dc.description.abstract | Solid-state fermentation (SSF) is a fermentation process where different agro-industrial
residues have been used as substrates to maximize their utilizations and to address the waste
disposal issues. Bacillus sp. strain has been studied for its ability to produce different enzymes
by SSF of agro-industrial residues. Soybean meal (SBM) is a co-product after solvent
extraction process in dietary oil production and high quality source of protein.
Herein, SBM was assessed for the production of hydrolytic enzymes through SSF with
Bacillus sp. strain for 8 days at 30 °C. Highest obtained yields of producing proteases,
cellulases, α-amylases and pectinases were 56.4, 0.89, 0.95 and 1.07 U g-1, respectively. The
enzymes produced were very different in biochemical characteristics, including activities at
specific temperatures and a wide range of pH values. The highest activity proteases,
cellulases, α-amylases exhibited at higher temperatures, 50 °C suggesting the high potential of
these enzymes for industrial application involving elevated conditions. Fermented soybean
meal (FSBM) was examined in terms of total phenol content (TPC), scavenging DPPH and
ABTS radical abilities. Scavenging DPPH and ABTS abilities of FSBM were all stronger than
that of SBM. The radical scavenging ability increased by fermentation in accordance with the
increase in TPC content. TPC increase from 1.12 to 3.12 mgGAE/g soybean meal after three days
of fermentation was observed. The high hydrolytic enzyme activity and stability established
plus the low cost of the substrate make this solid-state process a promising tool for
biotechnological industry. | sr |
