TLDR
A compost production system was employed to supply uniform material for controlled experiments of factorial design and the cumulative amount of CO(2) evolved was maximal at 56 to 60 degrees C.Abstract:
A compost production system was employed to supply uniform material for controlled experiments of factorial design. Over a 96-h composting period, the cumulative amount of CO2 evolved was maximal at 56 to 60°C, an aeration rate that left an O2 residual of 10 or 18% in the exhaust gas and a moisture content of 60% wet weight. Carbon dioxide evolution was submaximal at 64°C and higher.read more

The influence of temperature and moisture contents regimes on the aerobic microbial activity of a biosolids composting blend
TL;DR: In this study, moisture content proved to be a dominant factor impacting aerobic microbial activity of the composting blend and the enhancement of composting activities induced by temperature increment could be realized by increasing moisture content alone.
Journal ArticleDOI
The biology of composting: A review
TL;DR: In this article, the more important aspects of this process with particular emphasis on the microbiological aspects are analyzed, and some attention is also given to hygienic and sanitary implications as well as considerations on plant design.

Effect of temperature on bacterial species diversity in thermophilic solid-waste composting
TL;DR: In this article, a 4.5-liter reactor placed in an incubator maintained at representative temperatures was used to continuously thermophilic composting with a mixture of dried table scraps and shredded newspaper wetted to 55% moisture.

Bacterial Growth Rates above 90°C in Yellowstone Hot Springs
Thomas L. Bott,Thomas D. Brock +1 more
TL;DR: Growth rates of bacteria living in boiling springs have been measured by determining rate of increase in cell numbers on microscope slides immersed in the springs using ultraviolet radiation, and in all cases, slides irradiated at intervals had significantly fewer bacteria than controls.

TL;DR: Much of the earlier work on the heating of moist plant materials was concerned with the nature of the possible agencies responsible, and this has been reviewed fully by Browne (1929).
