it's my first time to extract DNA from ganoderma lucidum mycelium and I have read that CTAB method doesn't give pure DNA and there is A kit called DNAeasy kit that is good.
I've been using CTAB method for fungal DNA extraction. I usually have purity ranging 1.8 to 2.0 and concentration up to 1000ng/uL. It all boils down on how careful you are during the phenol:chloroform:isoamyl alcohol step.
