Roussos Biología aeration Germination temperature initial moisture Aspergillus niger Environmental factors infl uencing spore germination of three fi lamentous fungi( Aspergillus niger Aspergillus niger , Myceliophthora thermophila, Rhizopus microsporus) were studied.Four substrates, all containing sugar cane bagasse as support, were tested for sporegermination. Different temperature, moisture, aeration and humidity conditions wereevaluated for each species. Spore germination was assessed by observing emergenceof the germ tube. Germination rates in A. niger, M. thermophila, and R. microsporuscultivated in solid state fermentation were affected by the substrate, incubationtemperature, and initial moisture. A mixture of sugar cane bagasse and wheat bran(80:20 w/w) resulted in high germination rates for all species tested, and was selectedfor additional experiments. The optimal temperature for spore germination and initialgrowth was 30 C for A. niger and 45 C for and 45 C for M. thermophila and R. microsporus. Highergermination rates were recorded in all species at 85% (aw 0.99) initial moisture after 6h of incubation at optimal temperature. Forced humid aeration increased germinationrates and decreased the time required for complete spore germination in all speciesstudied. 2007 artículo científico 1534-2581 https://www.redalyc.org/articulo.oa?id=68519101 en http://www.redalyc.org/revista.oa?id=685 Micología Aplicada International application/pdf Colegio de Postgraduados Micología Aplicada International (México) Num.1 Vol.19 |
