	abstract = {<p>Palm wine, the most commonly consumed traditional alcoholic beverage in Western Africa, harbours a complex microbiota and metabolites, which plays a crucial role in the overall quality and value of the product. In the present study, a combined metagenomic and metabolomic approach was applied to describe the microbial community structure and metabolites profile of fermented saps from three palm species (Elaeis guineensis, Raphia hookeri, Borassus aethiopum) in C{\^o}te d{\textquoteright}Ivoire. Lactobacillaceae (47\%), Leuconostocaceae (16\%) and Acetobacteriaceae (28\%) were the most abundant bacteria and Saccharomyces cerevisiae (87\%) the predominant yeasts in these beverages. The microbial community structure of Raphia wine was distinctly different from the others. Multivariate analysis based on the metabolites profile clearly separated the three palm wine types. The main differentiating metabolites were putatively identified as gevotroline hydrochloride, sesartemin and methylisocitrate in Elaeis wine; derivative of homoserine, mitoxantrone in Raphia wine; pyrimidine nucleotide sugars (UDP-D-galacturonate) and myo-Inositol derivatives in Borassus wine. The enriched presence of gevotroline (an antipsychotic agent) and mitoxantrone (an anticancer drug) in palm wine supports its therapeutic potential. This work provides a valuable insight into the microbiology and biochemistry of palm wines and a rationale for selecting functional microorganisms for potential biotechnology applications.</p>

	abstract = {<p>Gut microbiota is among the factors that may be involved in healthy aging. Broader and geographically spread studies on gut microbiota of centenarians can help in identifying a common signature of longevity. We identified an endogamous Indian population with high centenarian prevalence. Here, we compared the gut microbiota composition and fecal metabolites of a centenarians group (\~{}100 years) with young people (25-45 years) of the region with the high centenarian prevalence and the nearby region of low centenarian prevalence to decipher microbial-related longevity signatures. Also, we compared our results with publicly available datasets of similar groups including 125 centenarians from three countries (Italy, Japan, China). Our comparative analysis resulted in higher biodiversity within Ruminococcaceae in centenarians, with respect to younger adults, irrespective of their nationality. We observed bacterial signatures that are common among extremely old people of different nationality. Comparative metabolites profiling identified the fecal metabolic signature of extreme aging in the Indian study population. Our analysis of the co-occurrence network and bimodal distribution of several taxa suggested the establishment of a pervasive change in the gut ecology during extreme aging. Our study might pave the way to develop gut microbiota based biomarkers for healthy aging.</p>
