Project description:Welan gum is mainly produced by Sphingomonas sp. ATCC 31555 and has broad applications in industry such as that in cement production. Both carbon and nitrogen sources are essential for welan production. However, how nitrogen sources affect the metabolism and gene transcription of welan remains elusive. Here, we used next-generation sequencing RNA-seq to analyze the transcriptome of Sphingomonas sp. ATCC 31555 in the presence of inorganic or organic nitrogen sources. Enriched gene expression and pathway analysis suggest that organic nitrogen sources significantly enhanced the expression of genes in central metabolic pathways of Sphingomonas sp. ATCC 31555 and those critical for welan synthesis compared to that observed using inorganic nitrogen sources. The present study improves our understanding of the molecular mechanism underlying the use of nitrogen in welan synthesis in Sphingomonas sp., as well as provides an important transcriptome resource for Sphingomonas sp. in relation to nitrogen sources.

Project description:Thiabendazole (TBZ), a benzimidazole used against postharvest fungal growth and as anthelmintic in livestock farming, is highly persistent in soil (DT50> 1-2 years) and therefore challenging concerning its environmental management. In our recent copious attempts to isolate organisms that degrade TBZ, at best, we ended up with a soil microbial enrichment capable of accelerated TBZ degradation. Here, we employed a multi-omic approach combined with DNA stable isotope probing (SIP) for elucidating the underlying system complexity. We obtained 18 high-quality metagenome-assembled genomes, with six being dominant and versatile concerning their putative xenobiotics degradation ability. SIP combined with microbiome analysis verified our previous results about the key role of a Sphingomonas strain in TBZ degradation. Next to this, metabolomics suggested minimal/no cross-feeding events, and Sphingomonas being the sole TBZ degrader. RNA sequencing and proteomics analysis of the consortium using TBZ or succinate as sole carbon sources showed the enhanced expression in Sphingomonas of a carbazole dioxygenase locus with putative role in the TBZ degradation. Gene expression networking analysis suggested the interaction of Sphingomonas with a Hydrogenophaga strain that possibly contributes to the overall cobalamin balance. Our study depicts the need for integrated omic approaches for understanding complex interactions frequently occurring in bioremediation.

Sphingomonas sp. ATCC 31555 strain (stored in our laboratory) was first seeded in an inoculum medium (20 g/L glucose, 3 g/L yeast extract, 3 g/L malt extract, and 5 g/L fish meal protein peptone, pH 7.0), and then cultured in a fermentation medium containing 40 g/L sucrose, 4.0 g/L nitrogen source, 0.6 g/L KH2PO4, and 0.2 g/L MgSO4.7H2O at 37°C. The nitrogen sources used in the present study were as follows: NaNO3 (4.0 g/L) as inorganic nitrogen (IN), beef extract (4.0 g/L) as organic nitrogen (ON), and NaNO3 (1.5 g/L) + beef extract (2.5 g/L) as complex nitrogen (CN). All cultivations were conducted in flasks with constant rotary shaking at 400â??1,000 rpm and 37°C.
