Some Aspects of Thermophilic and Extreme Thermophilic Anaerobic Microorganisms
1981In this presentation, we have discussed that the acetogenic thermophilic bacterium, Clostridium thermoaceticum, ferments glucose almost quantitatively to acetate. That part of the acetate is formed from CO2, which functions as the electron sink. We have demonstrated that enzymes in the acetate formation contain trace elements such as iron, cobalt ...

Thermophilic Adaptation of Proteins
Critical Reviews in Biochemistry and Molecular Biology, 2001Hyperthermophilic organisms optimally grow close to the boiling point of water. As a consequence, their macromolecules must be much more thermostable than those from mesophilic species. Here, proteins from hyperthermophiles and mesophiles are compared with respect to their thermodynamic and kinetic stabilities.

Trends in Ecology and Evolution, 1991
Interest in the ecology, physiology and evolution of microorganisms adapted to growth at relatively high temperatures (up to 110-degrees-C) has increased enormously during the past two decades. This interest was stimulated by the discovery of marine hydrothermal vent ecosystems, and also by awareness of the potential of thermophilic microbes in ...

Thermophilic microorganisms in biomining
World Journal of Microbiology and Biotechnology, 2016Biomining is an applied biotechnology for mineral processing and metal extraction from ores and concentrates. This alternative technology for recovering metals involves the hydrometallurgical processes known as bioleaching and biooxidation where the metal is directly solubilized or released from the matrix for further solubilization, respectively ...

Thermophilic Toluene Biofiltration
Journal of the Air & Waste Management Association, 1999Thermophilic biodégradation of toluene with active compost biofilters was studied. Thermophilic conditions were maintained either by daily substrate addition (semicontinuous composting) or with a heating system (batch thermophilic composting). The semicontinuous system was designed for the treatment of cool (less than approximately 35 °C) gases under ...

Thermophilic Ethanol Fermentations
1981Thermophilic ethanol fermentations are of interest to industrial alcohol production because both the pentose and hexose fraction of biomass can be directly fermented in high yield (i.e., mol ethanol/mol substrate consumed), and because of potential novel process features associated with high temperature operation.

Industrial prospects for thermophiles and thermophilic enzymes.
Biochemical Society symposium, 1986Reasons for enzyme instability are discussed. Thermophiles are a promising source of more stable intracellular enzymes. This aids their purification as well as providing desirable industrial properties. The organisms themselves have advantages for high temperature fermentations, e.g. for ethanol production. Systems for cloning genes into them are under

Identification of thermophilic actinomycetes
Journal of Allergy and Clinical Immunology, 1978be separated into two groups. Group A lacked likely that T. candidus is synonymous with T. vulamylase and tyrosinase and did not produce malanin, garis and may resemble T. thalpophilus or T. antibiotwhile Group B produced both enzymes and melanin. icus, since they inhibit nonmelanin-producing colThe absence of amylase was noted by Tsiklinsky in onies ...
