Bacteria mesophilic

Summation of mesophilic bacteria, fungi, and thermophilic bacteria. CPU = colony-forming units. 

Mesophilic bacteria A group of bacteria that grow and thrive in a moderate temperature range between 68 F (20 C) and 113 F (45 C). 

Bacteria occur normally in fresh fruit and vegetable tissues. A wide variety of microorganisms have been found on fresh fruits and vegetables, which include mesophilic bacteria, lactic acid bacteria, coliforms, and yeasts and molds (Nguyen-The and... 

Vacuum-steam-vacuum (VSV) treatment resulted in a 1.0-log reduction of aerobic mesophilic bacteria, a 2.0-log reduction of yeasts and molds, and a 1.5-log reduction of Pseudomonas spp. on cantaloupe surfaces. VSV treatment significantly reduced transfer of yeasts and molds and Pseudomonas spp. from whole cantaloupe surface to fresh-cut pieces during preparation (P < 0.05). Texture and color of the fresh-cut pieces prepared from the VSV-treated whole melons were similar to the controls (Ukuku and others 2006).

An irradiation dose of 1.0 kGy treatment decreased mesophilic bacteria in Mexican salads (Erickson, 2008). However, irradiation can cause changes in pectin structure leading to texture loss and hence shelf life. Also, viruses seem to be relatively resistant to irradiation treatment and relative to vegetative cells, suggesting that doses delivered to inactive... 

These enzymes must have a large activity spectrum, and ideally enantioselectivity for toxic stereoisomers. Their mass production under GMP conditions must be realizable at a reasonable cost. Long-term storage without activity loss (in solution, lyophilized, or adsorbed/bound on a matrix) must be possible under field conditions. Conformational stability can be optimized by chemical modification or addition of stabihzers such as polyols. Thermostable enzymes from thermophilic bacteria (Merone et al., 2005) or mutated/ evolved highly stable enzymes from mesophilic bacteria (Elias et al., 2008) are promising alternatives. 

Table 2 Percentage of charged amino acids and (G - - C) content of 10 hyperthermophilic archaea (A), 2 hyperthermophilic bacteria (B), and mesophilic bacteria E. coli. A strong prevalence of lysine over arginine in proteomes of hyperthermophiles is obtained for nine organisms. A bold font marks the exception from the general trend...

The second feature is that the hydrocarbon chains link to the glycerol moiety exclusively by ether linkages in Archaeal lipids. This is in contrast to the Bacterial polar lipids most of which have ester linkages between the fatty acids and the glycerol residue. From the point of view of simplicity, it seems that mesophilic Bacteria existed before the Archaea since the latter contain more complex lipids. 

It seems that Archaea entered their hot habitats at later phases, after mesophilic, double-membrane bacteria had developed. The term Archaea is misleading as genuine mesophilic Bacteria existed before Archaea. It is also counterintuitive that monolayer bacteria formed from the double-membrane bacteria by losing one membrane.

Novotna et al. (1999) showed that sensory quality of apple juice subjected to high-pressure treatment was better than that of pasteurized juice in terms of aroma. Lavinas et al. (2008) indicated that high-pressure processing (350-400 MPa, 3 or 7 min) of cashew apple juice reduced the aerobic mesophilic bacteria count to a level below the detection limit yeast and filamentous fungi were also inactivated. The juice could be stored for 8 weeks at 4°C without any significant change in the product quality. 

From the viewpoint of bacteriological and biological requirements the permissible indicators involve the quantity of coliform and mesophile bacteria. Of course, drinking water must not contain any pathogens, microscopic and macroscopic organisms which come from waste- or surface waters. The Standard limits the number of infusoria and colourless flagellata. The rated indicators also include the amounts of psychrophile bacteria and enterococci.

In industrial production, a lot of bacteria can be used for the production of CGTase, including aerobic mesophilic bacteria such as B. circulars and B. megaterium, etc, aerobic thermophilic bacteria such as B. stearothermophilus, and anaerobic thermophilic bacteria, such as Thermoanaerobacterium thermosul-furigenes, aerobic alkaliphilic bacteria such as B. circulars, Bacillus fat, and aerobic halophilic bacteria such as halophilic bacilli, etc. The CGTase secreted by most of the microbes are extracellular enzymes, and the yield of the CD and the main product of these enzymes are different, mainly a-CD, fi-CD and y-CD.

Energy conservation via polysulfide sulfur respiration in Bacteria and Archaea appears to be similar. Membrane bound respiratory chains generate a chemios-motic potential, which is utilized by membrane bound ATP synthases to form ATP. Yet, due to their extreme habitats, thermophiles like A. ambivalens and hyperthermophiles like P. abyss may have adapted their electron transport systems to high temperatures by forming stable electron transport complexes in contrast to the mesophilic bacteria W. succinogenes.
