background and objective: in the present study, bacillus polymyxa ncim no. 2539 was selected to utilize agro-industrial byproduct (orange peel) for amylase production under submerged fermentation conditions. material and methods: different agro-industrial byproducts like cane molasses, wheat bran, rice bran and orange peel were screened for maximum amylase production. amylase activitiy of bacil...
A novel strain Rhizopus sp. C4 was isolated from compost for the production of pectinase. Cultivation of Rhizopus sp. C4 on orange peel substrate under various solid-state fermentation (SSF) conditions was evaluated for pectinase yield along with the enzyme activity profile as a potential, low-cost alternative to submerged-liquid fermentation. Response surface methodology (RSM) was employed to ...
Amylase production by Bacillus licheniformis isolated from fish gut was statistically optimized using grape fruit peels in submerged fermentation. Nutritional parameters were through one factor at a time approach. The selected as carbon source, ammonium nitrate nitrogen magnesium sulphate mineral salt. These along with initial medium pH central composite design of response surface methodology. ...
Production and purification of alpha-amylase by probiotic Lactobacillus plantarum MTCC 1407 has been investigated under submerged fermentation using Mann Rogassa Sharpe medium containing (1%) soluble starch in lieu of glucose (2%) as carbon source. Response Surface Methodology was used to evaluate the effect of main variables, i.e. incubation period, pH and temperature on enzyme production. A f...
Pectinases (EC 3.2.1.15) are a class of enzymes that catalyze the depolymerization or de-esterification reactions degrade pectic substances. In present study, we have isolated Aspergillus niger strain from soil samples, in India and evaluated pectinase production. The highest producing A. was further optimized with various agricultural wastes. Plackett-Burman design (PBD) Central composite ‘(CC...
The optimization of submerged culture of the culinary-medicinal golden oyster mushroom, Pleurotus citrinopileatus, was studied using a one-factor-at-a-time, two-stage stimulation and central composite rotatable design to produce mycelia with high ergothioneine content. The optimal culture conditions for mycelia harvested at day 22 were a temperature of 25°C, an inoculation ratio of 5%, 2% gluco...
The bacterial strain producing thermostable, alklophilic alpha-amylase was identified as Bacillus amyloliquefaciens KCP2 using 16S rDNA gene sequencing data (NCBI Accession No: KF112071). Medium components were optimized through the statistical approach for the synthesis of alpha-amylase by the organism under solid-state fermentation using wheat bran as the substrate. The medium components infl...
Process optimization for citric acid production from raw glycerol using response surface methodology
Statistical experimental design was applied for the optimization of medium constituents for citric acid production by Yarrowia lipolytica NCIM 3589 in submerged fermentation using raw glycerol as the carbon source. Response surface methodology (RSM) involving central composite design (CCD) was adopted to evaluate the amount of citric acid produced by most important factors, such as carbon conce...
Agro-industrial wastes are mainly composed of complex polysaccharides that might serve as nutrients for microbial growth and production of enzymes. The aim of this work was to study polygalacturonase (PG) production by Aspergillus niveus cultured on liquid or solid media supplemented with agro-industrial wastes. Submerged fermentation (SbmF) was tested using Czapeck media supplemented with 28 d...
background and objective: sorbitol is a non-toxic and slightly hygroscopic compound with different applications. zymomonas mobiles produces sorbitol from sucrose or mixtures of glucose and fructose (formation is coupled with the dehydrogenation of glucose to glucono-δ- lactone). recombinant zymomonas mobilis may produce sorbitol and gluconic acid from glucose and fructose using different divale...
