[Influence of clay on microorganisms conservation. I. Ultrastructural study of the biodegradation of Beauveria bassiana (Bals). Vuill. (entomopathogenous hyphomycete) in soil (author's transl)].

Blastospores of B. bassiana enclosed in fine mesh bags were submitted to soil microflora. Clay minerals coating fungal spores protected from by decreasing bacterial activity. The role of amoeba in biodegradation of fungi is also considered.
