Title: Screening,Isolation and Identification of the Segregated Bacterial Strain of Livestock's Hemoglobin
Abstract: The paper isolates and screens 16 bacterial strains from the soil not used for many years but contaminated by discarded poultry's blood.According to protein hydrolysis and the size of ratio on the albumen in junket / gelatin plateform,we confirmed 8 bacterial strains.After a separate 72-hour fermentation of these bacterial strains in the Hb fermented culture solution,we determined their protease activity,dissociated amino acid content,soluble protein content and Hb degrading ratio,and finally singled out a strain(Number: Lact5.Ⅲ),which is the best bacterial strain among the 16.This bacterial strain wass identified to belong to Bacillus cereus through the shape of the colony,determination physiology and biochemistry.
