“…This is simply because juveniles’ diet in captivity is fermented milk, steamed bread, bamboo shoot, and leaves [ 4 , 40 ]. Streptococcus thermophilus comes from fermented dairy products, e.g., fermented milk [ 19 ]. Here we demonstrate that Streptococcus’ addition as a probiotic in geriatrics diet that showed a reduced abundance of Streptococcus (Additional file 1 : Fig.…”

Background The gut microbiome is essential for the host’s health and serves as an essential reservoir of antibiotic resistance genes (ARGs). We investigated the effects of different factors, including the dietary shifts and age, on the functional characteristics of the giant panda’s gut microbiome (GPs) through shotgun metagenome sequencing. We explored the association between gut bacterial genera and ARGs within the gut based on network analysis. Results Fecal samples (n=60) from captive juvenile, adult, and geriatric GPs were processed, and variations were identified in the gut microbiome according to different ages, the abundance of novel ARGs and the biosynthesis of antibiotics. Among 667 ARGs identified, nine from the top ten ARGs had a higher abundance in juveniles. For 102 ARGs against bacteria, a co-occurrence pattern revealed a positive association for predominant ARGs with Streptococcus. A comparative KEGG pathways analysis revealed an abundant biosynthesis of antibiotics among three different groups of GPs, where it was more significantly observed in the juvenile group. A co-occurrence pattern further revealed a positive association for the top ten ARGs, biosynthesis of antibiotics, and metabolic pathways. Conclusion Gut of GPs serve as a reservoir for novel ARGs and biosynthesis of antibiotics. Dietary changes and age may influence the gut microbiome’s functional characteristics; however, it needs further studies to ascertain the study outcomes.

“…Escherichia and Streptococcus are the predominant members of the gut of GPs. Different species of Streptococcus are found in the gut of the GPs, i.e., Streptococcus thermophilus [ 18 ], which are known to produce a variety of negative factors such as antibiotic-like substances, bactericidal proteins, and metabolic end-products [ 19 ].…”

“…Some lactic acid bacterial strains (LAB) play a major role in safety and quality of fermented products due to production of secondary metabolites that act as antimicrobial agents in the prevention of foodborne pathogens. Some recent have studies confirmed that probiotic organisms such as Bifidobacterium bifidum and Streptococcus thermophilus efficiently reduced the incidence of acute diarrhoea and rotavirus shedding (Vlasova et al ., ; Martinez et al ., ; Sharma et al ., ). The beneficial effect of other probiotic bacteria in the intestinal tract might be partly because of the induction of protective host antimicrobials (Maldonado Galdeano et al ., ; Power et al ., ).…”

The present research was undertaken to study the probiotic characteristics of Pichia kudriavzevii isolated from frozen idli batter. Polymerase chain reaction amplification with 18S rRNA primers confirmed Pichia kudriavzevii, a xylose-utilizing probiotic strain. It was resistant to physiological concentrations of bile salts, pepsin and pancreatic enzyme. It also showed efficient auto-aggregation as well as co-aggregation ability with four commercial probiotic yeasts and exhibited good hydrophobicity in xylene and toluene. The strain inhibited the growth of 13 enteropathogens and showed a commensal relationship with four commercial probiotic yeast and bacteria. Moreover, it was resistant to 30 antibiotics with different modes of action. The yeast exhibited thermotolerance up to 95°C for 2 h. The cell-free supernatants were also found to be heat stable, indicating the presence of thermostable secondary metabolites. Hence it could be exploited as starter culture, co-culture or probiotic in the preparation of fermented products or incorporated in heatable foods as well.

“…Furthermore, S. thermophilus along with L. delbrueckii ssp. bulgaricus can reduce cholesterol assimilation (Sharma et al, 2014). The consumption of lactic acid bacteria (LAB) has several benefits, including enhancing the immune system; improving the intestinal tract by controlling irritable bowel syndrome, inflammatory bowel disease, and suppressing endogenous and exogenous pathogens; reducing symptoms of lactose intolerance; and reducing the risk of certain cancers (Parvez et al, 2006).…”

Myrrh is an essential oil and natural flavoring approved by the US Food and Drug Administration, and it has antibacterial and antifungal activity against pathogens. Our objective was to determine the effect of an aqueous myrrh suspension on Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus counts in peptone solution and yogurt, as well as pH and titratable acidity of yogurt during 5 wk of storage at 1 to 4°C. The myrrh suspension (10% wt/vol) was prepared and incorporated into a pure culture dilution in peptone and into yogurt mix at a 1% (vol/vol) level. A control with no myrrh was also prepared, and 3 replications were conducted. Streptococcus thermophilus were enumerated using Streptococcus thermophilus agar with aerobic incubation at 37°C for 24 h, and Lactobacillus delbrueckii ssp. bulgaricus were enumerated using de Man, Rogosa, and Sharpe agar adjusted to pH 5.2, with anaerobic incubation at 43°C for 72 h. During the 8-h period after inoculation, S. thermophilus and L. delbrueckii ssp. bulgaricus counts in peptone solution at 37°C and 43°C, respectively, were not significantly different in the presence or absence of the aqueous myrrh suspension. Counts of S. thermophilus in yogurt containing myrrh (mean ± SD; 4.96 ± 0.58 log cfu/mL) were not significantly different from those in the control yogurt (4.87 ± 0.39 log cfu/mL). The log counts for L. delbrueckii ssp. bulgaricus in yogurt containing myrrh (5.04 ± 1.44 log cfu/mL) and those of the control (5.52 ± 1.81 log cfu/mL) did not differ, and the counts remained within 1 log of each other throughout 5 wk of storage. The pH of the yogurts containing the aqueous myrrh suspension was not significantly different from that of the control yogurts, and their pH values were within 0.1 pH unit of each other in any given week. Titratable acidity values remained steady around 1.1 to 1.2% lactic acid for both yogurt types throughout the storage period, with no significant differences between them. Yogurt culture bacteria can survive in the presence of a myrrh suspension in yogurt with no significant change in pH or titratable acidity. Therefore, it may be beneficial to add an aqueous myrrh suspension to yogurt.
