In our study, the sample (cheese) was selected for isolation and identification of Lactobacillus species as local probiotic isolate. The strain was subjected to microscopic and macroscopic investigations for probiotic selection. The world health organization criteria (WHO) were applied to all Lactobacillus species against E. coli, P. areoginosa, S. aerus, Chromobacterium, Serratia and A. flavus...

Lactobacillus plantarum strain B21 was isolated from Vietnamese sausage (nem chua) and demonstrated broad antimicrobial activity due to the production of bacteriocins. Here, we report the complete genome sequence of this strain (3,284,260 bp).

The esential role of -glutamine in microbial nutrition and metabolism has been well established (Waelsch, 1952). Recently Ayengar et al. (1951) have described in detail the stimulating effect of the amide on the utilization of i-glutamic acid by Lactobacillus arabinosus. However, almost no published data exist which deal with the influence of iisoglutamine on bacterial growth. We wish to descri...

This study aimed to isolate and identify Lactobacillus in the honey stomach of honeybee Apis dorsata. Samples of honeybee were collected from A. dorsata colonies in different bee trees and Lactobacillus bacteria isolated from honey stomachs. Ninety two isolates were Gram-stained and tested for catalase reaction. By using bacterial universal primers, the 16S rDNA gene from DNA of bacterial colon...

The influence of pH on the type and concentration of metabolites produced from pyruvate by Lactobacillus plantarum ATCC 8014 was examined in pH-controlled fermentors at pH values of 4.5 to 6.5. Specific growth rates, cell dry weights, and diacetyl concentrations were highest at pH 5.5, with values of 0.78 h, 190 mg/liter, and 1.2 mM, respectively. While the conversion efficiency (millimoles of ...

Excess cholesterol is associated with cardiovascular diseases (CVD), an important cause of mortality worldwide. Current CVD therapeutic measures, lifestyle and dietary interventions, and pharmaceutical agents for regulating cholesterol levels are inadequate. Probiotic bacteria have demonstrated potential to lower cholesterol levels by different mechanisms, including bile salt hydrolase activity...

Eighteen strains of Lactobacillus plantarum from different origins were screened for carotenoid production, as many of them exhibited a deep yellow pigmentation when cultured as isolated colonies on MRS-agar plates. We found that most of them produced significative amounts of the yellow C(30) carotenoid 4,4'-diaponeurosporene in the range 1.8 to 54 mg/kg of dry cell weight. Although some of the...
