PHÂN LẬP, TUYỂN CHỌN VI KHUẨN LACTIC VÀ ỨNG DỤNG TRONG LÊN MEN NEM CHUA NẤM RƠM (Volvariella volvacea)Trần Hân

2020

This study was conducted to isolate lactic acid bacteria l strains and test ed the production of fermented Volvariella volvacea mushroom. L actic acid bacteria l strains were isolated and tested for fermentation ability in MRS b roth medium as well as screened for lactic acid fermentation of V. volvacea mushroom. Fermentation conditions were conducted with different initial cell co n centrations (10 3 , 10 5 , 10 7 cells/g ) and fermentation temperature s (30 °C, 37 °C and environmental temperature 28- 3 2 °C ). As a result, 20 bacterial strains were isolated from 6 samples of Nem chua (Vietnamese fermented pork roll). These bacteria l strains are Gram-positive, rod-shaped, non-spore-forming, and nonmobile. Among these bacterial strains, 10 strains ha d good fermentation ability in MRS b roth supplemented with 20 g/L of D- g lucose including TX61, HCGT31, HK162, L54, L7, HK221, L39, HCM2, TX3, and L30 with the lactic acid concentrations of 10 . 5-21 .0 g/L. T he HCM2 strain, identif...
