Isolation and Identification of 3-(2-Furoyl)alanine andl-Pipecolic Acid from Green Gram Seeds

Isolation, purification, and characterization of pipecolic acid-containing actinomycins, Pip 2, Pip 1 , and Pip 1 .

Streptomyces antibioticus synthesizes several new actinomycins when DL-pipecolic acid is provided in the culture medium. Three of the compounds (Pip 2, Pip lar, and Pip Ifi) were isolated, purified, and characterized. Amino acid hydrolysates revealed that these antibiotics contain threonine, valine, sarcosine, and N-methylvaline but differ from actinomycins normally synthesized in the imino aci...

First isolation and identification of Vibrio vulnificus (biotype 2) from cultured beluga, Huso huso in Iran

By decreasing of sturgeon stocks in the Caspian Sea, the culture of different sturgeon species especially Huso huso was increased in Iran. Under stress conditions sturgeon can easily be infected by several opportunistic pathogens. In June 2011, mortality happened in 25-28°C water temperature, in one of the most important cultured sturgeon farms in Mazandaran province in the north of Iran. The m...

ISOLATION AND IDENTIFICATION OF IRONSULPHUR OXIDZING THIOBACIULLI FROM IRAN ENVRONMENTS

Two hundred samples were taken from various sites in Iran, including coal storage areas, waste water in the Tabas and Zirab coal mines, and sulphur containing acid springs in Ramsar and Abask , and were screened for Thlobacillus ferruuxidans. During this investigation , seven strains were isolated which could oxidize sdphm , pyrite , thiosdphate and ferrous iron as the sole energy source. Macr...

Isolation and identification of halophilicbacteria from Urmia Lake in Iran

Halophiles are in all three domains of life: Archaea, Bacteria and Eucarya. Halophilic microorganisms in addition to form major part of life biodiversity can have many biotechnological applications. The objective of this research is isolation and identification of halophilic bacteria from Urmia Lake in Iran and the study of its bacterial biodiversity. After sampling of brines from Urmia Lake fr...
