ISSN: 1433-4909Keywords: Key words Barophilic bacterium ; Deep sea ; Hydrostatic pressure ; Photobacterium ; Ryukyu TrenchSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract A novel, moderately barophilic bacterium was isolated from a sediment sample obtained from the Ryukyu Trench, at a depth of 5110 m. The isolate, designated strain DSJ4, is a Gram-negative rod capable of growth between 4°C and 18°C under atmospheric pressure, with optimum growth displayed at 10°C, and capable of growth at pressures between 0.1 MPa and 70 MPa at 10°C, with optimum growth displayed at 10 MPa. Strain DSJ4 is a moderately barophilic bacterium, and shows no significant change in growth at pressures up to 50 MPa. Phylogenetic analysis of the 16S rRNA sequence of strain DSJ4 places this strain within the Photobacterium subgroup of the family Vibrionaceae, closely related to the strain SS9 that was independently isolated from the Sulu Trough. The temperature and pressure ranges for growth, cellular fatty acid composition, and assorted physiological and biochemical characteristics indicate that these strains differ from other Photobacterium species. Furthermore, both SS9 and DSJ4 displayed a low level of DNA similarity to other Photobacterium type strains. Based on these differences, these strains are proposed to represent a new deep-sea-type species. The name Photobacterium profundum (JCM10084) is proposed.Type of Medium: Electronic ResourceURL: -

Published 1993Staff ViewISSN: 1438-2199Keywords: Amino acids ; L-Ala ; Bacillus subtilis ; Spore ; Germination ; Alanine racemaseSource: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Summary Germination ofBacillus subtilis spores was initiated by L-Ala and competitively inhibited by D-Ala, suggesting the presence of an alanine receptor. The spores showed alanine racemase activity in the spore coat. To investigate the role of alanine racemase (L → D) on germination, net racemase activity was determined using diphenylamine as a germination inhibitor and germination was measured using D-penicillamine as a racemase inhibitor. Apparent affinity of L-Ala to the germinant receptor was more than 1000 times higher than that to the racemase. Germination increased in the presence of D-penicillamine, when the concentration of L-Ala was low and that of spores was high. Racemase activity was optimal at 65°C at pH 9.0 and germination at 43°C at pH 7.2. Under unfavorable growth conditions such as high population of spores in limited nutrients, high temperature and high pH, spore alanine racemase converted the germinant actively to the inhibitor and this conversion may regulate germination for survival of the population.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-1793Source: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The effects of UV-A and UV-B radiation on photosynthesis of zooxanthellae within the siphonal mantle of the giant clam, Tridacna crocea, and in isolation were studied. While UV-B irradiation (2.4 W m−2, 20 min) completely suppressed photosynthesis of the isolated zooxanthellae, it had little effect on their photosynthetic ability if they were irradiated while within the siphonal mantle of the host tissue. Chemical analysis of the siphonal mantle of T. crocea showed the presence of significant amounts of mycosporine-like amino acids (MAAs), which absorb UV-A and -B light. However, no MAA was detected in the isolated zooxanthellae. MAAs were concentrated in the siphonal mantle and kidney tissues in comparison with other tissues. In the siphonal mantle, MAA concentrations were the highest in the outermost surface layer where most of the zooxanthella cells resided. This indicates that the zooxanthellae are protected from UV radiation by a screen of concentrated MAAs in the host clam. Aside from T. crocea, significant amounts of MAAs were found not only in other zooxanthellate clams, such as T. derasa, Hippopus hippopus, Colculum cardissa and Fragum unedo, but also in a closely related azooxanthellate clam, Vasticardium subrugosum. On the other hand, no MAA was detected in any of the zooxanthellae from these zooxanthellate clams. No MAA was detected in the tissues of a deep-sea bivalve, Calyptogena soyoae. Although MAAs seem to block strong UV radiation in the shallow-water clam, they are probably not essential for the clam's life in the dark. MAAs in shallow-water clams may be derived from food and accumulated in their tissues, especially in the siphonal mantle and kidney.Type of Medium: Electronic ResourceURL: -

ISSN: 1432-072XKeywords: Key wordsThermococcus peptonophilus ; Deep-sea ; Hydrothermal vents ; Survival ; Extreme thermophiles ; Culturability ; Active cells ; Mortality ; Dead cellsSource: Springer Online Journal Archives 1860-2000Topics: BiologyNotes: Abstract The culturability of a strictly anaerobic, extremely thermophilic archaeon, Thermococcus peptonophilus (optimal growth temperature: 85° C), was studied during survival stages at various temperatures (98, 85, 70, and 4° C). Total cell number (determined by DAPI staining), active cells (rhodamine-stained cells), and culturable cells (using most-probable-number) were counted over time. The number of culturable cells decreased under each condition tested. The total number of cells significantly decreased only at temperatures close to the maximum for growth (98° C); at this temperature, the cells spontaneously lysed. Our results suggested that survival at 4° C in oxygenated waters might be a mechanism for the dispersion of extreme thermophiles in the ocean. In addition, we proved the existence of T. peptonophilus cells in several physiological states: culturable cells, active non-culturable cells, inactive non-culturable cells, and dead cells. Cell death was caused by cellular lysis.Type of Medium: Electronic ResourceURL:
