Project description:Streptomyces sp. M7 has demonstrated ability to remove lindane from culture media and soils. In this study, we used MS-based label-free quantitative proteomic to understand lindane degradation and its metabolic context in Streptomyces sp. M7. We identified the proteins involved in the up-stream degradation pathway. Our results demonstrated that mineralization of lindane is feasible since proteins from an unusual down-stream degradation pathway were also identified. Degradative steps were supported by an active catabolism that supplied energy and reducing equivalents in the form of NADPH. This is the first study in which degradation steps of an organochlorine compound and metabolic context are elucidate in a biotechnological genus as Streptomyces. These results serve as basement to study other degradative actinobacteria and to improve the degradation processes of Streptomyces sp. M7.

Project description:Activating the cryptic secondary metabolic gene clusters is a vital research field in Streptomyces. The marine Streptomyces sp. FJNU027 strain which could produce tirandamycins was cultured in the oligotrophic medium. Compared with normal medium, a differential product in oligotrophic culture was found by HPLC assay. After mass fermentation, 2 mg of the differential product was obtained from 30 L fermentation broth by solvent extraction, column chromatography over sephadex LH-20 and reverse phase C18, and other methods. It was identified as 4,4',5,5'-tetramethyl-[1,1'- diphenyl]-2,2'-diol by NMR and MS data. The production of this compound was enhanced with the increment of cultural time. Transcriptome sequencing analysis showed that the highest upregulated genes under oligotrophic condition were glycosidase, TraR/DksA C4-type zinc finger protein and ribonuclease encoding genes, while the expression of a MarR family transcriptional regulator was most significantly decreased under oligotrophic condition. The results indicate that oligotrophic culture is an effective method for altering the secondary metabolism of Streptomyces.

Project description:This study aimed to investigate the variations in the protein composition of Streptomyces sp. PU10 when cultivated with either Impranil (polyestere-polyurethane) or glucose as the carbon source. We analyzed both the intracellular and extracellular protein fractions to gain insights into the intricate processes involving PU degradation, intermediate metabolic pathways in PU degradation, and the connection between primary and secondary metabolism within Streptomyces sp. PU10.

Project description:Background: Frankia sp. strains are actinobacteria that form N2-fixing root nodules on angiosperms. Several reference genome sequences are available enabling transcriptome studies in Frankia sp. Genomes from Frankia sp. strains differ markedly in size, a consequence proposed to be associated with a high number of indigenous transposases, more than 200 of which are found in Frankia sp. strain CcI3 used in this study. Because Frankia exhibits a high degree of cell heterogeneity as a consequence of its mycelial growth pattern, its transcriptome is likely to be quite sensitive to culture age. This study focuses on the behavior of the Frankia sp. strain CcI3 transcriptome as a function of nitrogen source and culture age. Results: To study global transcription in Frankia sp. CcI3 grown under different conditions, complete transcriptomes were determined using high throughput RNA deep sequencing. Samples varied by time (five days vs. three days) and by culture conditions (NH4+ added vs. N2 fixing). Assembly of millions of reads revealed more diversity of gene expression between five-day and three-day old cultures than between three day old cultures differing in nitrogen sources. Heat map analysis organized genes into groups that were expressed or repressed under the various conditions compared to median expression values. Twenty-one SNPs common to all three transcriptome samples were detected indicating culture heterogeneity in this slow-growing organism. Significantly higher expression of transposase ORFs was found in the five-day and N2-fixing cultures, suggesting that N starvation and culture aging provide conditions for on-going genome modification. Transposases have previously been proposed to participate in the creating the large number of gene duplication or deletion in host strains. Subsequent RT-qPCR experiments confirmed predicted elevated transposase expression levels indicated by the mRNA-seq data. Conclusions: The overall pattern of gene expression in aging cultures of CcI3 suggests significant cell heterogeneity even during normal growth on ammonia. The detection of abundant transcription of nif (nitrogen fixation) genes likely reflects the presence of anaerobic, N-depleted microsites in the growing mycelium of the culture, and the presence of significantly elevated transposase transcription during starvation indicates the continuing evolution of the Frankia sp. strain CcI3 genome, even in culture, especially under stressed conditions. These studies also sound a cautionary note when comparing the transcriptomes of Frankia grown in root nodules, where cell heterogeneity would be expected to be quite high.
