- Аннотация: Microalga Chlorella (Chromochloris) zofingiensis has been gaining increasing attention of investigators as a potential competitor to Haematococcus pluvialis for astaxanthin and other xanthophyllsproduction. Phytohormones, including abscisic acid (ABA), at concentrations relevant to that inhydroponic wastewater, have proven themselves as strong inductors of microalgae biomass productivity and biosynthesis of valuable molecules. The main goal of this research was to evaluate theinfluence of phytohormone ABA on the physiology of C. zofingiensis in a non-aseptic batch experiment.Exogenous ABA stimulated C. zofingiensis cell division, biomass production, as well as chlorophyll,carotenoid, and lipid biosynthesis. The relationship between exogenous ABA concentration and themagnitude of the observed effects was non-linear, with the exception of cell growth and biomassproduction. Fatty acid accumulation and composition depended on the concentration of ABA tested.Exogenous ABA induced spectacular changes in the major components of the culture microbiomeof C. zofingiensis. Thus, the abundance of the representatives of the genus Rhodococcus increaseddrastically with an increase in ABA concentration, whereas the abundance of the representatives ofReyranella and Bradyrhizobium genera declined. The possibilities of exogenous ABA applications forthe enhancing of the biomass, carotenoid, and fatty acid productivity of the C. zofingiensis culturesare discussed
