Heat Resistant Mesophilic Microorganisms

Heat-shock Response in Thermophilic Microorganisms

Microorganisms resistant to free-living amoebae.

Free-living amoebae feed on bacteria, fungi, and algae. However, some microorganisms have evolved to become resistant to these protists. These amoeba-resistant microorganisms include established pathogens, such as Cryptococcus neoformans, Legionella spp., Chlamydophila pneumoniae, Mycobacterium avium, Listeria monocytogenes, Pseudomonas aeruginosa, and Francisella tularensis, and emerging patho...

Conversion of municipal solid waste to carboxylic acids using a mixed culture of mesophilic microorganisms.

Waste biomass was anaerobically converted to carboxylate salts by using a mixed culture of acid-forming microorganisms. Municipal solid waste (MSW) was the energy source (carbohydrates) and sewage sludge (SS) was the nutrient source (minerals, metals, and vitamins). Four fermentors were arranged in series and solids and liquids were transferred countercurrently in opposite directions, which all...

Dietary habits and gastrointestinal colonization by antibiotic resistant microorganisms.

Sir, The human gastrointestinal flora is affected by probiotics such as lactobacilli, the use of antibiotics and, last but not least, dietary habits. It appears obvious that intestinal metabolism and mucosal immunity change with the type of food intake, which is also correlated with changes in the ratio in which different microorganisms occur. Antibiotics, like food, greatly affect the composit...

THE OXIDATION RESISTANCE OF HIGH ALUMINUM HEAT RESISTANT STEELS

Abstract: In this research, the oxidation behaviour of high Aluminum heat resistant steel (%25Cr,%20Ni,%8Al) hasbeen evaluated at the temperature range of (1000-1300ºC).The results showed that there was no countinous healinglayer on the surface of the alloy when Al increased up to %5.5 and the oxidation resistance of steel decreased due toformation of spinel oxides on the surface.By increasing ...
