Available in PDF, EPUB and Kindle. Book excerpt: This research was conducted on the fermentation of ethanol by Saccharomyces cerevisiae using immobilization technique. S. cerevisiae which is also known as Baker's yeast is a single-celled eukaryote that is frequently used in scientific research. It is an attractive model organism due to the fact that its genome has been sequenced, its genetics are easily manipulated and very easy to maintain in the laboratory. Besides, immobilization has already been approved as useful method in maintaining high cell concentration within the reactor, increases the cell's ability to tolerate high ethanol concentration in the medium, allowing higher conversion yield and increased volumetric productivities. Therefore, the purpose of this study is to immobilize the yeast using various kind of supports (e.g: muslin cloth, membrane and sugarcane stalk) in batch processes to determine the best support for ethanol production. In this method, immobilized fermentation was carried out through shake flask seeding technique while the duration of fermentation process was fixed at 10 hours with sampling made at every 2 hours intervals. The germination of the stock and seed culture preparations were conducted followed by the immobilization technique in order to produce ethanol. Samples taken were analyzed for ethanol and glucose concentration, colony forming unit (CFU), biomass concentration, optical density and viewing of S. cerevisiae attachment on immobilized supports by Scanning Electron Microscope (SEM). From the result obtained, it showed that immobilized cloth was capable to increase cell optical density up to 1.602 after 10 hours of fermentation. Moreover, analysis performed by using biomass has revealed that immobilized cloth at 10 hours of fermentation gave the highest biomass concentration which is 39.64 gL-1 and colonies of cells forming at 2.57 x 108/mL of viable cells compared to other materials. Besides, its ethanol productivity was enhanced to 0.42 gL-1h-1, being over 9.6% higher than that observed in the batch culture (0.38 gL-1h-1). The consumption of glucose was improved by 6.9% (compared to batch operation), where nearly 67% of glucose conversion at 10 hours period of immobilized fermentation through muslin cloth. The increment might be associated with the altered metabolical functions in the immobilized cells. This alteration is attributed to the reduction of the diffusion path of the growth nutrient that enhanced the availability and promoted the growth of yeast, thus improving the catalytic conversion of glucose to ethanol. Therefore, the supported muslin cloth was proved to increase the number of cells and glucose inhibition is able to reduce with the utilization of immobilized S. cerevisiae, thus increasing ethanol production.

Book excerpt: Yeast - Industrial Applications is a book that covers applications and utilities of yeasts in food, chemical, energy, and environmental industries collected in 12 chapters. The use of yeasts in the production of metabolites, enzymatic applications, fermented foods, microorganism controls, bioethanol production, and bioremediation of contaminated environments is covered showing results, methodologies, and processes and describing the specific role of yeasts in them. The traditional yeast Saccharomyces cerevisiae is complemented in many applications with the use of less known non-Saccharomyces yeasts that now are being used extensively in industry. This book compiles the experience and know-how of researchers and professors from international universities and research centers.

This book was released on 2014-09-10 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ethanol is an important industrial solvent and a chemical feedstock being used for the synthesis of pharmaceuticals, detergents, adhesives, plastics, plasticizers and host for other chemicals. To reduce the cost of ethanol production, significant improvements in ethanol production technology are needed. The potential advantages of immobilized whole cell system have been recognized in the fermentation of a wide variety of carbohydrates. Immobilized cell technology has many advantages over conventional systems .This study is aimed at cell immobilization process, isolation, purification and immobilization of alcohol dehydrogenase(ADH) on different matrices from cells of S.Cerevisiae for enhancing ethanol production. The cells of Saccharomyces Cerevisiae were immobilized on different matrices viz polacrylamide, k-carrageenan, agar and calcium-alginate .Ethanol Production was improved by immobilized Alcohol Dehydrogenase and further enhanced when cell free extract was co-immobilized with isolated ADH

This book was released on 1996 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The performance of co-immobilized Saccharomyces cerevisiae and glucoamylase was evaluated in a fluidized bed reactor. Soluble starch and yeast extract were used as feed stocks. The biocatalyst performed well and demonstrated no significant loss of activity or physical integrity during 10 weeks of continuous operation. The reactor was easily operated and required no pH control. No operational problems were encountered from bacterial contaminants even though the reactor was operated under non-sterile conditions over the entire course of experiments. Productivities ranged between 25 to 44 g ethanol L−1 h−1. The experiments demonstrated that ethanol inhibition and bed loading had significant effects on bed performance.
