Biological Characteristics of One Penicillium Strain Producing Sclerotia
摘要
Abstract
Seventy-three strains of Penicillium were isolated from soil samples. One of them named Q1 could produce sclerotia. By observing its characteristics of colony and individual, strain Q1 was initially I-dentified to P. Thomii series. The results showed that the optimum culture temperature and pH for strain Q1 were 25 ℃ and 6.5 ,respectively. The best medium for Q1 producing sclerotia was malt extract agar me-dium. Among inorganic salts tested, single effect of K_2HPO_4 was best,which showed that K_2HPO_4 had ver-y important effect on sclerotial formation of strain Q1. Carbon and nitrogen sources in medium had signifi-cant effects on the sclerotial biomass of strain Q1. Maltose and yeast extract proved to be the best carbon and nitrogen sources respectively. The medium containing 0.24~0.48 g/L sodium nitrate-nitrogen and 20 g/L carbon concentration were effective to the sclerotial formation of Q1 strain.关键词
