Proposal of six species of moderately thermophilic, acidophilic, endospore-forming bacteria: Alicyclobacillus contaminans sp. nov., Alicyclobacillus fastidiosus sp. nov., Alicyclobacillus kakegawensis sp. nov., Alicyclobacillus macrosporangiidus sp. nov., Alicyclobacillus sacchari sp. nov. and Alicyclobacillus shizuokensis sp. nov.
Moderately thermophilic, acidophilic, spore-forming bacteria (146 strains) were isolated from various beverages and environments. Based on the results of sequence analysis of the hypervariable region of the 16S rRNA gene, eight of the strains represent novel species of the genus Alicyclobacillus. These strains were designated 3-A191(T), 4-A336(T), 5-A83J(T), 5-A167N, 5-A239-2O-A(T), E-8, RB718(...
متن کاملCharacterization of spore germination of a thermoacidophilic spore-forming bacterium, Alicyclobacillus acidoterrestris.
The germination behaviors of spores of Alicyclobacillus acidoterrestris, which has been considered to be a causative microorganism of flat sour type spoilage in acidic beverages, were investigated. The spores of A. acidoterrestris showed efficient germination and outgrowth after heat activation (80 degrees C, 20 min) in Potato dextrose medium (pH 4.0). Further, the spores treated with heat acti...
متن کاملThe Prevalence and Control of Bacillus and Related Spore-Forming Bacteria in the Dairy Industry
Milk produced in udder cells is sterile but due to its high nutrient content, it can be a good growth substrate for contaminating bacteria. The quality of milk is monitored via somatic cell counts and total bacterial counts, with prescribed regulatory limits to ensure quality and safety. Bacterial contaminants can cause disease, or spoilage of milk and its secondary products. Aerobic spore-form...
متن کاملPhylogenetic and spectroscopic analysis of Alicyclobacillus isolates by 16S rDNA sequencing and mid-infrared spectroscopy
Alicyclobacillus spp. are a group of thermophilic, acidophilic, spore-forming bacteria, some of which cause spoilage in commercially pasteurized fruit and vegetable juice products including apple, orange, tomato and carrot juice. In this study, we characterized seven isolates of Alicyclobacillus (14-2, KF, A-Gala 2-1, C-Fuji 6, Gala 9-2, 1016, 18-1) and a reference strain A. acidiphilus DSM 145...
