Distribution of thermophilic aerobic sporeforming bacteria in food ingredients.
Samples of sugar, starch, spices, and miscellaneous products were tested for thermophilic sporeformers of Bacillus to determine the dominant species present. Surface colonies selected at random were identified. Six species of Bacillus were isolated: B. stearothermophilus, B. coagulans, B. licheniformis, B. subtilis, B. circulans, and B. pumilus. Samples of starch and pepper were tested for ther...
متن کاملIsolation and characterization of aerobic thermophilic bacteria from the savusavu hot springs in fiji.
The relative isolation and unique physical properties of the Savusavu Hot Springs in Fiji may yield unique thermophiles. This study was conducted to determine the presence of aerobic thermophilic bacteria in these hot springs. A total of 104 thermophilic bacterial isolates were characterized and using Thermus and Bacillus strains as controls, 58% of the isolates were identified as Anoxybacillus...
متن کاملHeat Activation Inducing Germination in the Spores of Thermotolerant and Thermophilic Aerobic Bacteria.
Relatively mild heating of the spores of mesophilic aerobes has been shown to hasten their subsequent germination (Evans and Curran, 1943). Although effective in bringing about a more rapid germination, with one exception, such heating had no measurable influence upon the number of spores that germinated. This tangible evidence of pregermination stimulation led us to extend our observations to ...
متن کاملThermophilic mixed culture of bacteria utilizing methanol for growth.
A thermophilic mixed population of bacteria, capable of utilizing methanol as its sole carbon-energy source at temperatures up to 65 C, was selected by enrichment and studied. A maximal cellular yield of 0.42 g per g of methanol was observed at 50 to 56 C. The maximal specific growth rate of the mixed population in continuous culture at 56 C was greater than 0.32 per h. The amino acid profile o...
متن کاملThe effect of oxygen on the growth and metabolism of the aerobic thermophilic actinomycete Micromonospora vulgaris.
In the presence of pure oxygen at one atmosphere pressure Micromonospora vulgaris is unable to form in liquid media a surface pellicle of growth-bearing aerial mycelium. The production of bottom growth is either unaffected or stimulated by oxygen. Vegetative mycelium which develops from spores in Warburg vessels has an oxygen uptake that is similar in the presence of air or oxygen. Aerial mycel...
