| contents | Lignin degradation products from corn stalks enhance notably the radial growth of basidiomycete mushroom mycelia Miguel J. Beltrán García Aideé Orozco Ivan Samayoa Tetsuya Ogura Multidisciplinaria (Ciencias Naturales y Exactas) Pleurotus corn stalk Basidiomycetes growth promotion ligninderived phenols Milled corn stalk (crude) was cleaned by diverse solvents(cleaned). When 1000 ppm of cleaned was added to Peptone /Glucose / Agar (PGA), the growth rate of Pleurotus ostreatus andPleurotus sajor-caju was doubled. The mycelial diameter alsoincreased by a supplementation of a hot water extract of cleaned correspondingto 1000 ppm, which was composed of 400 mg / g-stalk ofnonvolatile compounds including 60 mg / g-stalk of phenolicmonomers. An IR spectrum of the extract was very similar to that ofcleaned and commercial lignin. Supplementation of crude or cleanedto Malt extract / Sucrose / Agar (MSA) promoted mycelial growth by30 % in all five basidiomycete studied. A commercially availableKraft lignin supplemented to MSA showed cleaned-like growth promotions.The hot water extract showed growth promotion to themycelia at a range of 106-107 M as seen in plant hormones.Therefore, we suggest these fungi use the enzymatic degradationproducts of lignin as a signal to faster mode of growth. This must bean important tactic of the fungi in securing their niche by degrading avegetal biomass before competitors encroach upon it. 2001 artículo científico 1870-249X https://www.redalyc.org/articulo.oa?id=47545207 en http://www.redalyc.org/revista.oa?id=475 Journal of the Mexican Chemical Society application/pdf Sociedad Química de México Journal of the Mexican Chemical Society (México) Num.2 Vol.45 |
