Lactobacillus acidophilus 88 produced a bacteriocin, designated lactacin F, that demonstrated inhibitory activity toward L. acidophilus 6032, L. lactis 970, L. helveticus 87, L. bulgaricus 1489, L. leichmanii 4797, L. fermentum 1750, and Streptococcus faecalis 19433. Production of lactacin F was pH dependent and could be maximized in MRS broth cultures maintained at pH 7.0. Lactacin F was heat ...

Abstract This study was designed to evaluate the bioactivities such as ?-glucosidase activity, ?-galactosidase and growth behavior of Lactobacillus cultures in soy milk medium. Ten were considered this study. L. fermentum (M2) casei (NK9) selected due their better ?-galactosidase, activity medium during fermentation. Further, fermented with M2 showed higher proteolytic (0.67 OD) ACE-inhibitory ...

Our previous analysis of 65 advanced dental caries lesions by traditional culture techniques indicated that lactobacilli were numerous in the advancing front of the progressive lesion. Production of organic acids by lactobacilli is considered to be important in causing decalcification of the dentinal matrix. The present study was undertaken to define more precisely the diversity of lactobacilli...

In this study, nineteen Lactobacillus isolated from Algerian goat’s milk, 13 belonging to L. plantarum, three to L. pentosus, two to L. rhamnosus and one to L. fermentum, were examined in vitro in order to be used as adjunct culture in dairy products. The strains were tested for their proteolytic activity, sensory and safety properties. Strains LbMS16 and LbMS21 L. plantarum and LbMF25 L. rhamn...

Mother milk is a complete food for the child. It contains vital nutrients and biomolecules required growth development of mainly carbohydrates, proteins, fats minerals. Recently, it was also found that certain different microorganisms which play role in body. Most microorganism belongs to Lactobacilli family. Knowing importance health, industries have focused on these be used as health suppleme...

Lactic acid bacteria (LAB) play important roles in silage fermentation, which depends on the production of sufficient organic acids to inhibit the growth of undesirable microorganisms. However, LAB are not able to degrade cellulose and hemicellulose. Bacteria and fibrolytic enzymes are usually used as inoculants to improve the silage quality and digestibility. In the present study, we isolated ...

Lactobacillus fermentum NCC2970 (CNCM I-5068) is a lactic acid bacterium originating from the Nestle Culture Collection. Here, we disclose its full 1.9-Gb genome sequence comprising one chromosome with no plasmid.

Abstract In the study, four potent Lactobacillus cultures of L. rhamnosus K4E, plantarum RD7, fermentum K7, and K16 were considered for production B-vitamins, organic acids biotransformation soy isoflavones. RD7 showed highest B 2 (0.84 μg mL −1 ) after 36 h, while exhibited maximum 12 (0.084 h. K4E produced 0.24 folate Highest lactate (16.43 acetate (5.86 was reported by K4E. butyrate (0.253 c...
