Ecofriendly green biosynthesis of bacterial cellulose (BC) using a low-cost carbon source from the shell extract of Sapindus mukorossi was studied by Komagataeibacter xylinus B2-1. After 7 d of incubation, strain B2-1 produced 1.31 g L-1 BC, which had similar micro-morphology and structural properties to that from Hestrin-Schramm medium based on scanning electron microscopy, X-ray diffraction and Fourier transform infrared analyses. While strain B2-1 grew well and produced BC efficiently at pHs ranging from 4.0 to 6.0, the considerable BC production was only found at temperature of 30 degrees C. The present investigation can provide a new low-cost carbon source for BC preparation and lead towards commercialization and industrial scale up BC. [GRAPHICS] .
