Omics-guided global rewiring of yeast metabolism enables high-level production of β-lactoglobulin

ABSTRACT: This project contains untargeted metabolomic data generated to investigate the metabolic responses of Komagataella phaffii during methanol-free recombinant beta-lactoglobulin production. The study included the bovine beta-lactoglobulin-producing strain B08 and the feline beta-lactoglobulin-producing strain F01. Samples were collected under glucose and ethanol conditions at 36 h and 84 h of fermentation, with biological replicates. Untargeted metabolomic profiling was performed by LC-MS/MS in both positive and negative ion modes. The dataset was used to compare host metabolic changes associated with carbon source, fermentation stage, and beta-lactoglobulin species origin, with particular focus on central carbon metabolism, energy metabolism, amino acid metabolism, redox homeostasis, and protein synthesis and secretion. These data support multi-omics integration and metabolic engineering target selection for improving recombinant beta-lactoglobulin production in K. phaffii.

Systems-level engineering and characterization of Clostridium autoethanogenum through heterologous production of poly-3-hydroxybutyrate (PHB)

Project description:Gas fermentation is emerging as an economically attractive option for the sustainable production of fuels and chemicals from gaseous waste feedstocks. Clostridium autoethanogenum can use CO and/or CO2 + H2 as its sole carbon and energy sources. Fermentation of C. autoethanogenum is currently being deployed on a commercial scale for ethanol production. Expanding the product spectrum of acetogens will enhance the economics of gas fermentation. To achieve efficient heterologous product synthesis, limitations in redox and energy metabolism must be overcome. Here, we engineered and characterised at a systems-level, a recombinant poly-3-hydroxybutyrate (PHB)-producing strain of C. autoethanogenum. Cells were grown in CO-limited steady-state chemostats on two gas mixtures, one resembling syngas (20% H2) and the other steel mill off-gas (2% H2). Results were characterised using metabolomics and transcriptomics, and then integrated using a genome-scale metabolic model reconstruction. PHB-producing cells had an increased expression of the Rnf complex, suggesting energy limitations for heterologous production. Subsequent optimisation of the bioprocess led to a 12-fold increase in the cellular PHB content. The data suggest that the cellular redox state, rather than the acetyl-CoA pool, was limiting PHB production. Integration of the data into the genome-scale metabolic model showed that ATP availability limits PHB production. Altogether, the data presented here advances the fundamental understanding of heterologous product synthesis in gas-fermenting acetogens.

Comparative transcriptome analysis between an original and a recombinant wine yeast strain defective for KNR4/SMI1

Project description:EKD-13 is among the recently developed mannoprotein overproducing strains. It is a recombinant derivative of the well known EC1118 commercial strain, in which the ORF of all the alleles of KNR4/SMI1 was replaced by different integration cassettes. Lack of Knr4p resulted in a negligible impairment in fermentation kinetics and a net reduction in bentonite requirements to attain complete protein stabilization of white wines made out of natural grape must. In order to improve the technological characterization of this strain, and to better understand the mechanisms underlying mannoprotein oversecretion, we have analyzed kinetics of mannoprotein release and autolysis during fermentation and aging, and we have performed a genome wide expression analysis in two different steps of the fermentation process. The results give some additional clues on KNR4 function in S. cerevisiae as well as on the best application conditions for this recombinant strain.

Engineering the Secretome of Aspergillus niger for Cellooligosaccharides Production from Plant Biomass

Project description:Fermentation of sugars derived from plant biomass feedstock is crucial in achieving sustainability. Hence, utilizing customized enzymatic cocktails to obtain oligosaccharides instead of monomers is an alternative fermentation strategy to produce prebiotics, cosmetics, and biofuels. This study developed an engineered strain of Aspergillus niger producing a tailored cellulolytic cocktail capable of partially degrading sugarcane straw to yield cellooligosaccharides. The A. niger prtT strain created resulted in a reduced extracellular protease production. The prtT background was then used to create strains by deleting exoenzymes encoding genes involved in mono- or disaccharide formation. Consequently, we successfully generated a tailored prtTbglA strain by eliminating a beta-glucosidase (bglA) gene and subsequently deleted two cellobiohydrolases and one beta-xylosidase encoding genes using a multiplex strategy, resulting in the Quintuple strain (prtT; bglA; cbhA; cbhB; xlnD). When applied for sugarcane biomass degradation, the tailored secretomes produced by A. niger resulted in a higher ratio of cellobiose and cellotriose compared with glucose relative to the reference strain. Mass spectrometry revealed that the Quintuple strain secreted alternative cellobiohydrolases and beta-glucosidases to compensate for the absence of major cellulases. Enzymes targeting minor polysaccharides in plant biomass were also upregulated in this tailored strain. Tailored secretome use increased COS/glucose ratio during sugarcane biomass degradation showing that deleting some enzymatic components is an effective approach for producing customized enzymatic cocktails. Our findings highlight the plasticity of fungal genomes as enzymes that target minor components of plant cell walls, and alternative cellulases were produced by the mutant strain. Despite deletion of important secretome components, fungal growth was maintained in plant biomass.

comparative transcriptome analysis between original strain FS35 and FK520 high-yield strain OphaCfkbU

Project description:To solve the problem of low FK520 production by Streptomyces hygroscopicus var. ascomyceticus FS35, PHB synthesis gene phaC and PHB decomposition gene fkbU were co-overexpressed in parent strain FS35 to construct recombinant strain OphaCfkbU. Surprisingly, recombinant strain OphaCfkbU accumulated more biomass than parent strain FS35 in whole fermentation. Therefore, to explore the effect of co-overexpression on the strain growth, comparative transcriptome analysis were carried out between parent strain FS35 and recombinant strain OphaCfkbU. Transcriptome data showed that co-overexpression increased the utilization of sugar sources and stimulated the generation of coenzymes, ribosome, acyl carrier proteins and sulfate donors. This study revealed the internal mechanism of the effect of PHB on strain growth, proving a reference for the role of PHB in other microorganisms.

Comparative transcriptome analysis between original and evolved recombinant lactose-consuming S. cerevisiae strains

Project description:The engineering of Saccharomyces cerevisiae strains for lactose utilization has been attempted with the intent of developing high productivity processes for alcoholic fermentation of cheese whey. A recombinant S. cerevisiae flocculent strain that efficiently ferments lactose to ethanol was previously obtained by evolutionary engineering of an original recombinant that displayed poor lactose fermentation performance. In this study, we compared the transcriptomes of the original and the evolved recombinant strains (T1 and T1-E, respectively) growing in lactose, using cDNA microarrays. Microarray data revealed 173 genes whose expression levels differed more than 1.5-fold. About half of these genes were related to RNA mediated transposition. We also found genes involved in DNA repair and recombination mechanisms, response to stress, chromatin remodelling, cell cycle control, mitosis regulation, glycolysis and alcoholic fermentation. These transcriptomic data are in agreement with some of the previously identified physiological and molecular differences between the recombinants, and point to further hypotheses to explain those differences.
