Assessment of six oil seed cakes as substrate for production
of protease by solid state fermentation by Aspergillus sp.
isolated from leather. The agro-industrial by product (oilseed
cakes) namely soybean, groundnut, sesame, linseed, mustard
and cotton were evaluated as inducer for production of
protease using solid state fermentation (SSF) in the
presence of defined diluent as moistening agent was
investigated. Enzyme synthesis was maximum (107.66 U/ml)
when soybean oil seed cakes was used as substrate followed
by sesame oilseed cake (76.04 U/ml). Protease production
using such low cost substrate provide economical efficacy.
Key words:
Protease, Aspergillus, substrate, moistening agent,
fungi. |
