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 149.47 ± 1.46 mg/ml release of glucose. It suggested that the utilization of feedstock (Saccharum spontaneum) under its optimum conditions of enzymatic hydrolysis can lead to the augmented sugars release which contributes significantly to the production of bioethanol with a future prospect of industrial exploitation.
In the bio-polishing process, bio-degradable cellulase is used to attack the hair like cellulose substrate of fabric surface and it''s action requires suitable and appropriate process conditions. For this reason, it is very much essential to know about the suitable process parameters like temperature, time and pH upon which the optimum effects of bio-polishing depend. This paper will be very supportive for the industrial people to select an appropriate time, temperature and pH for the bio-polishing of cotton fabrics with cellulase. In this research, bio-polishing was carried out with the cellulase at various process conditions and after that Ends/inch, Picks/inch, GSM, Pilling resistance and Whiteness of cotton fabrics have been determined. From this determination it was possible to assess the effects of bio-polishing.
Aquaculture, Resource Use, and the Environment places aquaculture within the larger context of global population growth, increased demand for sustainable, reliable sources of food, and the responsible use of natural resources. Aquaculture production has grown rapidly in recent decades as over-exploitation and environmental degradation have drastically reduced wild fish stocks. As fish production has increased, questions have persisted about the environmental sustainability of current aquaculture practices. Aquaculture, Resource Use, and the Environment is a timely synthesis and analysis of critical issues facing the continued growth and acceptance of aquaculture practices and products. Chapters look at the past, present, and future demands for food, aquaculture production, and tackle key issues ranging from environmental impacts of aquaculture to practical best management practices in aquaculture production. Providing broad coverage of issues that are essential to the continued development of aquaculture production, Aquaculture, Resource Use, and the Environment will be vital resource for anyone involved in the field of aquaculture.
