Abstract: In this study, the dilute acid saccarification of plant waste as a lignocellulose biomass for fermentable sugar production as a green fuel has investigated. The Influence of 3 major parameters Temperature, acid concentration and time on produced fermentable sugars has been investigated by response surface model. According to previous studies levels for pretreatment were: temperature (124, 132 and 140oC), process time (30, 40 and 50 minute and sulfuric acid concentration (1, 2, 3%). For this purpose, plant waste was gathered in November of 2015 from Torbat Heidarieh city (Razavi Khorasan, Iran). It was washed by distillated water, air dried and milled to particle size smaller than 50 micrometers and stored in sealed plastic bags at the room temperature. This prepared biomass heated in acid solution in autoclave for determined time. For determination of product filtered solution was analyzed by HPLC and results (Glucose) were modeled by a quadratic equation. Thi

Abstract: Fat poses disposal problem and remain unutilized in eating establishments. We aimed at utilising Catla Catla fish fat as a cheap source of carbon for production of biosurfactant with isolated strains of bacteria. Biosurfactant is itself an eco-friendly and biodegradable chemical with multifunctional activities. We have isolated and characterized a Rhamnolipid biosurfactant produced by P. aeruginosa DSM 50071. It showed enhanced excisional wound healing activity (96%) on topical application at the wound site compared to untreated control rats (p 0.05). The higher tensile strength and higher %wound contraction for the treated group as compared to untreated revealed wound closure efficiency of the biosurfactant. Histopathological study also supported wound closure efficiency by promoting collagen synthesis. Thus our study serves dual purpose of combating environmental pollution - by solving the fish fat disposal problem with its effective utilization and reducing the cost of biosurfatant
