Aerobic endospore-forming bacteria from geothermal environments in northern Victoria Land, Antarctica, and Candlemas Island, South Sandwich archipelago, with the proposal of Bacillus fumarioli sp. nov.

چکیده
Aerobic endospore-forming bacteria were isolated from soils taken from active fumaroles on Mount Rittmann and Mount Melbourne in northern Victoria Land, Antarctica, and from active and inactive fumaroles on Candlemas Island, South Sandwich archipelago. The Mt Rittmann and Mt Melbourne soils yielded a dominant, moderately thermophilic and acidophilic, aerobic endospore-former growing at pH 5.5 and 50 degrees C, and further strains of the same organism were isolated from a cold, dead fumarole at Clinker Gulch, Candlemas Island. Amplified rDNA restriction analysis, SDS-PAGE and routine phenotypic tests show that the Candlemas Island isolates are not distinguishable from the Mt Rittmann strains, although the two sites are 5600 km apart, and 16S rDNA sequence comparisons and DNA relatedness data support the proposal of a new species, Bacillus fumarioli, the type strain of which is LMG 17489T.

Bacillus luciferensis sp. nov., from volcanic soil on Candlemas Island, South Sandwich archipelago.
Aerobic, endospore-forming bacteria were found in soil taken from an active fumarole on Lucifer Hill, Candlemas Island, South Sandwich archipelago. Amplified rDNA restriction analysis, SDS-PAGE, repetitive element primed-PCR (rep-PCR) and routine phenotypic tests suggested that six of the isolates represent a novel taxon, and 16S rDNA sequence comparisons support the proposal of a novel species...
متن کاملAnoxybacillus contaminans sp. nov. and Bacillus gelatini sp. nov., isolated from contaminated gelatin batches.
Aerobic, endospore-forming bacteria that are attributed to the genus Bacillus or related genera constitute a hazard to the quality of gelatin. During repetitive extragenic palindromic DNA (rep)-PCR screening of gelatin isolates, a group of five isolates (group 1) and a group of 66 isolates (group 2) that did not match any pattern in our database were found. On the basis of 16S rDNA sequence ana...

متن کاملProposal 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(...
