title: The quality of protein from algae used in the purification of wastewater from the nitrogen fertilizer industry.
abstract: This paper presents the quantities and amino acid composition of proteins from Chlorella vulgaris, Scenedesmus obliquus and Stichococcus bacillaris used in purification experiments on wastewater from the Nitrogen Fertilizer Factory in Chorzów. The quantities of exogenous amino acids of the investigated algae and "ideal protein" standard of the FAO are compared. The protein from Scenedesmus and Chlorella appeared to be richer in exogenous amino acids than the FAO standard. Stichococcus bacillaris has a lower content of exogenous amino acids but nevertheless has a high content of threonine and lysine, higher than in the other investigated algae.
