Raw data of publication: Lead biosorption and chemical composition of extracellular polymeric substances isolated from mixotrophic microalgal cultures

The deposited data were collected within the research project entitled ‘Określenie warunków syntezy, składu chemicznego i właściwości zewnątrzkomórkowych polimerów (EPS) wytwarzanych przez wybrane jednokomórkowe glony’ (eng.: ‘Determining of the conditions of synthesis, chemical composition, and properties of extracellular polymers (EPS) produced by selected unicellular algae’). The research was financed by the National Science Centre, Poland as part of the project under the PRELUDIUM 22 (project no.: 2023/49/N/NZ9/03415) and SONATA 12 (project no.: 2016/23/D/NZ9/02670).The main objective of the research was to evaluate the influence of mixotrophic cultivation of microalgae on the EPS productivity and chemical composition, and to determine the sorption potential of EPS extracted from mixotrophic cultures.The research was conducted at the Institute of Agrophysics, Polish Academy of Sciences in Lublin (Poland). The collection contains EPS productivity, EPS chemical composition, sorption studies, FTIR analysis of EPS from autotrophic and mixotrophic cultures, EPS from mixotrophic cultures after pH modification and pH-modified EPS after Pb(II) sorption).The attached files have been compressed to *.zip format. The dataset consists of the following files:A_1.zip – raw data on the EPS productivity and chemical composition (.xlsx, .jpg);A_2.zip – raw data on the FTIR spectra of EPS (.xlsx, .spa);Pb_sorption.xlsx – raw data on the Pb(II) sorption (.xlsx).The data was compiled based on laboratory tests. The results were obtained using the following research equipment: spectrophotometer Carry 300, FTIR Spectrometer Nicolet 6700, ICP-OES iCAP 6500 Duo. Software: Statistica, Omnic, OriginPro.
