Kinetics of Colony Formation by Sulfate-Reducing Bacteria

چکیده
The colony formation of sulfate-reducing bacteria, Desulfovibrio desulfuricans and Desulfotomaculum orientis, on agar plates well fitted the theoretical curve of the FOR model proposed by Hattori (1985) The estimates of A for both strains dropped from 5 to I day-1 with cultivation in a liquid medium or starvation in a buffer solution, while that of tr was not affected so much The estimates of h and tr for D. desulfuricans were markedly affected by incubation temperature and lactate concentration in the agar medium Both factors also affected the tr value for D orientis, however only incubation temperature affected the A value for the latter organism

Ghale-madreseh is the first point that the saline and sulfurous streams flow into Tembi River, one of the well-known saline rivers in Khuzestan province, Iran. This river is one of the main sources of increasing Karun River’s salinity, which is the largest river in Iran in terms of discharge. There are three saline and sulfurous springs (Shour-1, Shour-2m and Namak Springs) as well as a drinkab...

متن کاملA six-well plate method: less laborious and effective method for cultivation of obligate anaerobic microorganisms.
We developed a simple, less laborious method to cultivate and isolate obligate anaerobic microorganisms using a six-well plate together with the AnaeroPack System, designated as the six-well plate method. The cultivation efficiency of this method, based on colony-forming units, colony formation time, and colony size, was evaluated with four authentic obligate anaerobes (two methanogenic archaea...

The current importance of energy emphasizes the use of renewable resources (such as wastewater) for electricity generation by microbial fuel cell (MFC). In the present study, the native sulfate-reducing bacterial strain (R.gh 3) was employed simultaneously for sulfurous component removal and bioelectricity generation. In order to enhance the electrical conductivity and provision of a compatible...
