BACKGROUND It has been known for years that ethanol is a bio-fuel to replace fossil fuels. The ethanol industry requires the utilization of micro-organisms capable production with stresses. The purpose of present study was to isolate and characterize ethanologenic yeast with high potential application at high temperature to produce bio-ethanol. METHODS To isolate ethanologenic yeasts, wastewa...

17 The presence of dyes in wastewater effluent of textile industry is well documented. In 18 contrast, the endocrine disrupting effects of these dyes and wastewater effluent have been 19 poorly investigated. Herein, we studied twenty-three commercial dyes, usually used in the 20 textile industry, and extracts of blue jean textile wastewater samples were evaluated for their 21 agonistic and anta...

thermoplastic starch (tps) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure tps materials. further investigations on tps: pvablends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...

In this paper, the term “leafy-floury silage” was used to describe corn silage hybrids evaluated in study. However, studied did not contain leafy gene nor they a (floury gene, opaque-1 or opaque-2 gene) that would result kernels containing mostly floury endosperm. The were conventional standard/yellow dent varieties. terms “starch” and “floury as common industry define differences ruminal starc...

Hydrogen sulfide, which is produced by sewer biofilms as a result of sulfate reduction under anaerobic conditions, has since long been identified as a major cause of corrosion and odour problems in a sewer system. Dosing of various types of chemicals to wastewater is widely used by the water industry as a control measure for these problems. Oxygen/air, nitrate salts, iron salts and magnesium hy...

Renewable energy is an increasing need in our society. Microbial fuel cells (MFCs) represent a new method for treating wastewater and simultaneously producing electricity. In the present study, we demonstrated the feasibility of bioelectricity generation from brewery wastewater treatment using a mediator less MFC at different pH. We also demonstrated that addition of readily utilizable substrat...

In this study, the removal of mercury ions by cellulose of Acetobacter xylinum was investigated in the synthetic and chlor-alkali wastewater. Biofilms of Acetobacter xylinum were grown in laboratory column bioreactors. The biofilms were continuously treated with sterile synthetic model wastewater or nonsterile, neutralized chloralkali wastewater.The extent of adsorption was studied as function ...

It is based on the experiments conducted for study of chromium removal and recovery from chrome tanning waste water of leather industry for chromium removal about 98.5% was achieved at pH 8.0 and at this pH reduction of COD is 61.5 % and percentage for removal of color from the wastewater of leather industry is 99.5% under applying the batch experimental condition. For this purpose, it is carri...

The milk processing industry is one of the world's staple industries, thus the treatment possibilities of dairy effluents have been attracting more and more attention. The purpose of the paper is to review contemporary research on dairy wastewater. The origin, categories, as well as liquid by-products and general indicators of real dairy wastewater are described. Different procedures applied fo...
