Phosphatase production by microorganisms isolated from diverse types of soils.

Qualitative and quantitative nature of phosphatases produced by various fungal, bacterial, and actinomycetes isolates from diverse soils was examined. Soil fungi, particularly those belonging to the genera Aspergillus and Penicillium, were found to be most effective in producing phosphatases intra- and extracellularly. None of the 16 bacterial isolates produced acid phosphatase, but most of them did produce neutral phosphatase. Actinomycetes produced only negligible quantities of phosphatases.
