in this study, the neutral monosaccharide composition of the extracellular polysaccharide (eps), extracted from thermal bacillus, was determined by liquid chromatography-mass spectrometry and high performance liquid chromatography. our analysis indicated that the eps consisted of rhamnose, mannose, galactose, glucose, fructose, arabinose and xylose. in addition to the neutral sugars in the eps,...

Membrane fatty acid composition and thermal resistance (D value) of Pediococcus sp. were determined for mid-exponential-phase (ME) and stationary-phase (ST) cells grown in tryptic soy broth (TSB) and tryptone-glucose-yeast extract (TGY) at 28 and 37 degrees C. As the cells entered the stationary phase of growth, the unsaturated fatty acid, C18:1 n11c, produced during the exponential phase of gr...

In this study, a waterproof material was used to fabricate microcapsule by interfacial curing reaction to encapsulate an alkaliphilic spore-forming bacterium. The technical feasibility of encapsulated spores and the influence of three kinds of curing agent on the calcium precipitation activity (CPA) of the bacterium were studied. Furthermore, micromorphology of microcapsules was observed by Sca...

Background: Leprosy is a chronic disease, caused by the bacterium Mycobacterium leprae. It characterized decrease or loss of thermal, pain and tactile sensitivity, as well muscle strength.

Global change and its associated temperature increase has directly or indirectly changed the distributions of hosts and pathogens, and has affected host immunity, pathogen virulence and growth rates. This has resulted in increased disease in natural plant and animal populations worldwide, including scleractinian corals. While the effects of temperature increase on immunity and pathogen virulenc...

Bacterial spore formers are being used as probiotic supplements for human dietary supplements as well as in registered medicines and for use in animal feeds. Their heat stability and ability to survive the gastric barrier makes them attractive as food supplements and this use is now growing. While often considered soil organisms this conception is misplaced and Bacilli should be considered as g...

The purpose of this work was to obtain heat resistance data relevant to pasteurisation regimes and to model the effects of a range of temperatures (93 to 107°C) and pH (3.6 to 6.4) on the survival of the several Bacillus spp. spores that have been associated with spoilage of foods (Bacillus pumilus, B. licheniformis, B. subtilis, and B. megaterium), and to validate the results obtained by heati...
