. First, the attachment sheet 112 is removed from the collection tool 11 (first step).

  Next, the microorganisms 31 are separated from the adhesion sheet 112 (second step).

  Next, DNA β3 is extracted from the microorganism 31 (third step).

  Next, the base sequence of the extracted DNA β3 is read using the DNA sequencer 33 (fourth step). Then, the read base sequence is analyzed and stored as data.

<Example of experiment>

  FIG. 6 is a table showing the extraction amount of DNA collected by the collection device 11 in the first embodiment. In this experimental example, one collecting tool 11 (the collecting tool 11 shown in the photograph of FIG. 2 (B)) was held by the rope 13, and the collecting tool 11 was sunk at a depth of 2 m in various places shown in FIG. 6. The filter constituting the adhesion sheet 112 had a diameter of 47 mm, and the pore size of the filter was 0.2 μm, 0.4 μm, or 0.45 μm, and DNA was extracted by the procedure shown in FIG. As shown in FIG. 6, DNA was extracted, and it was found that underwater microorganisms could be collected using the collection tool 11 in the first embodiment.

<Modification>

  FIG. 7 is a diagram illustrating a modified example of the underwater microorganism collector 1 according to the first embodiment. FIG. 7A is a photograph showing a modification of the collection device 11. The collection tool 11 in this modification includes a main body portion having an adhesion sheet 112 as an adhesion material therein, and a direction adjusting plate for guiding the main body portion to be directed in the upstream direction. In this drawing, the direction adjusting plate has a substantially triangular shape, and is configured such that the width gradually increases from the connecting portion connected to the main body portion to the other end facing the connecting portion. The shape of the direction adjusting plate is not limited to this. When the collecting tool 11 is installed in water, the water flow hits the side surface of the direction adjusting plate, so that the main body portion faces the upstream direction of the water flow.

  FIG. 7B shows a configuration example of the underwater microorganism collector 1. The underwater microorganism collecting device 1 may be provided with one collecting tool 11 in this modified example, or may be provided with a plurality of collecting tools.
