| bolites was investigated in the present study. Moreover, to protect actinomycete against actinophage attack immobilization in alginate beads was used. Presence of actinophages in the liquid culture of actinomcete (AC2) free cells, markedly reduced the fresh and dry weight of its mycelium as compared to the free cells culture in absence of actinophages. Whereas, the highest fresh and dry weight of mycelium were recorded in alginate immobilized culture. In case of actinomycete immobilized cells, presence of actinophages had no marked effect on the fresh and dry weight of mycelium. The highest amount of metabolites were produced by immobilized actinomycete as compared to that produced by the free cells. Presence of actinophages had no marked effect on the amount of metabolites produced by immobilized cells. Using gas chromatography–mass spectrometry (GC-MS) analysis, five chemical compounds were detected in metabolites of actinomycete isolate (AC2). | ||
