Degradation of agrowastes by lignocellulolytic activity of bacterial isolates from marine sources

Bacterial isolates which posse’s lignocellulolytic ability for industrial purposes are rare. In the present study, the ability of the marine microorganism to degrade cellulose, lignin and hemicelluloses is carried out, which acts as the preliminary analysis to identify the potential of the microorganisms. The microorganisms were subjected to degrade 18 different agro waste which contain less amount of starch and carbohydrate and high amount of lignocellulosic complex. The biochemical conversion to simpler sugars for each substrate by the bacterial isolates was determined by DNS and lignin assay. Bacillus pumilus and Mesorhizobium sp., showed maximum degradation in rice straw, ragi straw, paper and eucalyptus. Cellulose degradation was seen maximum in the 5th week and lignin assay was maximum in 3rd week. Among the two isolates Bacillus pumilus exhibited a more efficient enzymatic hydrolysis of the substrates when compared to Mesorhizobium sp., These isolates can be used for commercial scale enzymatic
