Kocho and Bula are fermented product of Enset (Ensete ventricosum). It is the staple food for 20 million people in Ethiopia. The aim of study was to isolate, identify and characterize yeast species from fermented kocho and bulla by using Biolog Micro station. 300 Kocho samples were collected from Angacha District. 0.1ml of serially diluted samples were Streaked on yeast pepton dextrose agar and...

To understand the differences in production and secretion patterns between plasmid-harboring and chromosome-integrated recombinant yeasts, the two recombinant Saccharomyces cerevisiae yeasts, containing the structural glucoamylase STA gene and the SUC2 promoter, were investigated. Both systems were regulated by glucose concentration in the culture broth. First, the glucoamylase activity per gen...

two yeast isolates, a4 and a5 of candida membranifuciens and one isolate, a6 of pichia guilliermondii were tested either separately or in mixture for their effectiveness against apple gray mold, caused by botrytis cinerea pres.: fr. as regards the compatibility of the biocontrol agents, it was shown that yeast isolates were compatible with each other in liquid media. results of the experiments ...

Single yeast cells in an agarose solution were patterned using the optically controlled thermocapillary flow surrounding a vapor bubble in the solution. After cell patterning, the agarose solution was gelled, and the cells were able to grow in this 3D biocompatible scaffold. Of the 12 cells in the initial pattern, 11 underwent multiple cell divisions during culturing for nine hours. This opto-t...

chromagar candida is a new chromogenic culture medium that is used for the isolation and direct identification of some of the most clinically important yeast pathogens on the basis of colony colour. the aim of the study was to isolate and identify candida species from the oral cavity with chromagar candida. samples (158) from 68 orthodontic patients wearing upper removable orthodontic appliance...

During chronological aging of budding yeast cells, the culture medium can become acidified, and this acidification limits cell survival.  As a consequence, buffering the culture medium to pH 6 significantly extends chronological life span under standard conditions in synthetic medium.  In this study, we assessed whether a similar process occurs during replicative aging of yeast cells.  We find ...

We describe the design, construction, and operation of a hyperspectral microarray scanner for functional genomic research. The hyperspectral instrument operates with spatial resolutions ranging from 3 to 30 microm and records the emission spectrum between 490 and 900 nm with a spectral resolution of 3 nm for each pixel of the microarray. This spectral information, when coupled with multivariate...

This study presents the results of an experiment in which the effect of addition of a yeast culture (Saccharomyces cerevisiae, Strain 47) on rumen fermentation was studied in thirty-six dairy cows of Holstein breed. The animals were divided into one control and five experimental groups. Each group involved 6 individuals. The animals received a diet consisting of good maize silage with a higher ...
