Evaluation of Ca-Independent a-Amylase Production by Bacillus sp. KR-8104 in Submerged and Solid State Fermentation Systems
This study investigates the production of crude Ca-independent and low pH active α-amylase by Bacillussp. KR-8104 in submerged fermentation (SmF) and solid-state fermentation (SSF) systems. Differentparameters were evaluated in each system using “one factor at a time” approach to improve the production ofenzyme. The results showed that in the SmF the maximum enzyme production ...
متن کاملThermostable saccharogenic amylase produced under submerged fermentation by filamentous fungus Penicillium purpurogenum
The effect of several nutritional and environmental parameters on Penicillium purpurogenum growth and sacharogenic amylase production was analyzed. High enzyme levels (68.2 U mg(-1)) were obtained with Khanna medium at initial pH 6.0, incubated at 30°C for 144 hours. The optimum pH and temperature activities were 5.0 and 65°C, respectively. The enzyme presented a half-life (t50) of 60 min, at 6...
متن کاملProduction of Pectate Lyase by Penicillium viridicatum RFC3 in Solid-State and Submerged Fermentation
Pectate lyase (PL) was produced by the filamentous fungus Penicillium viridicatum RFC3 in solid-state cultures of a mixture of orange bagasse and wheat bran (1 : 1 w/w), or orange bagasse, wheat bran and sugarcane bagasse (1 : 1 : 0.5 w/w), and in a submerged liquid culture with orange bagasse and wheat bran (3%) as the carbon source. PL production was highest (1,500 U mL(-1) or 300 Ug(-1) of s...
متن کاملMetabolomic and Transcriptomic Comparison of Solid-State and Submerged Fermentation of Penicillium expansum KACC 40815
Penicillium spp. are known to harbor a wide array of secondary metabolites with cryptic bioactivities. However, the metabolomics of these species is not well-understood in terms of different fermentation models and conditions. The present study involved metabolomics profiling and transcriptomic analysis of Penicillium expansum 40815 under solid-state fermentation (SSF) and submerged fermentatio...
متن کاملSolid State Fermentation for Production of Chitosan by Aspergillus Niger
The effect of Solid State Fermentation (SSF) on Chitosan production by A. niger was investigated. A. niger BBRC 20004 from Biochemical and Bioenvironmental Research Centre of Sharif University of Technology (Tehran, Iran), was grown on corn residue. Chitosan was extracted from the fungal mycelia using hot alkaline and acid treatment. A. niger was incubated for 12 days on corn residue with moist...
