Emission of climate-relevant trace gases and succession of microbial communities during open-window composting
Article Abstract:
The maturation of an open-window compost was analyzed fumigation extraction method to determine the variety of microbial properties during the composting process at a whole-window level. Analysis of compost maturation indicated the presence of high emissions of trace gases such as CO2, methane and N2O during high temperatures. Furthermore, high levels of branched-chain fatty acids were also detected due to an increase in the population of actinomycetes and gram-positive bacteria.

BACTOX, a rapid bioassay that uses protozoa to assess the toxicity of bacteria
Article Abstract:
The overall toxicity of bacterial strains can be effectively monitored using a novel type of bioassay called BACTOX based on the protozoan Tetrahymena pyriformis. The proposed technique is simple and rapid and can detect toxicant-producing bacteria that may present a biohazard. BACTOX can also be utilized for the risk analysis of genetically altered or wild-type microbes designed for deliberate release.

Isolation of Thermus strains from hot composts (60 to 80 C)
Article Abstract:
Several thermophilic bacterial strains related to the genus Thermus are isolated from hot composts at temperatures between 65 and 82 degrees Celsius and subjected to DNA and RNA analyses. Results show that the new Thermus strains are closely related to Thermus thermophilus HB8. The data also suggest that thermophilic oval-spore-forming bacilli are very active during composting at high temperatures.
