Project description:Seven carbon autotrophic fixation pathways were described so far. However, it is not common to find the co-existence of more than one cycle in a single cell. Here, we describe a thermophilic bacterium Carbonactinospora thermoautotrophica StC with a unique and versatile carbon metabolism. StC was isolated from a consortium found in a burning organic pile that exhibits an optimal growth temperature between 55° and 65° C. The genome analyses suggested that the strain StC potentially performs two-carbon fixation pathways, Calvin-Benson-Bassham (CBB) cycle and the Reductive citrate cycle (rTCA) and preserve a microcompartment related with CO2 concentration. To better understand the carbon fixation in StC strain, the expression of the genes of bacterial cells grown autotrophically and heterotrophically were analyzed. For our surprise the data showed the co-existing of the both carbon fixation pathways - CBB and rTCA cycles - in a cultivable thermophilic chemoautotrophic bacterium Carbonactinospora thermoautotrophica strain StC, based on integrated omics of genomics, transcriptomics, and proteomics. These two cycles working together may help microorganisms to improve the CO2 fixation. The knowledge about the co-occurrence of carbon cycle in a single cell leads open a question ‘why microorganisms use multiple pathways to fix carbon and what the advantage for this strategy?’. Advancing on this is a key to better understand the biological carbon fixation mechanism in thermophiles and prospecting the repurposing of enzymes in synthetic biology for biotechnological applications.

Project description:We sequenced and analyzed the genome of a highly inbred miniature Chinese pig strain, the Banna Minipig Inbred Line (BMI). we conducted whole genome screening using next generation sequencing (NGS) technology and performed SNP calling using Sus Scrofa genome assembly Sscrofa11.1.
Project description:Leishmania donovani WHO reference strain MHOM/IN/80/DD8 and Leptomonas seymouri isolates Ld 2001 and Ld39 were used for proteome analysis which were originally isolated from clinical cases of kala azar patients with different inherent antimonial sensitivities. Ld 2001 was Sb-S and Ld 39 was Sb-R. The genome sequencing of these isolates had confirmed co-infection with Leptomonas.
