Transcriptome analysis of the Novosphingobium resinovorum SA1 strain grown on sulfanilic acid and glucose

ABSTRACT: Novosphingobium resinovorum strain SA1 is one of few strains capable of degrading sulfanilic acid which is a widely used representative of sulfonated aromatic compounds. In order to identify the elements involved in the biodegradation process and to understand the metabolic responces of the cells exposed to this aromatic compound, we performed a whole transcriptome analysis of cells grown on sulfanilic acid and glucose. Additionally, for distinguish the potential stress/starvation effects of the xenobiotic we compared the transcript profiles of samples taken from both the exponential and stationary growth phases.

Aromatic dimer dehydrogenases from Novosphingobium aromaticivorans reduce aromatic diketones

Project description:Aromatic diketones are a major product of formic acid lignin depolymerization. Novosphingobium aromaticivorans can degrade these diketones, but the enzymes used in this process were unknown. We used RNA-Seq to identify aromatic dimer dehydrogenases as potential candidates for the initial reduction of the aromatic G-diketone, then verified this using in vitro enzyme assays.

Catabolism of b-5 linked aromatics by Novosphingobium aromaticivorans

Project description:Aromatic compounds are an important renewable source of commodity chemicals traditionally produced from fossil fuels. Aromatics derived from plant lignin can potentially be converted into commodity chemicals through depolymerization followed by microbial funneling of monomers and low molecular weight oligomers. This study investigates the catabolism of the b-5 linked aromatic dimer dehydrodiconiferyl alcohol (DC-A) by the bacterium Novosphingobium aromaticivorans. We used genome wide screens to identify candidate genes involved in DC-A catabolism. Subsequent in vivo and in vitro analyses of these candidates elucidated a catabolic pathway composed of four required gene products and several partially redundant dehydrogenases that convert DC-A to aromatic monomers that can be funneled into the central aromatic metabolic pathway of N. aromaticivorans. Specifically, a newly identified γ-formaldehyde lyase, PcfL, opens the phenylcoumaran ring to form a stilbene and formaldehyde. A lignostilbene dioxygenase, LsdD, then cleaves the stilbene to generate the aromatic monomers, vanillin and 5-formylferulate (5-FF). We also show that an aldehyde dehydrogenase FerD oxidizes 5-FF before it is decarboxylated by LigW, yielding ferulic acid. We found that some enzymes involved in b-5 catabolism pathway can act on multiple substrates and that some steps in the pathway can be mediated by multiple enzymes, providing new insights into the robust flexibility of aromatic catabolism in N. aromaticivorans. We performed a comparative genomic analysis to predict that key enzymes in the newly discovered b-5 aromatic catabolic pathway are common among Sphingomonads.

Transcriptome analysis of Novosphingobium sp. THN1 during microcystin-LR degradation under different carbon concentrations

Project description:The bacterium Novosphingobium sp. THN1 (THN1) is capable of degrading microcystin-LR (MCLR). To get an insight into genes expression during MCLR degradation and the regulation of different carbon concentrations on MCLR degradation, we performed RNA-seq of THN1 during MCLR degradation under different carbon concentrations.

Metabolic capacities of Novosphingobium sp. HR1a in the rhizosphere

Project description:Rhizoremediation, the biotechnology of the utilization of rhizospheric microorganisms associated with plant roots for the elimination of soil contaminants, is based on the ability of microorganisms to metabolize nutrients from plant root exudates, in order to survive the stressful conditions of the rhizosphere, and thereby, to co-metabolize or even mineralize toxic environmental contaminants. Novosphingobium sp. HR1a is a bacterial strain able to degrade a wide variety of polycyclic aromatic hydrocarbons (PAHs). We have demonstrated that this bacterium is able to grow in vegetated microcosms and to eliminate phenanthrene in the presence of clover faster than in non-vegetated systems, establishing a positive interaction with clover. We have studied the molecular basis of this interaction by phenomic, metabolomic and transcriptomic analyses, demonstrating that the positive interaction between clover and Novosphingobium sp. HR1a is a result of the bacterial utilization of different carbon and nitrogen sources (such as sugars, amino acids and organic acids) released during seedling development, and the capacity of exudates to induce the PAH degradation pathway. These results are pointing out to Novosphingobium sp. HR1a as a promising strain for the bioremediation of PAH-contaminated soils.

A unique role of Cohesin-SA1 in gene regulation and development [Expression]

Project description:Vertebrates have two cohesin complexes that consist of Smc1, Smc3, Rad21/Scc1 and either SA1 or SA2, but their functional specificity is unclear. Mouse embryos lacking SA1 show developmental delay and die before birth. Comparison of the genome wide distribution of cohesin in wild-type and SA1-null cells reveals that SA1 is largely responsible for cohesin accumulation at promoters and at sites bound by the insulator protein CTCF. As a consequence, ablation of SA1 alters transcription of genes involved in biological processes related to Cornelia de Lange syndrome (CdLS), a genetic disorder linked to dysfunction of cohesin. We show that the presence of cohesin-SA1 at the promoter of myc and of protocadherin genes positively regulates their expression, a task that cannot be assumed by cohesin-SA2. Cohesin binding pattern along some gene clusters is also affected by the lack of SA1, leading to dysregulation of the genes within. We hypothesize that impaired cohesin-SA1 function in gene expression underlies the molecular etiology of CdLS. Two-condition experiment, SA1 KO vs. WT cells. 3 Biological replicates.
