Role of Chlorella sp. and rhamnolipid 90 in maintaining homeostasis in soil contaminated with bisphenol A

摘要: The knowledge about the impact of BPA on soil health does not correspond to great interest in its analogues. Therefore, a study was conducted determine potentially negative biochemical properties soil. also evaluated effectiveness two biostimulants eliminating potential homeostasis disorders caused by BPA. A pot experiment under supervised conditions. at five contamination levels added granulometric composition sandy loam 0, 0.1, 2, 40 and 800 mg kg−1 dry matter (DM) activity interpreted through dehydrogenases (Deh), urease (Ure), catalase (Cat), acid phosphatase (Pac), alkaline (Pal), arylsulphatase (Aryl) β-glucosidase (Glu) whose determined days 5, 15 45 study. biostimulative Chlorella sp. rhamnolipid 90 (which eliminates undesirable effects parameters) expressed with IFB—the factor increasing bisphenol (BP) levels. response spring barley pressure analysed plant resistance index (RS). made more comprehensive determination macronutrient content plants. sensitivity individual enzymes 45th day can be arranged following sequence: Deh > Ure Glu Pac Cat Aryl Pal. Biostimulation gave better results than 90. compilation DM brought an increase Pac, Pal 5th day. Only this level did stimulate crop growth all parallel plots except those biostimulated algae significantly reduced N, Ca K barley. emphasised significant inhibitory which, consequence, upset microbial balance processes. played important role maintaining 90, which yield
