There is some evidence that hemicellulose is higher in 13C than cellulose in wood. Perhaps some differences in d13C of wood decay fungi reflect preferences for cellulose versus hemicellulose attack and assimilation.
Never came across such fungus species. It's either they decay the wood carbohydrates and lignin simultaneously (in the case of simultaneous white rot) or they attack the carbohydrate fractions alone (brown rot and soft rot). The selective white rot fungi also attacks hemicellulose together with lignin, so no fungus species for now as been reported to attack hemicellulose in isolation.
OK, thanks. It's the selective white rotters I'm interested in. Whether they also attack lignin as well as hemicellulose does not matter in terms of my interests.
I think so! I have some experiences like, I extracted hemicellulose and lignin and I saw fungus attract in the next couple of days unless I controlled the temperature or really low pH.
Thanks. So they like the cellulose you left behind, it sounds like. There seems to be a reasonable amount of literature on this, once I started digging deeper.
