Project description:Polyhydroxyalkanoates (PHAs) are bio-based, biodegradable polyesters that can be produced from organic-rich waste streams using mixed microbial cultures. To maximize PHA production, mixed microbial cultures may be enriched for PHA-producing bacteria with a high storage capacity through the imposition of cyclic, aerobic feast-famine conditions in a sequencing batch reactor (SBR). Though enrichment SBRs have been extensively investigated a bulk solutions-level, little evidence at the proteome level is available to describe the observed SBR behavior to guide future SBR optimization strategies. As such, the purpose of this investigation was to characterize proteome dynamics of a mixed microbial culture in an SBR operated under aerobic feast-famine conditions using fermented dairy manure as the feedstock for PHA production. At the beginning of the SBR cycle, excess PHA precursors were provided to the mixed microbial culture (i.e., feast), after which followed a long duration devoid of exogenous substrate (i.e., famine). Two-dimensional electrophoresis was used to separate protein mixtures during a complete SBR cycle, and proteins of interest were identified.

Project description:It is a cost-effective production method to synthesize polyhydroxyalkanoate (PHA) through mixed bacterial consortium fermentation. Pseudomonas balearica R90 and Brevundimonas diminuta R79, which represent the species of abundance increase in the propylene oxide activated sludge, were selected as the model to study the interaction mechanism of PHA synthesis by co-culture between strains. RNA-Seq analysis showed that the expression of acs and phaA genes of R79 and R90 increased in the mixed culture group, which enhanced their ability of acetic acid utilization and poly-β-hydroxybutyrate (PHB) synthesis. So the dry cell weight and the yield of PHB in the mixed culture group was prominently higher than that in the pure culture group. In addition, two-component system genes, quorum- sensing genes, flagellar synthesis related genes and chemotaxis related genes in R90 were enriched at 4 days, so R90 could adapt to the domestication environment more quickly, making the proportion of R90 higher than that of R79 at 4 days. However, the acs gene expression of R79 was higher than that of R90. Therefore, R79 can make better utilize acetate in the domestication solution environment, thus occupying the final dominant position.

For full list of modENCODE projects, see http://www.genome.gov/26524648 Project Goal: We are identifying the DNA binding sites for 300 transcription factors in C. elegans. Each transcription factor gene is tagged with the same GFP fusion protein, permitting validation of the gene's correct spatio-temporal expression pattern in transgenic animals. Chromatin immunoprecipitation on each strain is peformed using an anti-GFP antibody, and any bound DNA is deep-sequenced using Solexa GA2 technology.
