Extracellular enzyme production and phylogenetic distribution of yeasts in wastewater treatment systems

► We isolated 257 yeasts from five different wastewater treatment systems. ► The abilities of the yeasts to produce extracellular enzymes were detected. ► The yeasts mainly produced lipase, protease, MnP and LiP. ► The enzyme producing yeasts had diverse phylogenetic distribution. ► The types of enzymes produced by yeasts were related with isolation sources.
