Huang C, Garcia J, Patel B, Cayol J, Baresi L, Mah R
Int J Syst Evol Microbiol . 2000 Apr; 50 Pt 2:615-622. PMID: 10758867
Strain DVT, a halotolerant, Gram-negative, facultatively anaerobic bacterium, was isolated from a hypersaline pond located in Death Valley, California. The cells were non-spore-forming, motile, curved rods (1.0-1.8 x 0.5-0.6 microns)...

Huang C, Patel B, Mah R, Baresi L
Int J Syst Bacteriol . 1998 May; 48 Pt 1:91-7. PMID: 9542080
An anaerobic, extremely thermophilic, xylanolytic, non-spore-forming bacterium was isolated from a sediment sample taken from Owens Lake, California, and designated strain OLT (T = type strain). Strain OLT had a...

Patel B, Andrews K, Ollivier B, Mah R, Garcia J
FEMS Microbiol Lett . 1995 Dec; 134(1):115-9. PMID: 8593948
The 16S rRNA gene (rDNA) sequence analysis of four halophilic anaerobes: Halobacteroides halobius, H. lacunaris. Haloanaerobacter (Hb.) chitinovorans and H. acetoethylicus confirmed that they were all members of the family...

Tsai C, Garcia J, Patel B, Cayol J, Baresi L, Mah R
Int J Syst Bacteriol . 1995 Apr; 45(2):301-7. PMID: 7537063
A strictly anaerobic, moderately halophilic, gram-negative, rod-shaped bacterium was isolated from Great Salt Lake, Utah, sediments and designated GSLST (T = type strain). Strain GSLST grew optimally at pH 6.7...

Ollivier B, Caumette P, Garcia J, Mah R
Microbiol Rev . 1994 Mar; 58(1):27-38. PMID: 8177169
Strictly anaerobic halophiles, namely fermentative, sulfate-reducing, homoacetogenic, phototrophic, and methanogenic bacteria are involved in the oxidation of organic carbon in hypersaline environments. To date, six anaerobic fermentative genera, containing nine...

Liaw H, Mah R
Appl Environ Microbiol . 1992 Jan; 58(1):260-6. PMID: 16348626
Two halophilic anaerobic bacteria, one of which had chitinolytic activity, were isolated from a solar saltern in southern California. These organisms were long, gram-negative, motile, flexible rods. The biochemical and...

Xun L, Mah R, Boone D
Appl Environ Microbiol . 1990 Dec; 56(12):3693-8. PMID: 2082820
At certain stages in its growth cycle, Methanosarcina mazei produces an enzyme (disaggregatase) that causes aggregates to separate into single cells. M. mazei S-6 and LYC both produce this enzymatic...

Westermann P, Ahring B, Mah R
Appl Environ Microbiol . 1989 Sep; 55(9):2257-61. PMID: 16348006
Methanosarcina barkeri MS and 227 and Methanosarcina mazei S-6 produced acetate when grown on H(2)-CO(2), methanol, or trimethylamine. Marked differences in acetate production by the two bacterial species were found,...

Westermann P, Ahring B, Mah R
Appl Environ Microbiol . 1989 May; 55(5):1262-6. PMID: 16347915
The affinity of Methanosarcina barkeri 227 for acetate and hydrogen at different incubation temperatures was investigated. Increasing the temperature from 20 to 37 degrees C resulted in a 4.5-fold increase...

Westermann P, Ahring B, Mah R
Appl Environ Microbiol . 1989 Feb; 55(2):514-5. PMID: 16347858
Marked differences were found for minimum threshold concentrations of acetate catabolism by Methanosarcina barkeri 227 (1.180 mM), Methanosarcina mazei S-6 (0.396 mM), and a Methanothrix sp. (0.069 mM). This indicates...
