Immobilized yeast cells in agar gel beads were used in a packed bed reactor for the production of ethanol from cane molasses at 30°C, pH 4.5. The maximum productivity, 79.5g ethanol/l.h was obtained with 195g/l reducing sugar as feed. Substrate (64.2%) was utilized at a dilution of 1.33h-1. The immobilized cell reactor was operated continuously at a constant dilution rate of 0.67h-1 for 100 days. The maximum specific ethanol productivity and specific sugar uptake rate were 0.610g ethanol/g cell… Expand
Enhanced production of ethanol from free and immobilized Saccharomyces cerevisiae under stationary culture.
In the present work, studies were carried out on the ethanol production by free and immobilized Saccharomyces cerevisiae GC-IIB31 under stationary culture. Cane molasses in different concentrationExpand
Performance of different immobilized-cell systems to efficiently produce ethanol from whey: fluidized batch, packed-bed and fluidized continuous bioreactors
BACKGROUND: The bioconversion of whey into ethanol by immobilized Kluyveromyces marxianus in packed-bed and fluidized bioreactors is described. Both batch and continuous cultures were analyzed usingExpand
Bioethanol Production Using Saccharomyces cerevisiae Immobilized in Calcium Alginate–Magnetite Beads and Application of Response Surface Methodology to Optimize Bioethanol Yield
We studied the bioethanol production in molasses-based medium by yeast Saccharomyces cerevisiae immobilized in calcium alginate magnetite beads (CAMB). The yeast was isolated from soil samplesExpand
Dynamics of yeast immobilized-cell fluidized-bed bioreactors systems in ethanol fermentation from lactose-hydrolyzed whey and whey permeate
Repeated batches of fluidized-bed bioreactor on concentrated LHWP led to increased ethanol productivity, reaching 2.8 g L−1 h−1, while single cultures of S. marxianus CCT 4086 cultures produced the best results in both media. Expand
Influence of pH and Initial Glucose Concentration on the Growth of Saccharomyces cerevisiae Yeast Strain by Gravitational Field Flow Fractionation
Gravitational field-flow fractionation (GrFFF) was applied for the study of the growth of Saccharomyces cerevisiae yeast strain, in the presence or the absence of corn and wheat starch granules asExpand
It has been reported in literature that Z. mobilis has two types of alcohol dehydrogenase gene (ADH), one is Zinc inducible, and another is Iron (Ferrous) inducible. Therefore, it was attempted toExpand
The alcoholic fermentative efficiency of indigenous yeast strains of different origin on orange juice
The alcoholic fermentative ability of yeast strains; Saccharomyces cerevisiae (isolated from yam), S. cerevisae (from sugarcane molasses, S. carlsbergensis and S. ellipsoideus (from orange juice) were examined on orange juice. Expand
Sustainable Embedding of the Bioplastic Poly-(3-Hydroxybutyrate) into the Sugarcane Industry: Principles of a Future-Oriented Technology in Brazil
To make the biodegradable polymer poly-(3-hydroxybutyrate) (PHB) economically competitive with common end-of-pipe plastic materials from petrochemistry, the production costs have to be reducedExpand
Quantitation of alcohols in orange wine fermented by four strains of yeast
Gas liquid chromatography was used to identify the types of alcohol present in wines produced by fermenting orange juice with four strains of yeast; Saccharomyces cerevisiae (isolated from yam), S.Expand
Formation of indigoidine derived-pigments contributes to the adaptation of Vogesella sp. strain EB to cold aquatic iron-oxidizing environments
Results of this study suggested an active role of strain EB in the investigated iron-oxidizing ecosystem of Andean Patagonia, Argentina, and pigmented cells were more tolerant to freezing than non-pigmented cells, suggesting a role of cryoindigoidine/indigoidsine as a cold-protectant molecule.

Continuous ethanol fermentation using immobilized yeast cells
It was confirmed that 8–10%(v/v)ethanol‐containing broth was continuously produced from nonsterilized diluted cane molasses for over one‐half year and entrapment of sterol and unsaturated fatty acid into immobilized gel beads enhanced ethanol productivity more than 50 g ethanol/L gel h and prolonged life stability for more than one-half year.
