Abstract

The objective of this study was to evaluate quantitative and qualitative EPS production potency of endophytic Citrus limon (Lemon) leaf isolates D, N and A which are identified as Bacillus spp. according to their morphological characteristics. Endophytic Isolate D identified as Bacillus subtilis, Endophytic Isolate N identified as Bacillus tequilensis and Endophytic Isolate A identified as Bacillus amyloliquifaciensthrough16s rRNA nucleotide gene expression study. EPS production studied using different sugars 5% sucrose, 5% lactose and 5% dextrose. Fourier transform infrared spectroscopy (FTIR) was performed of EPS produced by isolates D, N and A in 5%sucrose to know functional group presents in it.

Keywords: Endophytes; Exopolysaccharide; FTIR
