Unstable oil markets with rising environmental concerns have revived widespread interest in production of biofuel from renewable materials. Cellulosic materials are abundant and prominent feedstocks for cost effective bioethanol production. A progressive move towards the sustainable and renewable energy sources has been started with the continuous depletion of conventional fossil fuels, rise in energy consumption and emission of greenhouse gas. Bioethanol is a proficient alternative fuel that can be biologically produced from waste materials and feedstock. In present investigation the...

Unstable oil markets with rising environmental concerns have revived widespread interest in production of biofuel from renewable materials. Cellulosic materials are abundant and prominent feedstocks for cost effective bioethanol production. The current study deals with bioethanol production from pretreated Saccharum spontaneum with employment of strain improvement of Saccharomyces cerevisiae. Alkaline pretreatment with 2 % NaOH resulted in increased cellulose content to 82 %. Optimal conditions for saccharification were found to has significantly (p 0.05) elevated saccharification rate with...

With the surprising development across the cosmetic and personal care companies the re-utilization of cosmetic tools is of a common practice. Isolation and detection of human skin pathogens from 100 samples of beauty salon tools i.e., blusher brush, face sponge and wax has been done. All the samples were examined microbiologically for the contamination of Staphylococcus aureus, Pseudomonas aeruginosa, yeast and fungus. It was observed that the percentage of Staphylococcus aureus was higher (100% in sponge, 100% in brush, 88% in wax) in the tools than Pseudomonas aeruginosa (69.6% in sponge,...

There are reports of food borne illnesses associated with the consumption of fruit juices and a lot of food borne illnesses have been reported at several places all over the world. Pakistan is one of the culprits of this issue. Present study was undertaken for detection of the possible sources of E.coli O157: H7 in street vended fresh fruit juices sold along the road sides of Lahore city, Pakistan which maintain unhygienic conditions and assessed its safety for human consumption.162 fresh juice samples of sugar cane, plum, tamarind, peach, lemonade and slush that were taken from different...

Enzyme production from lignocellulosic biomass is sustainable owing to their ubiquitious nature and non-competitivness with food crops. Agrowastes accumulate in envonment in substantial amounts as pollutants, and primarily comprise of cellulose and hemicellulose that can be saccharified by cellulases to produce fermentable sugars yielding bioethanol. However, cellulase production cost is major impediment in bioenergy production scenario. Saccharum spontaneum is an abundantly found agrowaste with high cellulose content which can be employed for cellulase production through biological route. In...
