Biodegration and degradation of methylene blue dye by S. elongatus



Dye-containing wastewater discharged from textile industries poses serious threats to aquatic biodiversity and human health. However, traditional physio-chemical methods for treating textile wastewater require high costs and produce secondary waste. Our project aims to investigate the bioremediation of textile dyes by expressing five selected ligninolytic enzymes from three different fungal species in the cyanobacterium S. elongatus, using methylene blue (MB) as a model substrate. Our in silico analyses have demonstrated MB degradation potential for all proteins of interest, suggested by their ability to form stable complexes with MB.
