Abstract
- A stable aerobic consortium was enriched to degrade crystalline cellulose (Whatman filter paper 1). The degradation efficiency of the consortium after 7 days of incubation was 91% compared to the control. One bacterial isolate, C7, capable of degrading various cellulosic substrates, was obtained from the consortium under aerobic conditions. The sequencing of 16s rDNA revealed that it was related to Paenibacillus sp. It degraded 83% of cotton after 3 days of incubation. The degradation efficiency of Paenibacillus sp. C7 for filter paper, cotton, and avicel was 90%, 90%, and 92% after 5 days of incubation compared to the control. It also degraded non-pretreated agricultural residues efficiently by 70% for rice straw and 46% for wheat bran in 10 days. Scanning electron micrographs (SEMs) of degraded filter paper after 2 days of incubation indicated smoother and thinner fabrics in its structure. It is a potential cheaper candidate for the degradation of lignocellulosic biomass without any pretreatment.
