[The autoselection of neustonic forms of bacteria].

Self-breeding of neuston forms of Methylobacterium sp., Pseudomonas putida BC-2, Alcaligenes paradoxus BC-1, Bacillus thuringiensis var. israilensis bacteria as well as of a mixed culture of methylotrophs is shown possible. In spite of ability of hydrophobicity of the cell surface the suggested method of self-breeding may be used to perfect properties of larvicidal biopreparations, and bacterial preparations which intensify self-purification of water bodies.
