The present invention provided a process for fractionating a model lignocellulosic biomass, Saccharum spontaneum into two primary carbohydrate (xylose and glucose) fractions. In the present invention, pentose and hexose sugar fractions are obtained separately in single vessel multi-step hydrolysis process from lignocellulosic biomass. A novel processing configuration is used to apply various acid concentrations ranging from 1 to 30 % with continuous steam insertion to the vessel (specially designed glass column); minimizes the generation of inhibitory degradation products. The recovery of total reducing sugars is ca. 95.3% with ca. 99% xylose.

It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
