Microbial endophite from plant sugar-apple 1Isolation, identification, and characterization of mannanase, xylanase and cellulase producing indigenous marine bacteria have been conducted from total 20 isolates. Based on 16S rDNA sequence analysis, three potential isolates are obtained and identified as Bacillus subtilis (M8), Bacillus tequilensis (X4) and Bacillus cereus (C9). The potential strains M8, X4 and C9 can produce mannanase, xylanase and cellulase activities such as 9.5 U/mL; 0.36U/mL;0.56U/mL with optimum pH and temperature 6.0;50°C, 5.5;70°C and 8;50°C, respectively. Based on the TLC analysis, mannanase from M8 and xylanase from X4 has potential to hydrolyzed mannan and xylan for producing oligosaccharides with size around tri-hexasaccharides as a main product.
