had a high degree of pollution, the influence of the interaction by which the added
microbial pesticide acted as competition with a settled microorganism and
decreased. Or it was supposed that the physicochemical-like factor, which is the
water quality, as well as the interaction between the organisms in the behavior of
microbial pesticides is closely related.
7.12.5 Verticillium lecanii F126-12-3M
Verticillium lecanii F126-12-3M, as a fungal pesticide, was added at one and ten
times the abundance of indigenous bacteria in the microcosm, and its influence on
the structure and function of the ecosystem was examined. Verticillium lecanii F12612-3M slowly decreased at 1- or 10-times inoculation concentrations in viable
counts using the selective media method after microcosm inoculation, and the
abundance of small microorganisms in the microcosm increased. Verticillium lecanii
F126-12-3M has been shown to be a suitable food source for only Philodina
erythrophthalma and Aeolosoma hemprichi in the predator-prey interaction test,
which was considered to be dominated by these predatory actions. By comparison,
in N 30 , no significant difference was observed between the system with Verticillium
lecanii F126-12-3M added and the system without it (control system).
7.12.6 Metarhizium anisopliae M7
Metarhizium anisopliae M7, as a fungal pesticide, was added at one and ten times
the abundance of indigenous bacteria in the microcosm, and its influence on the
structure and function of the ecosystem was examined. Metarhizium anisopliae M7
slowly decreased at 1- or 10-times inoculation concentrations in viable counts using
the selective media method after microcosm inoculation, and the abundance of
microorganisms in the microcosm increased. Metarhizium anisopliae M7 has been
shown to be a suitable food source for constituent heterotrophic groups such as
metazoan Philodina erythrophthalma and Aeolosoma hemprichi. By comparison, in
N 30 , no significant difference was observed between the system with Metarhizium
anisopliae M7 added and the system without it (control system).
7.13 Genetically Modified Bacteria
With the advancement of genetic engineering, the release of useful new microorganisms (e.g., genetically modified bacteria, genetically engineered microorganisms) to the environment has been investigated in various fields. From the
viewpoint of environmental protection, their safe use should be confirmed before
regular environmental release. It is essential to elucidate the behavior of GEMs in
