Gene expression is the process by which inheritable information from a gene, such as the DNA sequence, is made into a functional gene product, such as protein or RNA. Several steps in the gene expression process may be modulated, including the transcription step and translation step and the post-translational modification of a protein. A wide range of microorganisms produce invertase and can, t...

Various chromatographic, spectrophotometric, and ion exchange procedures have been used recently with somewhat varying results for the analysis of yeast ribonucleic acid for its constituent purine and pyrimidine components (l-5). The reasons for the variations may be due in part to differences in the samples analyzed and in part to deficiencies in the methods used. Some of these deficiencies ha...

A national cohort based on the census at 9 November 1970 and the death registration files from 1970 to 1980 was analysed to see if skilled Danish bakers had an excess of respiratory cancer. The group of skilled bakers was divided into occupational subgroups to try to narrow down the possible causes of cancer. Significant excess mortality was found among skilled bakers in retail bakeries, skille...

The textile industry is one of the biggest industries in the world and its wastewater is one of the most important threats to the environment and human health. In this study, the ability of Haloarcula sp. IRU1 to produce poly(3-hydroxybutyrate) (PHB) was investigated using a basal salts medium. Different factors like textile wastewater, yeast extract, and KH2PO4 (as carbon, nitrogen, and phosph...

bakers are frequently exposed to various irritant chemicals during work which can induce respiratory problems. in this study, pulmonary function tests and self-reported respiratory and allergic symptoms in bakers were compared with matched control subjects. the frequency of respiratory and allergic symptoms was evaluated in a sample of 58 iranian bakers and 58 control subjects using a questionn...

The treatment of the yeast industry wastewater was investigated by nanofiltration (NF) membrane process on a pilot scale. Two wastewaters were used as feed: (i) dilute wastewater with COD 2000 mg/L and (ii) concentrate wastewater with COD 8000 mg/L. The permeate flux, COD retention, color and electrical conductivity (EC) removal were evaluated in relation to trans-membrane pressure and long-ter...

Abstract This study aimed to evaluate the microbiological characteristics of bread dough and nutritional quality “ Tabnen-naow ,” an ethnic artisan consumed mainly in Burkina Faso. Originating Boussé, this is spreading outskirts Ouagadougou for several reasons, such as increase price industrial especially supposed low glycemic index bread. However, there insufficient information literature abou...
