Bukov ostrigar - strupena ali užitna goba? (ZmK-13)

from Znanost na cesti · host Science on the street

Bukov ostrigar je užitna in celo zdravilna goba, ki jo lahko najdemo v naravi, brez večjih težav pa jo lahko gojimo tudi doma. Leta 2002 so iz bukovega ostrigarja izolirali protein ostreolizin, za katerega se je izkazalo, da v zelo nizkih koncentracijah povzroča funkcionalne in morfološke spremembe pri različnih tipih celic. Molekulski mehanizem delovanja je tvorba por v membranah celic sesalcev, posledica toksičnega učinka ostreolizina pa je lahko celo kardio-respiratorni zastoj. Postavljajo se vprašanja kot so, ali naj še jemo omako z bukovim ostrigarjem? V kakšnih pogojih je lahko ta goba vseeno nevarna za nas? Kako bi lahko, glede na znane učinke in mehanizme delovanja ostreolizina, le-tega koristno uporabili?
