Isolation and characterization ofLactococcus garvieae from diseased rainbow trout (Oncorhynchus mykiss, Walbaum) cultured in Iran
A total of 200 moribund rainbow trout with clinical signs of a hyperacute haemorrhagic septicemia were collected from rainbow trout farms in Fars, Kohkiloyeh-Boyer Ahmad and Charmohal-Bakhtiari provinces in the south and southwest of Iran during summer 2002 to winter 2008 for detection of Lactococcus garvieae, the causative agent of lactococcosis. Fish kidney samples were cultured aseptically o...
متن کاملIsolation and characterization of Lactococcus lactis subsp. lactis promoters.
DNA fragments with promoter activity were isolated from the chromosome of Lactococcus lactis subsp. lactis. For the isolation, a promoter probe vector based on the cat gene was constructed, which allowed direct selection with chloramphenicol in Bacillus subtilis and L. lactis. Four of the putative promoters (P1, P2, P10, and P21) were analyzed further by sequencing, mapping of the 5' end of the...
متن کاملPhysicochemical and functional characterization of a biosurfactant produced by Lactococcus lactis 53.
Isolation and identification of key components of the crude biosurfactant produced by Lactococcus lactis 53 was studied. Fractionation was achieved by hydrophobic interaction chromatography which allowed the isolation of a fraction rich in glycoproteins. Molecular (by Fourier transform infrared spectroscopy) and elemental compositions (by X-ray photoelectron spectroscopy) were determined. Criti...
