  • Primary Evaluation of the Cold Shock Protein Existing in the Strain Lactobacillus Plantarum Ul497 and the Strain’s Survival after Temperature Downshock

    • Authors: Uyen, Nguyen Quynh; Lan, Thuong Thị Vo;  Advisor: Viện Công nghệ Sinh học, Đại học quốc gia Ha noi; 2VNU University of Science, Vietnam National University, Hanoi, Vietnam (2018)

  • Lactic Acid Bacteria (LAB) have been approved by FDA as GRAS (Generally Recognized as Safe). Among LAB, Lactobacillus plantarum along with other species in the genus Lactobacillus shows its roles in many fields, especially in the food industry. In this study, the deduced amino acids of cold shock protein (Csp) in the strain Lactobacillus plantarum UL497 were compared with those of the reported cold shock proteins, including CspL, CspC and CspP of Lactobacillus plantarum NC8. Then, after freezing, the survival of the bacteria with temperature downshift from 30°C to 8°C for 2, 5 and 8 hours at the growing log phase was determined. In particular, after freezing, the survival percentage o...

  • Primary study on the bacterial strain UL485 isolated from Chao in Hue province, Vietnam

    • Authors: Dao, Anh Thi Nguyen; Hue, Thanh Thi Luu; Thai, Van Hoang; Quyen, minh Huynh Nguyen; Uyen, Quynh Nguyen;  Advisor: Viện Công nghệ Sinh học, Đại học quốc gia Ha noi; Quality Assurance Department, Ha Noi, Viet Nam SunBiozyms Biotechnology Factory (2018)

  • Lactic acid bacteria (LAB) have been applied in many fields like food industry, pharmacy and medicine due to their valuable properties such as the ability to secret some bioactive compounds including organic acids, exopolysaccharides and bacteriocins. In this study, the identification and the nucleotide sequences of plnA and plnEF genes of a LAB strain isolated from the fermented tofu “chao” in Hue province (Vietnam) were studied. In particular, the strain was identified as Lactobacillus plantarum and the sequences of the plnA and plnEF genes were 95% and 98% identical to those of L. plantarum subsp. plantarum strain E1 on the GenBank, respectively.
