Abstract
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 °C. The present investigation can provide a new low-cost carbon source for BC preparation and lead towards commercialization and industrial scale up BC.
