Study on colony morphological characteristics and growth rate of Pochonia chlamydosporia
The purpose of this experiment was to study the growth rate of five Pochonia chlamydosporia strains in China,screen the most suitable solid media for growth and record the colony morphology characteristics on four solid media.Five strains of bacteria were inoculated in potato sucrose medium(PDA),and the colony diameter was measured to compare the growth rate of the five strains.Five strains of bacteria were inoculated on Sha's medium(SM),PDA medium,corn flour agar medium(CMA)and nutrient agar medium(NA),respectively.The colony diameters of each group were compared,and the characters of colony grown by each strain on different media were observed.The results showed that the growth rate of the five strains on PDA was Pc 30601>Pc 30612>Pc 30611>Pc 30603>Pc 81921,and the growth rate on the four media was SM>PDA>CMA>NA.The colony appeared white,milky white,light yellow and deep yellow on the front and yellow on the back.The study indicated that Pc 30601 had the highest growth rate among the five strains,and SM medium was the most suitable medium for Pc 30601 among the four media.
