Abstract

Twelve fungal cultures isolated from Indian desert soils belonging toAspergillus, Penicillium, Acrophialophora andAlternaria were found to produce both acid and alkaline phosphatases in liquid medium, their amounts varying from culture to culture. Maximum production of these enzymes was observed withA. niger. In general, acid phosphatase activity was much higher as compared to alkaline phosphatase. The optimum incubation period for the production of these enzymes was found to be 14 d and thereafter it started declining. There was a significant and positive correlation between biomass production and acid phosphatase activity but not with alkaline phosphatase.
