Mutants of Penicillium janthinellum NCIM 1171 were evaluated for cellulase production using both submerged fermentation (SmF) and solid state fermentation (SSF). Mutant EU2D-21 gave highest yields of cellulases in both SmF and SSF. Hydrolysis of Avicel and cellulose were compared using SmF and SSF derived enzyme preparations obtained from EU2D-21. Surprisingly, the use of SSF derived preparatio...
(SSF) is an economical alternative technique to submerged fermentation (SmF) for large scale production of industrial enzymes, where raw materials and processing is cheap with reduced chemical cost and less processing risk. It is defined as ‘the growth of microorganisms (mainly fungi) on moist solid materials in the absence of free flowing water’ [1]. This technique uses agricultural substrates...
A greenhouse experiment was performed to evaluate the effects of plant growth-promoting rhizobacteria (PGPR) on nodulation, biological nitrogen fixation (BNF) and growth of the common bean (Phaseolus vulgaris L. cv. Tenderlake). Single and dual inoculation treatments of bean with Rhizobium and/or PGPR were administered to detect possible changes in the levels of and interactions between the phy...
Evaluation of twelve medium components on lipase production by Bacillus sphaericus MTCC511 in submerged batch fermentation was studied using the Plackett-Burman statistical experimental design. The most significant variables affecting lipase production were found to be glucose, olive oil, peptone, NaCl and MnSO4 · H2O. Maximum lipase activity of 2.82 U ml–1 was obtained in the batch fermentatio...
In the present investigation, we report that statistical design and optimization of significant variables for the microbial production of citric acid from sucrose in presence of filamentous fungi A. niger NCIM 705. Various combinations of experiments were designed with Central Composite Design (CCD) of Response Surface Methodology (RSM) for the production of citric acid as a function of six var...
BACK GROUND For enzyme production, the costs of solid state fermentation (SSF) techniques were lower and the production higher than submerged cultures. A large number of fungal species was known to grow well on moist substrates, whereas many bacteria were unable to grow under this condition. Therefore, the aim of this study was to isolate a highly efficient strain of Bacillus sp utilizing wheat...
The bioconversion of fruit wastes into single cell protein production has the potential to solve the worldwide food protein deficiency by obtaining an economical product for food and feed. Using food processing leftovers in the production of single cell protein as substrate would alleviate pollution. In this work cucumber and orange peels were evaluated for the production of single cell protein...
conclusions orange peel essential oil did not reduce postpartum depression and anxiety. background mothers are vulnerable to mental disorders, such as depression and anxiety, in the 6-week postpartum period after delivery. objectives this study was performed to determine the potential effect of orange peel essential oil on postpartum depression and anxiety. patients and methods this double-blin...
While chiral 2,3-Butanediol (2,3-BD) is currently receiving remarkable attention because of its numerous industrial applications in the synthetic rubber, bioplastics, cosmetics, and flavor industries, 2,3-BD-mediated feedback inhibition of Paenibacillus polymyxa DSM 365 limits the accumulation of higher concentrations of 2,3-BD in the bioreactor during fermentation. The Box-Behnken design, Plac...
