การคัดเลือกและแยกแบคทีเรียที่มีประสิทธิภาพในการสร้างเอนไซม์กลุ่มเซลลูโลไลติก จากทางเดินอาหารของหนอนนก Tenebrio molitor (SCREENING AND ISOLATION OF CELLULOLYTIC ENZYMES PRODUCING-POTENTLAL BACTERIA FROM THE GUT OF TENEBRIO MOLITOR)
Abstract
The objectives of this study were to isolate and screen for cellulase, xylanase and pectinase producing microorganism form the gut of Tenebrio molitor. In this study, screening of cellulase, xylanase and pectinase producing microorganism by serial dilution and selective plating technique. The results showed that at least different 11 isolates of microorganism were be isolated from the samples. Only 6 isolates were able to produce cellulase, 9 isolates exhibited to produce xylanase and only 2 isolates indicated to produce pectinase. The enzyme activity assay indicated the highest cellulase, xylanase and pectinase producing strain was MW-I, MW-IV and MW-IX, respectively. The enzyme activity assay revealed that the cellulase, xylanase and pectinase producing –isolated bacteria strains were 1.150, 0.544 and 0.934 Unit/ml respectively. Molecular identification of 16S rRNA gene indicated that isolates MW-I was similarity Enterococcus spp., (98%) MW-IV was similarity Staphylococcus spp. (99%) and MW-IX similarity was Bacillus spp. (98%)
