Random and direct mutagenesis to enhance protein secretion in Ashbya gossypii
To improve the general secretion ability of the biotechnologically relevant fungus Ashbya gossypii, random mutagenesis with ethyl methane sulfonate (EMS) was performed. The selection and screening strategy followed revealed mutants with improved secretion of heterologous Trichoderma reesei endoglucanase I (EGI), native α-amylase and/or native β-glucosidase. One mutant, S436, presented 1.4- to 2...
متن کاملMolecular determinants of sporulation in Ashbya gossypii.
Regulation of development and entry into sporulation is critical for fungi to ensure survival of unfavorable environmental conditions. Here we present an analysis of gene sets regulating sporulation in the homothallic ascomycete Ashbya gossypii. Deletion of components of the conserved pheromone/starvation MAP kinase cascades, e.g., STE11 and STE7, results in increased sporulation. In kar3 mutan...
متن کاملThe metabolism of glucose by Ashbya gossypii.
Considerable interest has been centered on Ashbya gossypii recently because of its ability to synthesize large quantities of riboflavin. The work of Wickerham, Flickinger, and Johnson (1946) called attention to the potential industrial significance of certain strains for the manufacture of riboflavin. During the course of studies on the synthesis of riboflavin it became of importance to leam so...
متن کاملNutritional requirements and strain heterogeneity in Ashbya gossypii.
Colony radial growth rates and specific growth rates of three related Ashbya gossypii strains ATCC10895, IMI31268, MUCL29450 and an unrelated strain, CBS109.26, were measured on various carbon and nitrogen sources at pH 4.5 and pH 6.5 to elucidate physiological growth requirements and strain differences. All strains grew on yeast extract or ammonium as nitrogen sources, but not on nitrate. Subs...
متن کاملAxl2 integrates polarity establishment, maintenance, and environmental stress response in the filamentous fungus Ashbya gossypii.
In budding yeast, new sites of polarity are chosen with each cell cycle and polarization is transient. In filamentous fungi, sites of polarity persist for extended periods of growth and new polarity sites can be established while existing sites are maintained. How the polarity establishment machinery functions in these distinct growth forms found in fungi is still not well understood. We have e...
