Marine ornamental fishes are remarkably valuable due to their high demand in domestic and international markets. It is a growing global interest to maintain these fishes in captivity. The bacterial and fungal infection is the major drawbacks in captive condition. In the present study, in-vitro screening of organic solvent extracts (methanol and acetone) of green algae Halimeda micronesia were t...

Phylogenetic estimation method without determination of DNA sequence was developed. By this method, fragment length polymorphism separately digested with multiple restriction enzymes was measured using microchip electrophoresis and affiliated with those calculated from corresponding DNA sequence in the theoretical database. The phylogenies of 129 NO(3)(-) reducing bacteria newly isolated from f...

We recently isolated Micrococcus sp. strain 2385 from Ochlockonee River, Florida and demonstrated potent biodegradative activity against two commonly used pesticides- alachlor [(2-chloro-2`,6`-diethylphenyl-N (methoxymethyl)acetanilide)] and endosulfan [(6,7,8,9,10,10-hexachloro-1,5,5a,6,9,9a-hexahydro-6,9methano-2,3,4-benzo(e)di-oxathiepin-3-oxide], respectively. To further identify the repert...

Physiological age-dependent variation in radiation resistance was studied for three bacteria that are highly radiation resistant: Micrococcus radiodurans, Micrococcus sp. isolate C-3, and Moraxella sp. isolate 4. Stationary-phase cultures of M. radiodurans and isolate C-3 were much more resistant to gamma radiation than were log-phase cultures. This pattern of relative resistance was reversed f...

New two nano- sized Schiff base complexes [M(L)], where L= 2, 2'-((1E, 1E')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and M=Cu or Zn, (a, b complexes) were synthesized by ultrasonic irradiation. These complexes were characterized by elemental analysis, molar conductivity, FT-IR, fluorescence emission, 1H NMR, field emission scanning electron spectroscopy...

Phenol, p-cresol, and volatile fatty acids (VFA; acetic, propionic, isobutyric, butyric, isovaleric, and valeric acids) were used as odor indicators of swine waste. Aeration of the waste allowed the indigenous microorganisms to grow and degrade these malodorous substances. The time required for degradation of these substances varied according to the waste used, and it was not necessarily relate...

The role of cytidine diphosphate (CDP)-glycerol in gram-positive bacteria whose walls lack poly(glycerol phosphate) was investigated. Membrane preparations from Staphylococcus aureus H, Bacillus subtilis W23, and Micrococcus sp. 2102 catalyzed the incorporation of glycerol phosphate residues from radioactive CDP-glycerol into a water-soluble polymer. In toluenized cells of Micrococcus sp. 2102,...

various physico chemical characteristics of the river ganga in varanasi were studied in the oct 2005 to nov 2006. ecological parameters like dissolved oxygen(do), ph, nitrate(no3-), po43- and bacterial population were analyzed and compared with standard permissible limits to assess the best designated use of the river water for various purposes. study revealed that the water quality at varanasi...
