Tetrasphaera elongata prospers in dynamic oxic/anoxic systems by metabolic pre-adaptation and dismissal of the hierarchical control of anaerobic gene expression

ABSTRACT: The physiological adaptations of the WWTP isolate T. elongata str. LP2 during an oxic/anoxic shift experiment were analyzed by HRMS-proteomics. E. coli was used as reference organism as it shares several metabolic capabilities and is regularly introduced to wastewater treatment plants, but without succeeding there. In contrast to E. coli, T. elongata was able to steadily grow and did not need to activate additional metabolic pathways for anaerobic energy harvest. At the same time, given substrates were exploited far more efficient than by E. coli. Based on the acquired data, we hypothesize that T. elongata shows high metabolic robustness when encountering the WWTP which enables continuous growth to successfully compete in this environment.

Frequency of change determines effectiveness of microbial response strategies in sulfidic stream microbiomes

Project description:Chemostat incubations were established and inoculated with sediments collected from Canyon Creek, Calgary, Alberta, Canada. The chemostats experienced oxic-anoxic change of different frequency, High-frequency, Medium-frequency and Low-frequency. 18 samples were collected at the end of the final oxic phase and the final anoxic phase in the triplicated chemostats for metagenomic and metaproteomic analysis. 26 genomes were assembled from metagenomes. Proteomes were used to investigate translational regulation of each population associated with a genome.

FNR- vs WT in anoxic conditions

Project description:Salmonella enterica var. Typhimurium (S. Typhimurium) is a Gram-negative, facultative intracellular pathogen that infects the intestinal tracts of humans and animals. In the host, S. Typhimurium encounters a wide range of oxygen concentrations going from oxic conditions in the stomach to near anoxic conditions in the distal sigmoid colon-rectal junction. In Escherichia coli, FNR (Fumarate Nitrate Reductase) is one of the main regulatory proteins involved in oxygen sensing and in controlling the transcription of the genes required for the aerobic/anaerobic transition.. However, the role of FNR in S. Typhimurium is largely unknown. To assess its role in S. Typhimurium, we constructed an FNR- mutant (NC983) in the pathogenic wild-type (WT) strain, ATCC14028s. The WT and the fnr- mutant strains were grown under anaerobic conditions in a Coy Anaerobic Chamber. Total RNAs were isolated when the cultures reached an OD600 of 0.3 (mid-log). Microarray slides were used to compare the global expression patterns of the two strains (i.e., 14028s vs. NC983). On each slides there were three replicas of the Salmonella genome and we swapped dyes, thus having a total of six replicates for each gene.

RNA expression data from Halobacterium NRC-1 in response to oxic/anoxic transitions, verification experiment

Project description:In order to ensure the reproducibility of the transcriptional response of Halobacterium NRC-1 to oxic/anoxic transitions, we repeated global mRNA measurements for the oxygen time series data in GSE5924, except that cultures were equilibrated to high oxygen for 12 hours prior to the start of the experiment rather than low oxygen. The results of these data suggest that there is good (~60%) reproducibility between datasets, and that Halobacterium responds robustly to oxic/anoxic transitions. Keywords: time series

RNA-seq of Escherichia coli under fluctuating ammonia availability (limitation-depletion)

Project description:In large-scale production processes, metabolic control is typically achieved by limited supply of essential nutrients like glucose or ammonia. With increasing bioreactor dimensions, microbial producers such as Escherichia coli are exposed to changing substrate availabilities due to limited mixing. In turn, cells sense and respond to these dynamic conditions leading to frequent activation of their regulatory programs. Previously, we characterized short- and long-term strategies of cells to adapt to glucose fluctuations. Here, we focused on fluctuating ammonia supply, while studying a continuously running two-compartment bioreactor system comprising a stirred tank reactor (STR) and a plug flow reactor (PFR). Genes were repeatedly switched on/off when E. coli returned to the STR. Moreover, E. coli revealed highly diverging long-term transcriptional responses in ammonia compared to glucose fluctuations. The identification of target genes may help to create robust cells and processes for large-scale application.

Metabolic modeling of antibiotic and cytotoxic effects of the isoquinoline IQ-238 in S. aureus, S. epidermidis and human cells

Project description:Isoquinolines (IQs) are natural substances with antibiotic potential. IQ-238 is a synthetic analog of the novel-type N,C-coupled naphtylisoquinoline (NIQ) alkaloid ancisheynine. Gene expression data, cytotoxicity measurements and metabolic modelling is combined to assess the effects of the N,C-coupled naphtylisoquinoline (NIQ) compound IQ-238 on Staphylococcus aureus and man as a potential lead for novel antibiotics. It possesses a high activity against staphylococci but has low cytotoxicity in human cell lines. Genome annotation identified missed enzymes (validated by PCR) in the primary (e.g. nucleotide) metabolism of staphylococci. Gene expression changed after cultivation with IQ-238. Metabolic modelling did yield the adaptations of all central enzymes, including those not affected by significant gene expression changes. The data show that IQ-238 interferes with the carbohydrate metabolism in staphylococci. The data suggest that IQ-238 is a promising lead for antibiotic therapy against S. aureus infections.
