Bio-ethanol production by a novel autochthonous thermo-tolerant yeast isolated from wastewater.

ABSTRACT:

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, wastewater samples from a starch producer plant in Varamin, Iran were used. The isolates were identified by molecular characterization. Characteristics of the isolated strains were determined at 30, 35, 40 and 45°C for 48 hours.

Results

50 yeast strains capable of growing well in agar plates in a temperature range of 30-45°C were isolated. Out of the isolated strains, only three strains
