Traditional and Artisanal Beverages in Nigeria: Microbial Diversity and Safety Issues

A review of up to 90 articles on the microorganisms associated with important artisanal or traditional beverages in Nigeria was carried out. This resulted in an overview of the prevalent microorganisms associated with soymilk, nono (fermented cow milk), tiger nut milk, yoghurt, kunu, zobo, palm wine and the local beers pito and brukutu. The bacteria genera, namely Bacillus, Escherichia, Lactobacillus, Staphylococcus, and Streptococcus, were detected in all nine beverages. On the contrary, this survey resulted in finding that the genera Saccharomyces, Aspergillus, Candida, and Penicillium were the eukaryotic microorganisms isolated in all beverages. The occurrence of fungal isolates, which can be responsible for producing mycotoxins, is a concern and shows the need for post-production tests. Overall, there is a low prevalence of bacteria associated with hygiene, especially the Escherichia genus in alcoholic beverages such as palm wine, pito and burukutu, which may be due both to a low acidity and high ethanol content. However, the prevalence of hygiene indicator genera was higher in nonalcoholic drinks, probably because of incorrect practices during processing. The magnitude of the production and sales of unregulated local beverages in Nigeria has reached the stage where significant regulation and food safety standards are required to safeguard public health. An opportunity exists to monitor and characterize the microbial flora of the artisanal beverages using molecular methods at all stages of production and storage.

Kweichow Moutai ameliorates alcohol-induced liver fibrosis in mice by targeting the NFκB pathway

Previous epidemiological and histopathological studies have demonstrated that long-term computation of Kweichow Moutai liquor (Moutai) could induce fatty liver disease but few of these patients with fatty liver will develop hepatic fibrosis or cirrhosis. Moutai liquor has a different brewing technique from other white wine, which may generate various microorganisms in the unique geographical conditions and may produce plenty of vitamins, amino acids, and several essential microelements. In the current study, we evaluated the potential protective effect of Moutai liquor in alcohol-induced liver fibrosis mouse model. Both in vivo and in vitro studies were performed for exploring the possible mechanisms in suppressing liver fibrosis by Moutai. We demonstrated that Moutai treatment induced hepatic stellate cell (HSC) apoptosis and suppressed collagen deposition, as well as attenuated hepatic fibrosis. The antifibrosis mechanism of Moutai was possibly related with the inhibition of Kupffer cell and HSC activation via suppressing NFκB nuclear translocation and preventing the expression of pro-inflammatory cytokines. It is worth noting that although Moutai attenuates liver fibrosis, it still causes lipid metabolic abnormalities in mouse liver and induces fatty liver. Kweichow Moutai may ameliorate alcohol-induced liver fibrosis in mice by targeting the NFκB pathway.
