macrophages (Pathmakanthan et al. 2004). They can also act on immunological as
well as nonimmunological defense mechanism of the gut (Majamaa and Isolauri
1997). Bifidobacteria and lactobacilli can also initiate IgA response against harmful
antigens and reduce the production of cytokines responsible for strong IgG and IgE
responses and allergies.
Low dietary fiber can cause colon cancer and probiotics can reduce the risk.
Results from animal and in vitro studies showed reduction in DNA changes and
tumor formation. Probiotics can change enzyme activities in the gut and modify
regulation of apoptosis. Metabolites produced by certain lactobacilli are reported to
have a positive effect on adults with mild hypertension (Liong 2007). Proteolytic
cleavage of casein by L. helveticus leads to formation of metabolites that can reduce
blood pressure. Decline in lipid level and resistance to insulin resistance by probiotic organisms was also reported by Zohreh et al. (2013).
Lactobacilli can bind mutagenic heterocyclic amines, and tumor formation could
be delayed by the reduced absorption of mutagenic compounds, as reported by
Hayatsu and Hayatsu (1993). Thus, probiotic food intake can reduce cancer risk as
per Praveen et al. (2010). E. coli and Clostridium perfringens produce nitro reductase and beta-glucuronidase enzymes and, by maintaining favorable pH and other
conditions, phagocytes tend to destroy tumor cells (Wollowski et al. 2001).
Bifidobacteria inhibit Clostridium perfringens and pathogens such as Salmonella
and Shigella, which can cause colon and rectal cancer. They also improve lipid
metabolism, reduce nitrogen excretion, and enhance the absorption of essential
minerals. Insufficient or preliminary evidence exists for probiotics against prevention of cancer, reduction in cholesterol, enhancement of oral microbiota, and therapy for ischemic heart-associated and autoimmune disorders as per de Vresse and
Schrezenmeir (2008).
New approaches for managing the biofilm formation of infectious bacteria were
well studied, and probiotics were proposed to manage antibiotic resistance and difficulty in controlling biofilm formation to eradicate infections. Probiotics were
effective against disruption of biofilms or restoration of beneficial biofilms.
Intravaginal applications of lactobacilli have been reported as effective against
bacterial vaginosis because they maintain a favorable vaginal pH in the acidic range
and cause production of antimicrobial metabolites (Anukam et al. 2006; Falagas
et al. 2007). Bacterial vaginosis is caused by displacement of lactobacilli to anaerobic pathogens. In human studies, Gardnerella species were displaced (Burton et al.
2003) and Lactobacillus strains can prevent Candida albicans biofilms and also can
eliminate yeast in vitro (Kohler and Reid 2006).
When used in skin care, probiotics help to prevent accelerated skin aging at a
deeper level to boost cellular function, reduce inflammation, and promote luminosity, firmness, and hydration (Huang and Tang 2015). Orally ingested probiotics
affected the skin by mechanisms initiated in the gut by changing systemic immune
responses such as stimulating receptors and modulating specific T cells (Krutmann
2012). Probiotics are reported to replenish resident microbes that were drastically
reduced in the presence of dysbiosis-associated skin inflammation (Gao et al. 2008).
Effects of probiotic microbes in the cosmetic industry are not well studied even
