ABSTRACT Minas artisanal cheese is made from endogenous starter cultures, including lactic acid bacteria (LAB). Some LAB may possess probiotic potential. Thus, this study aimed to evaluate the in vitro probiotic properties of lactobacilli isolated from Minas artisanal cheeses produced in Minas Gerais. Ten samples of lactobacilli, formerly isolated from those cheeses, were submitted to the following assays: antimicrobial susceptibility, tolerance to artificial gastric juice and biliary salts, production of hydrogen peroxide and antagonism against pathogenic and non-pathogenic micro-organisms. Only L. plantarum (C0) was sensitive to all tested antimicrobials, while the other LAB samples were resistant to at least one drug. Six samples were tolerant to artificial gastric juice, and L. brevis (A6) even grew in that medium. Three samples were tolerant to biliary salts. Only L. brevis (E35) produced hydrogen peroxide. Difference (P< 0.05) was observed among the means of inhibition haloes of lactobacilli against Enterococcus faecalis ATCC 19433 and Lactobacillus plantarum C24 in spot-on-the-lawn assay. All samples of lactobacilli inhibited Escherichia coli ATCC 25922, Salmonella enterica var. Typhimurium ATCC 14028 in co-culture antagonism test (P< 0.0001). Most lactobacilli samples showed in vitro probiotic potential. From the tested samples, L. brevis (A6) presented the best results considering all in vitro probiotic tests.

Hydrolysis Of

Hydrolysis of 2-chloroethyl palmitate and 2-chloroethyl linoleate was studied in artificial gastric juice, artificial pancreatic juice, pig liver homogenates and pig intestine homogenates. Hydrolytic activity was followed by gas-liquid chromatography. Substantial hydrolysis was observed in all preparations except the artificial gastric juice. Hydrolysis constants ranged from &lt;0.001 min−1 in the gastric juice to 0.064 min−1 for the linoleate ester in the pancreatic juice.

Short Time

By feeding infected flesh to experimental animals, and examining the stomach contents of the latter at varying periods after feeding, various workers have shown that Trichinella larvae are released from their cysts within one or two hours after reaching the stomach of the experimental host. (Bugge, 1934, Heller, 1933, 1934, Kreis, 1937.) The actual release of the larvae from the cysts has not been followed, though Kreis (1937) on the basis of the appearance of stained cysts recovered a short time after ingestion, suggests that the larvae are released not only by the action of the gastric juice of the host, but also as a result of secretory activity by the larvae themselves within the cysts.

Scavenging Rates

In this study, 3 Lactobacillus strains isolated from 5 kinds of traditional fermented yogurt in Xinjiang were identified as Lactobacillus plantarum (LP1, LP2), and Lactobacillus delbrueckii subsp. Bulgaricus (LD). Probiotic properties of Lactobacillus strains have been evaluated by testing the tolerance to artificial gastric juice and bile salt, cell surface hydrophobicity, hydroxyl radicals and DPPH free radicals scavenging rates. As the results, LP1 showed better tolerance to acid, cell surface hydrophobicity and antioxidant ability, LP2 showed better tolerance to bile salt comparing with the other two LAB strains. LP1 showed the best probiotic properties in general. These results provide reference value for the probiotic research in vivo and the development of new functional probiotic products in the future.
