Pectinase production by Bacillus subtilis and its potential application in biopreparation of cotton and micropoly fabric

Purification and Characterization of Alkaline Pectin Lyase from a Newly Isolated Bacillus clausii and Its Application in Elicitation of Plant Disease Resistance

“…At 40°C, enzyme production began after 12 h of incubation and peaked at 72 h, decreasing gradually thereafter. Similarly, Ahlawat et al reported the alkaline pectinase production by B. subtilis at an optimal temperature of 37°C [4]. The maximum alkaline PNL yield of 4,180 U/g dry sugar beet pulp was obtained after 72 h of incubation at 40°C with sugar beet pulp as a carbon source and wheat bran as a nitrogen source.…”

“…The production of pectinases by microorganisms have been studied with several natural and purified carbon sources, and a great attempt have been done for the utilization of agroindustrial wastes like wheat bran, lemon peel, apple, and orange bagasses [32]. Although the production of alkaline pectinase and PNL by SSF has been reported extensively, no report describes the use of sugar beet pulp in alkaline PNL production in SSF [4,7]. The beet sugar industry is one of the most important industries in northern China.…”

“…Pectinases are today one of the upcoming enzymes of the commercial sector [3]. Based on their mode of action, pectinases include polygalacturonase, pectin esterase, pectin lyase (PNL), and pectate lyase [4]. Pectinases are classified as an endo-or exo-pectinase depending on whether the cleavages are random or endwise [5].…”

Fermentative Production of Microbial Enzymes and their Applications: Present status and future prospects

“…The reasons for application of microorganisms for production of enzymes in industries are selected after thorough screening process for improvement in enzyme efficiency. Broths subjected to fermentation process are comprised of target protein in higher concentration together with other components present in media, specifically salts and carbohydrates [1][2][3][4][5][6][7][8][9][10][11][12][13]. Fermentation method involving downstream processing is useful to carry out extraction, filtration and separation process to remove impurities from the medium [14,15].…”

The design of a novel, environmentally improved, industrial cotton pre-treatment process

“…These studies focused on two aspects for the use of cellulase in cotton pre-treatment: 1. degradation of seed coat fragments [Tavcer, 2008]; 2. degradation and destabilization of the primary wall [Ahlawat et al 2009, Anis & Eren, 2002, Csiszar et al, 2006, Karapinar & Sariisik, 2004.…”
