Abstract

Two Bacillus strains capable of emulsifying immiscible organophosphorus pesticides were isolated by enrichment methods. The emulsifying factor produced by Bacillus strain FE-2 has a high molecular weight, is Iysozyme sensitive and thermostable, and can be precipitated with trichloroacetic acid or ammonium sulfate; it may be a glycolipopeptide. It is specific for immiscible organophosphorus pesticides and is secreted during growth in the presence of such pesticides.

摘要

采用富集培养的方法,从土壤中分离到两株能有效乳化不混溶有机磷农药的芽孢杆菌。FE-2 菌株产生的乳化因子分子量较大,对溶菌酶敏感,热稳定性高,可以用三氯乙酸或硫酸铵沉淀,可能是一种糖脂肽。它对不混溶有机磷农药具有特异性,在有这类农药存在的条件下生长时分泌产生。
