Project description:Nannochloropsis gaditana is a microalgae of the phylum eustigmatophyceae that has been reported from fresh and brackish waters. This species has been widely cultured, mainly directed to biofuel production, due to its capacity to produce and accumulates high amounts of lipids under different culturing conditions. Furthermore, nowadays N. gaditana is being used as fish and mollusc food in aquaculture facilities. Besides, microalgae are recognized protein producers, thus, are posited as an alternative protein source that could be very valuable in areas such as agri-food or biomedicine. In this sense, seas and oceans had showed their great potential for innovation, being the main focus of the initiative Blue Growth from EU. Thereby, marine biotechnology will provide of new pharmaceuticals or industrial products from marine biomass. In order to study the whole proteome of Nannochloropsis gaditana, a proteomic approach was initiated using fresh and atomized microalgae samples, as the main commercial forms. Around 7500 peptides were detected, getting 1950 protein identification hits. Qualitative and quantitative differences were analysed. The identified proteins were categorized according to gene ontology classification. In this study, it has been developed and described the first proteomic analysis of the microalgae Nannochloropsis gaditana, containing an important number of identified proteins that may have a relevant role in different agri-food and biomedical processes.

Project description:Epigenetic modifications have not been well characterized in most microalgae species, particularly those used for biofuel production. We report the first analysis of DNA methylation of the species Picocholorum soloecismus across its growth cycle using whole-genome bisulfite sequencing. DNA methylation occurs in all three cytosine contexts (CpG, CHH, CHG) in P. soloecismus. While global DNA methylation is low overall (~1.15% of the 15 MB genome), methylation occurs appreciable quantities (12.1%) in CpG dinucleotides in a bimodal distribution. The P. soloecismus genome becomes hypomethylated during the growth cycle (across several days in culture). 5-aza-2’-deoxycytidine (5AZA) treatment was used to alter DNA methylation patterns, which resulted in altered algal physiology and site specific changes in CpG DNA methylation.

Project description:To investigate the mechanism by which the microalgae-yeast co-culture system promotes wastewater denitrification. We concluded that microalgae and yeast exhibit a mutually beneficial relationship in the co-culture system. Microalgae nitrogen metabolism can be influenced by both miRNA and mRNA, and the presence of yeast stimulates gene expression in microalgae.

Project description:We conducted a culture experiment by deeply submerging plants in swine wastewater in culturing Iris tectorum and co-culturing Iris tectorum and Dictyosphaerium sp., and found that the plants grew sub-normal in the plant-microalgae co-culture while the plants were dead after 21 days in the plant culture. We generated a comprehensive RNA-seq dataset from the submerged Iris tectorum leaves in both the plant culture and the plant-microalgae co-culture, aiming at providing information on the response mechanisms of the plants to waterlogging stress. Besides raw reads of the RNA-seq dataset, we used DEseq2 algorithms to detect the differently expressed genes in the plants between the different cultures. Additionally, we performed the plant disease resistance gene analysis for all the differentially expressed genes.

Project description:Background: Bacterial fermentation of carbohydrates from sustainable lignocellulosic biomass into biofuels by the anaerobic bacterium Clostridium acetobutylicum is a promising alternative energy source to fossil fuels. Understanding the complex metabolic pathways it employs and how they are regulated will contribute to improved biofuel production. Recently, it has been demonstrated that xylose is not appreciably fermented in the presence of arabinose, suggesting a hierarchy of pentose utilization in this organism. Our goal is to uncover if transcriptional regulation contributes to this hierarchy. Results: Growth and sugar consumption rates showed that arabinose, like glucose, actively represses xylose utilization in cultures fermenting xylose. RNA-Seq revealed there was a large overlap in differentially regulated genes after addition of arabinose or glucose, suggesting a common mechanism of regulation. A putative ORF was identified that may be important for transcriptional regulation in response to the nutritional state of the cells. Conclusions: Decreased xylose consumption, increased acetate production, and transcription of the phosphoketolase gene (CA_C1343) revealed a transition of pentose catabolism from the pentose phosphate pathway to the phosphoketolase pathway after addition of arabinose. Together, these results substantiate the claim that arabinose is utilized preferentially over xylose in C. acetobutylicum. Furthermore, they demonstrate that this phenomenon is modulated in part at the transcriptional level, and they provide valuable insight into potential mechanisms for altering pentose utilization to modulate fermentation products for biofuel production.
