A Gram-positive, rod-shaped, strictly aerobic, spore-forming, moderately halophilic bacterium, designated strain SSK2-2T, was isolated from fermented shrimp paste (ka-pi) produced in Thailand. It contained MK-7 as the predominant menaquinone and meso-diaminopimelic acid in the cell-wall peptidoglycan. The isolate grew at 8-43 degrees C, pH 6-9 and in(More)
Fifteen strains of extremely halophilic bacteria were isolated from fish sauce (nam-pla) collected in Thailand at various stages of the fish-fermentation process. The isolates were strictly aerobic, spore-forming, Gram-positive rods. They grew optimally in the presence of 20-26 % NaCl. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The(More)
Eight strains of aerobic, spore-forming, Gram-positive, moderately halophilic bacteria were isolated from sauce (nam-pla and bu-du) produced in Thailand by the fermentation of fish. They grew optimally in the presence of 10 % NaCl, at 37 degrees C and pH 7.0. A diagnostic diamino acid, meso-diaminopimelic acid, was present in the cell-wall peptidoglycan.(More)
A Gram-positive, spore-forming and moderately halophilic bacterium was isolated from fermented fish (pla-ra) in Thailand. Cells of the isolate, RBU1-1(T), were strictly aerobic, motile rods and contained meso-diaminopimelic acid in the cell-wall peptidoglycan. Menaquinone with seven isoprene units (MK-7) was the predominant quinone. This isolate grew at(More)
Fifteen strains of red-pigmented, strictly aerobic, coccoid, extremely halophilic archaea were isolated from fish sauce (nam-pla) produced in Thailand. They grew optimally at 37 degrees C, pH 6-8 and in the presence of 20-30 % (w/v) NaCl. The DNA G+C contents of the isolates were 60.0-61.8 mol%. They had MK-8(H2) as a major menaquinone component and(More)
Interactions between the protease (PR) encoded by the xenotropic murine leukemia virus-related virus and a number of potential inhibitors have been investigated by biochemical and structural techniques. It was observed that several inhibitors used clinically against HIV PR exhibit nanomolar or even subnanomolar values of K(i) , depending on the exact(More)
Two red-pigmented, strictly aerobic, pleomorphic rod-shaped and extremely halophilic archaea, designated strains HST01-2R(T) and HST03(T), were isolated from salt in a fish sauce sample from Thailand. The novel strains grew optimally at 37 °C, pH 7.0, and in the presence of 20-25 % (w/v) NaCl. The DNA G+C contents of the isolates were 61.6-62.2 mol%.(More)
In order to find a unique proteinase, proteinase-producing bacteria were screened from fish sauce in Thailand. An isolated moderately halophilic bacterium was classified and named Filobacillus sp. RF2-5. The molecular weight of the purified enzyme was estimated to be 49 kDa. The enzyme showed the highest activity at 60 degrees C and pH 10-11 under 10% NaCl,(More)
A halophilic bacterium was isolated from fish sauce, classified, and named Halobacillus sp. SR5-3. A purified 43-kDa proteinase produced by this bacterium showed optimal activity at 50 degrees C and pH 9-10 in 20% NaCl. The activity of the enzyme was enhanced about 2.5-fold by the addition of 20-35% NaCl, and the enzyme was highly stabilized by NaCl. It was(More)
