Project description:To study mixotrophy, it is desirable to have an organism capable of growth in the presence and absence of both organic and inorganic carbon sources, as well as organic and inorganic energy sources. Metallosphaera sedula is an extremely thermoacidophilic archaeon which has been shown to grow in the presence of inorganic carbon and energy source supplements (autotrophy), organic carbon and energy source supplements (heterotrophy), and in the presence of organic carbon and inorganic energy source supplements. The recent elucidation of M. sedula’s inorganic carbon fixation cycle and its genome sequence further facilitate its use in mixotrophic studies. In this study, we grow M. sedula heterotrophically in the presence of organic carbon and energy sources (0.1% tryptone), autotrophically in the presence of inorganic carbon and energy sources (H2 + CO2), and “mixotrophically” in the presence of both organic and inorganic carbon and energy sources (0.1% tryptone + H2 + CO2 ) to characterize the nature of mixotrophy exhibited.

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT), and Podot1 knockout strain (ΔPodot1) in different carbon sources. The deletion of Podot1 downregulated genes involved in the septin complex, extracellular region, and interspecies interaction between organisms when strains were cultivated with 2% glucose as carbon sources, and downregulated genes involved in cellulase activity, cellulose binding, glucosidase activity, and polysaccharide catabolic process when strains were cultivated with 1% microcrystalline cellulose and 1% wheat bran as carbon sources. We find the extracellular region was downregulated under both different carbon sources in ΔPodot1. This study provides the information that PoDot1 function are required in mycelial development and hydrolase activity of P. oxalicum.

Project description:The goals of this study are to compare different gene expressions for Penicillium oxalicum wild type strain (WT), and set2 knockout strain (Δset2) in different carbon sources. The deletion of set2 upregulated genes involved in oxidation- reduction process, extracellular region, and plasma membrane ATP synthesis coupled proton transport both with 2% glucose or 1% cellulose and 1% wheat bran as carbon sources. We find the expression levels of 20 secondary metabolism gene clusters were upregulated or downregulated under different carbon sources in Δset2. This study provides the information that SET2 function are required in conidiation and hydrolase activity of P. oxalicum.

Project description:Goal of this study was to investigate the metabolic adaptation of C. auris to different carbon sources (malic acid, α-ketoglutarate, proline) and nitrogen sources (dipeptides). As a control medium with glucose as carbon source and ammonium sulfate as nitrogen source was used. Transcriptional profiles were compared after 4 h incubation at 37°C.

Project description:Bacteria have evolved different mechanisms to catabolize carbon sources from a mixture of nutrients. They first consume their preferred carbon source, before others are used. Regulatory mechanisms adapt the metabolism accordingly to maximize growth and to outcompete other organisms. The human pathogen Campylobacter jejuni is an asaccharolytic Gram-negative bacterium that catabolizes amino acids and organic acids for growth. It prefers serine and aspartate as carbon sources, however it lacks all regulators known to be involved in regulating carbon source utilization in other organisms. In which manner C. jejuni adapts its metabolism towards the presence or absence of preferred carbon sources is unknown. In this study, we show with transcriptomic analysis and enzyme assays how C. jejuni adapts its metabolism in response to its preferred carbon source serine. In the presence of serine as well as lactate and pyruvate C. jejuni represses the utilization of other carbon sources, by repressing the expression of a number of central metabolic enzymes. The regulatory proteins RacR, Cj1000 and CsrA play a role in the regulation of these metabolic enzymes. This metabolism dependent transcriptional repression correlates with an accumulation of intracellular succinate. Hence, we propose a demand-based catabolite repression mechanism in C. jejuni, which depends on the intracellular succinate level.
