Changes in membrane fatty acid composition of Pediococcus sp. strain NRRL B-2354 in response to growth conditions and its effect on thermal resistance
Article Abstract:
Pediococcus sp. is a facultative, non-spore forming, spherical and gram-positive aerobic bacterium that was originally isolated from milk and dairy utensils. It non-pathogenicity and thermal resistance has made it an ideal test organism for studying the destruction of bacteria by microwave energy in most foods. An experiment was conducted involving the membrane fatty acid composition and thermal resistance of Pediococcus sp. Findings have indicated that the membrane fatty acid composition of the bacterium is dependent on the growth conditions and that these bacterium compositions are responsible for the thermal resistance capability.

Immunomagnetically captured thermophilic sulfate-reducing bacteria from North Sea oil field waters
Article Abstract:
Immunomagnetic beads coated with antibodies against target cell surface antigens were used to capture two species of sulfate-reducing bacteria in oil field waters in the North Sea. Strains of Thermodesulfobacterium mobile and Desulfotomaculum spp. were obtained using this immunomagnetic capture technique. This technique allows selective extraction of specific strains from primary enrichment cultures. Immunomagnetic capture is potentially useful in obtaining pure cell strains forculture studies.

Use of phospholipid fatty acids and carbon source utilization patterns to track microbial community succession in developing compost
Article Abstract:
A study was conducted to analyze microbial community changes in composting dairy waste. Carbon source utilization and phospholipid fatty acid analyses were utilized to carry out study. The temperature in the compost piles was maximal at the beginning sampling time. Results indicated the presence of more thermophiles and fewer bacteria with continued compost development. Findings also showed that microbial utilization of gamma-aminobutyric acid increased over time.
