Continuous Thermophilic

SCHULZE, K. L. (Michigan State University, East Lansing). Continuous thermophilic composting. Appl. MIicrobiol. 10:108-122. 1962.Under complete mixing conditions, aerobic decomposition of mixed organic waste materials has been maintained continuously in the thermophilic phase in a 55-gal rotating drum. Temperatures ranged between 53 and 70 C. Raw material was added daily or every second day in ...

Evaluation of thermochemical pretreatment and continuous thermophilic condition in rice straw composting process enhancement.

The effects of thermochemical pretreatment and continuous thermophilic conditions on the composting of a mixture of rice straw residue and cattle manure were investigated using a laboratory-scale composting reactor. Results indicate that the composting period of rice straw can be shortened to less than 10 days by applying alkali pre-treatment and continuous thermophilic composting conditions. T...

Co-digestion of polylactide and kitchen garbage in hyperthermophilic and thermophilic continuous anaerobic process.

Two series of two-phase anaerobic systems, consisting of a hyperthermophilic (80°C) reactor and a thermophilic (55°C) reactor, fed with a mixture of kitchen garbage (KG) and polylactide (PLA), was compared with a single-phase thermophilic reactor for the overall performance. The result indicated that ammonia addition under hyperthermophilic condition promoted the transformation of PLA particles...

A novel Acidimicrobium species in continuous cultures of moderately thermophilic, mineral-sulfide-oxidizing acidophiles.

A novel species of Acidimicrobium appeared to be the predominant ferrous iron oxidizer in a mixed culture that effected the continuous, efficient extraction of nickel from a mineral concentrate at 49 degrees C, but it was not isolated in pure culture. It outcompeted Acidimicrobium ferrooxidans, which was expected to have a major role in iron oxidation in reactors gassed with air, and was outnum...

Extracellular xylanase production by two thermophilic alkali-tolerant Bacillus strains in batch and continuous cultures.

Xylanase production of newly isolated thermophilic alkali-tolerant Bacillus sp. strain SP and strain BC was investigated in batch and continuous cultures. Enzyme synthesis was inducible with both strains and was observed only in xylan-containing media. Xylan from oat spelt is a better inducer than xylan from birch for strain Bacillus sp. BC while such difference was not observed for strain SP. ...
