“…According to the said study, Weissella kimchi did not produce harmful metabolites or enzyme and hence was considered as a ppotential probiotic for vaginal health. Others have also hinted that Weissella confusa strains are excellent probiotic agents and require application studies [18]. In the said study, Weissella confusa 20 showed a very high adherence to the caco-2 cells even better than Lactobacillus rhamnasus GG.…”

Abstract-Weissella confusa, a lactic acid producing bacteria (LAB), is known to occur in the human samples of breast milk, vaginal fluids, saliva and faeces. The species is known to be a probiotic microorganism due to its ability to control the growth of the pathogenic microbes capable of causing food borne diseases. The isolate reported in this study showed high antimicrobial activity against Bacillus subtilis (MTCC 736), Escherichia coli (MTCC 9492), Pseudomonas aeruginosa (MTCC 3541), Proteus mirabilis (MTCC 425), Proteus vulgeris (MTCC 771) and Staphylococcus aureus (MTCC 3160). Additionally, the isolated microbe was resistant to many of the commonly used antibiotics and hence can be used to develop formulations. Thus, the isolated organism may be explored as a probiotic candidate by local administration via suppositories for the prevention and treatment of vaginal infections.

Analysis of 16S rRNA Gene of Lactic Acid Bacteria Isolated from Curd and Raw Milk

Rawmilk and curdsamples from various dairy outlets in the city were collected and putative lactic acid bacteria were isolated on MRS agar. These were first screened using preliminary criteria and then identified by analysing the 16S rRNA gene. For the molecular identification, extraction and quantification of bacterial DNA was first performed and the isolated DNA was amplified by PCR. This PCR product was then purified and sequenced using specific primers. The DNA sequences were then analysed using BLASTn and the results were used to generate a phylogenetic tree. From a total of four samples of curd and six samples of raw milk, the organisms identified were Lactobacillus fermentum in all the four samples of curd and one sample of raw milk. The rest of the five samples of raw milk showed two of the isolates to be Weisella confusa (basonym Lactobacillus confusus) and three to be Weisella cibaria.

“…Several studies have demonstrated the probiotic potential of Weissella confusa, its antimicrobial activity against pathogenic microorganisms, including Helicobacter pylori (Nam et al, 2002), Staphylococcus aureus, Streptococcus agalactiae, Escherichia coli, Klebsiella pneumonic (Serna-Cock et al, 2012), and its ability to adhere itself to the vaginal and intestinal epitheliums (Ayeni et al, 2011;Lee et al, 2012). In the food probiotics, processing is important; the concentration of probiotic bacteria (WHO / FAO, 2006), and the techniques are used to maintain their viability (Carvalho et al, 2004).…”

The effects of wall materials and encapsulation by lyophilization on the viability of Weissella confusa were evaluated. Aloe vera gel, sodium casein at 5 and 15% p/v, sodium alginate at 2% p/v, buffer phosphate, and a mixture (Aloe vera gel, sodium casein, and sodium alginate) as wall materials, were used. Bacteria without encapsulation (W. confusa) as control were used. Encapsulated bacteria were freeze dried for 48 h, in order to determine their viability in the freezing and sublimation-drying stages. Results indicate that bacteria without encapsulation, showed greater loss of viability in the sublimationdrying stage. All the wall materials evaluated, may be used for encapsulation of bacteria, because, at the end of the freeze-drying process, the encapsulated bacteria showed higher viability percentages than non-encapsulated bacteria, with significant statistical difference (p<0.05). The protective effect of wall materials was higher in the sublimation-drying stage, compared to freezing stage.
