Bertoldi and Civilini (2006) carried out a composting process in two separate reactors first, only in the thermophilic phase, with the purpose of pathogen destruction and decomposition by selected thermophilic microorganisms second, only in the mesophilic phase, to perform the main microbial transformations with a higher... 

Heterotrophic fermentation leading to H2 production can be carried out by a wide variety of mesophilic and thermophilic microorganisms under anoxic conditions.

Special attention has been paid by sevo groups to cloning xylanase genes from thermophilic microorganisms as a source of thermostable xylanases. Cloning of such genes in mesophilic recepients offers a convenient way to purify xylanases simply by a heat denaturation of the more heat-labile proteins of the host (54). Applications are limited to those enzymes that possess thermostability considerably higher than the majority of the host cell proteins. 

Unlike conventional systems, the AFC uses thermophilic microorganisms that thrive in environments roughly 110 to 160°F.

Thermophilic microorganisms are able to utilize a wide range of organic wastes, such as residues from the food-processing industry (12). Paper sludge is another industrial waste with relatively high cellulose content, which could provide for an interesting feedstock after, e.g., enzymatic... 

Natural thermostable enzymes are expected to be a good model for engineering stabilization of proteins. Study of thermostable enzymes from thermophilic microorganisms has revealed that the hydrophobicity of hydrophobic core inside the protein molecule and the electrostatic interactions of amino acid residues within the folded protein seem to be the cause of their stability. The enzymes from thermophilic microorganisms known so far do not contain the disulfide bond, but aqualysin I. Aqualysin I is an extracellular protease while the others are intracellular enzymes.

A dairy farm processing 100 ton of milk per day produces approximately the same quantity of organic products in its effluent as would a town with 55,000 residents. However, legislative regulations for the dumping of whey are forcing industries to come up with alternatives to make this process of elimination environmentally safer. One with attractive potential involves the use of thermophilic microorganisms to produce a... 

In addition to being used in the whole-cell systems, n-hydantoinases are also commercially available as purified or partially purified enzymes in both free and immobihzed forms. A chemist can easily test tliese enzymes for preparation of a specific target amino acid, and scale up the process to produce large-quantity materials. Boehringer Mannheim offers two types of immobilized n-hydantoinases, D-Hydl and D-Hyd2, in both research and bulk quantities. The enzymes are cloned from thermophilic microorganisms and expressed and overproduced...
