In vitro study of lipid biosynthesis in an anaerobically methane-oxidizing microbial mat

Article Abstract:

The results of long-term in vitro incubations with (super 13)CH(sub 4) of a microbial mat from the Black Sea with high anaerobic oxidation of methane (AOM) activity are described. It is observed that there were differences in (super 13)C uptake into the lipids of the sulfate-reducing bacteria (SRB) than into the lipids of archaea supports the hypothesis that there is autotrophic growth of SRB on small methane-derived carbon compounds supplied by the methane oxidizers.

Comparison of assimilable organic carbon and UV-oxidizable carbon for evaluation of ultrapure-water systems

Article Abstract:

A comparative study between assimilable organic carbon (AOC) and ultraviolet-oxidizable carbon (UV-OC) was conducted to know which technique has greater advantage in assessing bacterial growth potential in ultrapure water systems. Water samples were collected from an ultrapure- water pilot plant. Assay results showed AOC to be more advantageous than UV-OC in measuring the availability of nutrients which can be utilized by bacteria for their growth and maintenance.

Inhibitory effect of maillard reaction products on growth of the aerobic marine hyperthermophilic Archaeon Aeropyrum pernix

Article Abstract:

Results demonstrate strong inhibitory effect of reducing sugars and tryptone on the growth of Aeropyrum pernix archaeon. Data indicate the inhibitory effect is due to the production of Maillard reaction products, which is enhanced under aerobic conditions. Furthermore, drastic growth inhibition is seen with the addition of Maillard reaction products to the culture medium.
