Cocultures of anaerobic fungi and chain-elongating bacteria stably convert lignocellulose to butyrate and hexanoate

ABSTRACT: This study looks at the gene expression of two chain-elongating bacteria, Pseudoramibacter alactolyticus and Megasphaera elsdenii, in monoculture and in coculture with anaerobic gut fungi (Neocallimastix lanati). P. alactolyticus in particular has appeared stable in synthetic cocultures with anaerobic fungi based on metabolic output, and this RNA-seq study was designed to further assess that stability. Additionally, chain-elongating bacteria can use fungal fermentation products to generate short- and medium-chain fatty acids, and this study was employed to see how genes involved in this process (reverse beta oxidation) were regulated in coculture compared to monoculture.

Transcriptome analyses of Filifactor alocis ATCC35896 and Porphyromonas gingivalis W83 in mono-culture as compared to co-culture under hydrogen peroxide stress conditions

Project description:Oal anaerobic bacteria have to face constant oxidative stress in order to survive in the inflammatory environment of the periodontal pocket. In this study, we analyzed the transcriptome profiles of P. gingivalis and Filifactor in monoculture as compared to P. gingivalis+F.alocis coculture under H2O2 stress condtions, to analyze the genes responsible for enhanced survival of P. gingivalis in presence of F. alocis under oxidative-stress conditions.

Stem cell coculture

Project description:This study aims to to compare the gene transcription profiles of endothelial cells and stem cells, when they are cultured alone or when they are cultured together. Thus there are two major questions - how do the cells differ, and how do the cells influence each other's gene expression. Thus there are 4 types of sample: endothelial cell monoculture, endothelial cell coculture, stem cells monoculture, stem cell coculture. There are also 4 biological replicates (independent experiments) leading to 16 array data files.
