The samples were analyzed for proximate composition as the raw material influence the bioconversion process which further decides the approaches to be followed for the processing of the material. The carbohydrate profiling of C. forskohlii roots [40] showed that it to be a rich source of starch (18-20%), cellulose (14-15%), hemicelluloses (6-7%) and pectin (3-4%). This suggested the possible use of root biomass for production of biobutanol.
