Sheppard2018 - Toxic Activity of K28 Killer Yeast Protein

ABSTRACT: A deterministic model built in COPASI simulating the toxic activity of the K28 toxin produced by Saccharomyces cerevisiae. It simulates the kinetics of inoculating a susceptible population of cells with the toxin and can be used to display the toxin acting via its primary mechanistic pathway at high concentrations or the secondary action pathway, via induced apoptosis, seen at low concentrations.

Dynamic modelling of the killing mechanism of action by virus-infected yeasts.

Killer yeasts are microorganisms, which can produce and secrete proteinaceous toxins, a characteristic gained via infection by a virus. These toxins are able to kill sensitive cells of the same or a related species. From a biotechnological perspective, killer yeasts are beneficial due to their antifungal/antimicrobial activity, but also regarded as problematic for large-scale fermentation processes, whereby those yeasts would kill starter cultures species and lead to stuck fermentations.

Project description:Resistance of Saccharomyces cerevisiae to high furfural concentration is based on NADPH-dependent reduction by at least two oxireductases. Biofuels derived from lignocellulosic biomass hold promises for a sustainable fuel economy, but several problems hamper their economical feasibility. One important problem is the presence of toxic compounds in processed lignocellulosic hydrolysates with furfural as a key toxin. While Saccharomyces cerevisiae has some intrinsic ability to reduce furfural to the less toxic furfuryl alcohol, higher resistance is necessary for process conditions. By comparing an evolved, furfural resistant strain and its parent in micro-aerobic, glucose-limited chemostats at increasing furfural challenge, we elucidate key mechanism and the molecular basis of both natural and high-level furfural resistance. At lower furfural concentrations, NADH-dependent oxireductases are the main defence mechanism. At concentrations above 15 mM, however, [1-13C]-flux and global array-based transcript analysis demonstrated that the NADPH-generating flux through pentose-phosphate pathway increases and that NADPH-dependent oxireductases became the major resistance mechanism. The transcript analysis further revealed that iron transmembrane transport is up-regulated in response to furfural. While these responses occur in both strains, high-level resistance in the evolved strain was based on strong induction of ADH7, the uncharacterised ORF YKL071W and 4 further, likely NADPH-dependent oxireductases. By overexpressing the ADH7 gene and the ORF YKL071W, we inverse engineered significantly increased furfural resistance in the parent strain, thereby demonstrating these two enzymes to be key elements of the resistance phenotype. Experiment Overall Design: RNA levels were measured in glucose limited, micro-aerobic chemostat cultures with different concentrations of the growth inhibitor furfural. Two strains were compared: TMB3400-FT30-3 is a strain that has been evolutionary adapted to withstand high furfural concentrations. TMB3400 is its less resistant parent. Number of biological replicates: 2-3.
