Clostridium alkalicellum sp. nov., an Obligately Alkaliphilic Cellulolytic Bacterium from a Soda Lake in the Baikal Region

The first anaerobic alkaliphilic cellulolytic microorganism has been isolated from the Verkhnee Beloe soda lake (Buryatiya, Russia) with pH 10.2 and a salt content of up to 24 g/l and proposed as a new species: Clostridium alkalicellum sp.

Haloanaerobium lacusroseus sp. nov., an extremely halophilic fermentative bacterium from the sediments of a hypersaline lake.

This organism was a sluggishly motile, rod-shaped, non-spore-forming, gram-negative, obligate anaerobe that grew optimally at 40 degrees C in the presence of 180 to 200 g of NaCl per liter.

Haloanaerobium alcaliphilum sp. nov., an anaerobic moderate halophile from the sediments of Great Salt Lake, Utah.

The16S rRNA gene sequence of strain GSLST was found to be similar to, but also significantly different from, the 16S r RNA sequences of Haloanaerobium salsugo and Haloanaers praevalens, therefore, strain GSL ST is described as a new species, Haloanaingobium alcaliphilum.

Haloincola saccharolytica subsp. senegalensis subsp. nov., Isolated from the Sediments of a Hypersaline Lake, and Emended Description of Haloincola saccharolytica

A new halophilic chemoorganotrophic bacterium related to Haloiizcola sacclzarolytica was isolated from the hypersaline sediments of Retba Lake in Senegal and exhibited marked phenotypic differences, particularly in the range of substrates used, when it was compared with the type species of the genus Haloincola.

Cellulase activity of a haloalkaliphilic anaerobic bacterium, strain Z-7026

SummaryThe cellulolytic activity of an alkaliphilic obligate anaerobic bacterium, Z-7026, which was isolated from the microbial community of soda-lake sediments and belongs to the cluster III of

Haloanaerobium congolense sp. nov., an anaerobic, moderately halophilic, thiosulfate- and sulfur-reducing bacterium from an African oil field.

A strictly anaerobic, moderately halophilic, Gram-negative, non-motile rod-shaped bacterium was isolated from an oil-well head sample of an offshore Congolese oil field and Ribosomal 16S rRNA sequence analysis showed that strain SEBR 4224T is a new member of the genus Haloanaerobium.

Haloanaerobacter salinarius sp. nov., a novel halophilic fermentative bacterium that reduces glycine-betaine to trimethylamine with hydrogen or serine as electron donors; emendation of the genus Haloanaerobacter.

Strain SG 3903T, a novel halophilic fermentative bacterium isolated from the black sediment below a gypsum crust and a microbial mat in hypersaline ponds of Mediterranean salterns, represents the first described strain in the genus Haloanaerobacter capable of the Stickland reaction with two amino acids.

Hcdocincierobizm congolense sp . nov . , an anaerobic , moderately halophilic , thio Sulfat e-and sulfur-I : educing b act eriuin from an African oil field

X strictly anaerobic, moderately halophilic. Gram-negative. non-motile rod-shaped bacterium was isolated from an oil-well heod sample ot' an ofi'shore Congolese oil field. The strain. designated SEBR



Halophilic and halotolerant microorganisms‐an overview and historical perspective

It seems appropriate to base an introduction on an illustration depicting a rough grouping of the microorganisms we are about to discuss into types on the basis of their ability to grow and


Taxonomic studies on methylotrophic bacteria by 5S ribosomal RNA sequencing.

Nucleotide sequences of 5S ribosomal RNA isolated from 19 strains of Gram-negative methylotrophic bacteria showed that the bacteria analysed belong to the Proteobacteria and fell into several clusters, including obligate methanotrophics, obligate methylotrophs and several groups of facultative methylotophs.

Bacteria in the Bottom Sediments of the Dead Sea

IN order to investigate the presence of different physiological groups of bacteria in the different layers of the bottom sediments of the Dead Sea1,2,3, it was essential to obtain profiles of mud

The quantitative measurement of DNA hybridization from renaturation rates.

A new method is proposed to measure relatedness amongst bacteria, based on renaturation rate determinations of DNA types and their mixture, and the advantages are summarized.
