礁周辺が死の海と化する危険性をもはらんでいる。2. Description of the Related Art At present, environmental destruction is progressing on a global scale due to various causes, and water systems are no exception. For example, in sea areas, fish and shellfish are drastically reduced due to pollution in coastal areas, especially in harbor areas, and eutrophication is progressing in rivers and lakes. In order to solve this problem, artificial fish reefs are currently being put into the sea.However, since the artificial fish reefs are mostly made of concrete, if they are left in seawater, calcium hydroxide ( Alkaline components in concrete such as Ca (OH) 2 ) elute and the pH in the vicinity rises, making it difficult for algae to attach to the artificial reef, making it difficult to breed fish and shellfish that feed on algae. There is a risk that the area around the artificial fish reef will become a dead sea.

進行する大きな要因となっている。Also, in rivers and lakes where concrete revetments and river beds are provided, the alkaline components in the concrete are eluted into the water and algae and other aquatic plants are concerned, as in the case of the above-mentioned sea area. It is difficult for the algae to adhere to revetments and riverbeds, and the purification action such as absorption of heavy metals by such algae is hindered. As a result, pollution of water quality of rivers, lakebeds, etc. is a major factor.

Has been done. However, in this method, since the surface of the concrete is not biologically activated, there is a drawback that the growth of algae is slow. In addition, a method of mixing natural shellfish powder, oyster shell powder and the like into a resin or the like for coating has been attempted for the purpose of biological activation, but it has not been sufficiently successful.

重量部に対して１〜1000重量部である。The carrier is preferably added in an amount of 1 to 1000 parts by weight, preferably 10 to 300 parts by weight, per 100 parts by weight of the binder to be described later. When the amount of the carrier added is less than this, the growth density of the phototrophic bacteria is low, and conversely, when it is too large, the strength of the coating film formed by the coating composition of the present invention decreases.
It should be noted that by merely including the carrier and phototrophic bacteria in the paint, almost no activity of phototrophic bacteria is observed, and it is difficult for the desired effect to be exhibited by adding phototrophic bacteria as a water purification component. Therefore, it is necessary to include the nutrient component of the phototrophic bacterium in the coating material for improving aquatic environment of the present invention.
Examples of such nutritional components include known components that are usually added to the culture medium when culturing phototrophic bacteria, such as lower fatty acids, but the kuroboku which is abundant in volcanic ash soil areas can be used as the nutrient. It is possible and preferable to be used as a component and an environment where phototrophic bacteria grow. The amount of the nutritional component added to the coating for improving the aquatic environment of the present invention is appropriately determined according to the type of the nutritional component used. For example, when using Kuroboku, the binder 100 described below is used.
It is 1 to 1000 parts by weight with respect to parts by weight.

In order to achieve early settlement, the spores and / or quiescent cell bodies of algae or aquatic plants can be added in advance. The type of algae or aquatic plant used here is selected according to the environment in which the artificial construct is used, for example, seawater or fresh water, and is not particularly limited as long as it is.

Such spores and / or quiescent cell bodies can be collected from natural sources and used as commercial products. The aquatic environment-improving coating material of the present invention can be prepared by blending the above-mentioned phototrophic bacterium, carrier, and nutrient component, and, if necessary, spores and the like with a binder.

It is necessary to separate the nutrient bacteria and the other components in advance, and it is preferable to mix them during coating. Also, spores, etc. need to be stored in a state suitable for their survival, so, for example, in an acrylic emulsion.
It is not preferable to coexist for 24 hours or more, and it is preferable to mix them at the time of coating, like the above-mentioned phototrophic bacteria.

The material may be applied once, but it is preferably applied two or three times in order to accelerate the drying time and increase the coating film strength. That is, if a thick coating is applied at one time, it tends to be difficult to dry and the formed film tends to become brittle. On the other hand, if it is too thin, the alkali leaching prevention effect of the concrete and the biological activation of the surface tend to be poor. The thickness of the subsequent coating film is 30
It is preferably about 500 to 500 μm, more preferably about 50 to 150 μm. In addition, it is preferable to wash and dry the surface of the material before coating in order to prevent coating defects such as peeling. Incidentally, such washing and drying can be performed by a generally known method.

るためとも考えられる。The inclusion of phototrophic bacteria as a water purification component promotes the growth of algae or aquatic plants on materials because vitamin B 12 , amino acids and nucleic acids secreted by the phototrophic bacteria themselves. It is believed that this is because the growth of such algae has a very favorable effect. Further, it is also considered that the pH-lowering action of phototrophic bacteria generally has the action of neutralizing the alkaline component leached from the concrete material.
