摘要

评价了阳离子聚丙烯酰胺及其疏水衍生物在细胞培养液中细胞生物量分离阶段的应用效率。通过絮凝和浮选从混合培养液中获得的油降解微生物细胞保留了其在非无菌条件下进一步用于处理油污染土壤的活力。一种新型的油氧化制剂的应用使污染土壤中总石油烃含量降低了40%。

Modeling a new form of oil-oxidizing preparations in the form of cell agglomerates of mixed cultures of microorganisms stabilized by polyelectrolytes and salts of higher fatty acids

he efficiency of application of cationic polyacrylamide and its hydrophobized derivative at the stage of cell biomass separation from the cell cultures fluid is estimated. Cells of oil-degrading microorganisms obtained from mixed culture fluid by flocculation and flotation retain their viability for further use in the treatment of oil-contaminated soils under non-sterile conditions. The application of a new form of oil-oxidizing preparation resulted in a 40 % reduction of total petroleum hydrocarbon content in the contaminated soil.
