Mapping the functional and strain diversity of the main microbiota involved in cocoa fermentation from Cote d'Ivoire.

The variable quality of cocoa produced by farmers is still a problem in the value chain, strongly depending on microbial activities. We analyzed the variability of cocoa microbiota from all twelve producing regions in Cote d'Ivoire, and described the geographical distribution of isolated microbiota, using a mapping. Microbial species were identified by ribosomal genes sequencing, strains were typed by RFLP and their techno-functional capacities were further investigated.

Acetic acid bacteria (AAB) involved in cocoa fermentation from Ivory Coast: species diversity and performance in acetic acid production.

In this study, we investigated the diversity of AAB from fermenting cocoa and the production of acetic acid in response to various environmental conditions. Ribosomal 16S gene sequence analysis and PCR-RFLP showed a restricted microbiota mainly composed of , and sp., consistently found in all six regions studied.

Antimicrobial resistance and virulence associated genes in Campylobacter jejuni isolated from chicken in Côte d'Ivoire.

Introduction: Campylobacter jejuni is one of the major causes of gastroenteritis worldwide of the last century. The aim of this study was to investigate the antibiotics profiles and the virulence gene in C. jejuni strains isolated from chicken in Côte d'Ivoire.

Lactic acid bacteria involved in cocoa beans fermentation from Ivory Coast: Species diversity and citrate lyase production.

Microbial fermentation is an indispensable process for high quality chocolate from cocoa bean raw material. lactic acid bacteria (LAB) are among the major microorganisms responsible for cocoa fermentation but their exact role remains to be elucidated. In this study, we analyzed the diversity of LAB in six cocoa producing regions of Ivory Coast.

Pichia kudrazevii and Candida nitrativorans are the most well-adapted and relevant yeast species fermenting cocoa in Agneby-Tiassa, a local Ivorian cocoa producing region.

Cocoa bean fermentation is a spontaneous and still poorly controlled process that very often leads to end-products of heterogeneous quality. This fermentation is driven by a succession of complex microbial communities where yeasts play key roles during the first stages of the process. In this study, we identified and analyzed the growth dynamics of yeasts involved in cocoa bean fermentation from the Ivorian region called Agneby-Tiassa.
