Transformation of Lactobacillus acidophilus with Hygromycin Gene Originated from Streptomyces hygroscopicus
To Investigate the ability of Streptomyces isolate to produce hygromycin B antibiotic as antithelmantic agent in poultry feed and selecting a suitable expression vector encoded hygromycin B phosphotransferase resistance gene and transforming Lactobacillus isolateby electroporation , from a total of 53 Streptomyces isolates, DNA was extracted and screened for the presence of hygomycin B gene using specific designed primer sets in Polymerase Chain Reaction (PCR) technique. Only three of the isolates were positive for the existence of such a gene which
