Title: ¦Å-poly-lysine to produce a strain screening
Abstract: collected many soil samples as a screening source system for a series of studies on the ¦Å-poly-L-lysine producing strain, and filter out the bacteria were separated and identified, to be isolated with higher yield of ¦Å-poly-lysine producing bacterium.
Collection back soil samples were enriched and then used to inoculate the screen than the enrichment the easier to get bacteria. In this study, the SG medium (liquid) were enriched. SG medium with methylene blue and potassium dichromate for screening bacteria produce alkali transparent circle the size of the screening, rescreening Dr testing and methyl orange test, the elect are positive bacteria. Screening strains in shake flask fermentation test to detect the absorbance standard curve, select a higher yield of several bacteria. Screening out bacteria strains morphological characteristics, cultural characteristics and physiological and biochemical characteristics, 16SrDNA gene sequences for research and analysis. Control literature, to classify, filter out bacteria named.
Key words: the ¦Å-polylysine; strain selection; strain identification; fermentation
