Thank you for your comment !
But because I used the same technique with UNvented jars and had no contamination, I`m wondering about those sterile wound dressing.... I covered only one side of the lid, maybe I should cover both side?
BTW, after I saw the contamination, I removed the protocorn, sterilized them in a H2O2 solution and then placed them in an unvented flask ! It`s been 4 days now and no sign of contamination.... ( finger crossed )
I don`t know if the protocorn will survive the H2O2 treatment.... will see !
