Additional information

Under the conditions of the present study with Pseudokirchneriella subcapitata, 4,4’-Isopropylidenediphenol, oligomeric reaction products with 1-chloro-2,3-epoxypropane, reaction products with butan-1-ol and 3-aminomethyl-3,5,5-trimethylcyclohexylamine reduced growth rate and inhibited the yield of this fresh water algae species significantly at nominally 3.2 mg/l and higher.
