The present invention relates to a biomass (kenaf fibre) that can be hydrolyzed to produce lactic acid using bacteria Lactobacillus Rhamnosus as fermenting organism. The above cited prior art D1 defines the general state of the art whereas D2 to D4 seem to have particular relevance to the present invention. D4 disclosed in it detailed description of the invention whereby chemical pre-treatment using sulfuric acid is preferred, hydrolysis of lignocellulosic materials and fermentation process using fermenting organism (preferred bacterial fermenting organism include Strains of Lactobacillus). However, D4 disclosed lignocellulose-containing material is derived from corn stover, corn fiber, hard wood, soft wood, cereal straw, switch grass, Miscanthus, rice hulls, municipal solid waste, industrial organic waste, office paper, or mixtures thereof. Therefore, the present invention seems to be novel but lack of inventive step.
