Utilization of lignocellulosic wastes for xylanase and cellulase production by Paenibacillus curdlanolyticus B6

Bacterial biodegradation and bioconversion of industrial lignocellulosic streams

“…Paenibacillus curdlanolyticus B6 is a facultative anaerobe capable of adhering to xylan and cellulose and producing enzymes that degrade these polysaccharides (Pason et al 2006). Paenibacillus curdlanolyticus B6 was also shown to depolymerize sugars in different types of lignocellulosic waste: corn husk, sugarcane bagasse, and rice straw (Pakdeedachakiat et al 2008). Shi et al (2010) isolated a bacterial multifunctional xylanase from corn ensilage which can bind to and degrade xylan and β-glucan at a pH range of 6-10.…”

Lignocellulosic waste material as substrate for Avicelase production by a new strain of Paenibacillus chitinolyticus CKS1

“…Typically, Paenibacillus sp. produce CMCase (Emtiazi et al, 2007;Pakdeedachakiat et al, 2008;de Castro et al, 2011;Kumar et al, 2012), CMCase and Avicelase with similar activity (Ko et al, 2007;Raddadi et al, 2013) or produce endoglucanase that can degrade Avicel (Ogawa et al, 2007). Therefore, the strain CKS1 is the first Paenibacillus sp.…”

“…is limited and results are difficult to compare with each other due to different growing conditions of microorganisms, different substrates, and different procedures and units used for expressing the enzymatic activity (Pakdeedachakiat et al, 2008;Kumar et al, 2012).While growing of on mineral medium containing corn husk Paenibacillus curdlanolyticus B6 produced cellulases with the highest CMCase activity of 0.12 U/ml, while using sugarcane baggase and rice straw in medium resulted in CMCase activity of 0.07 U/ml and 0.02 U/ml, respectively (Pakdeedashakiat et al, 2008). This enzyme activity is notably lower, than that achieved by P. chitinolyticus CKS1.…”
