[About the Pleurotus ostreatus] Is it contaminated by mold? or mushroom mycelium? please help me.
Hello, respect expert.
I carried out the cultivation of Pleurotus ostreatus tissue through the PDA (Potato dextrose agar),
before 3 days ago. ( from July 19 ~ July 22) and today I could find something change.
but I cannot know that was infected by white mold or growth mushroom mycelium.
after look my upload picture, please help me..
P.S) I am not English-speaker. sorry so much about my rough English. (I am S. Korean)
The picture appears to show white mycelium of a fungus growing, and it does not look like another fungus in combination or as a contaminant. Pleurotus would grow white like what you see. I cannot tell without microscopic examination. Keep the lids of the petri dishes closed and wait a few days to see if it look like there are two organisms growing.
Thank you for contacting Cooperative Extension,
Thank you so much expert. ^^
Actually I did this experiment for isolation of Pleurotus mycelium.
I could take the help from your comment in many part.
I will follow your teaching.
