Efficient nutrient and antibiotics removal from aquaculture wastewater using different microalgae-based systems by agricultural multi-phytohormone induction
The present study innovatively explores the impact of adding agricultural mixed plant hormones (gibberellin acid-indole-3-acetic acid-brassinolide, GIB) on simultaneously removing nutrients and antibiotics out of aquaculture wastewater within different four microalgae-bacteria-fungus symbionts. The results indicated that under the optimal symbiotic technology (Chlorella vulgaris+S395-2+Clonostachys rosea) and the best hormone GIB (20 mg L−1) addition, both growth characteristics and photosynthetic performance of microalgae-bacteria-fungus symbionts were optimal. Under optimal treatment conditions, the average nutrient removal efficiency (TN and TP) reached 93.71 ± 5.02 % and 93.56 ± 4.07 %, separately, whereas the average removal efficiency of antibiotics (oxytetracycline, ciprofloxacin and sulfadiazine) were 99.46 ± 0.17 %, 89.53 ± 5.41 %, and 85.68 ± 6.82 %, respectively. This study offers a promising new direction for algal treatment technology, particularly in the concurrent removal of antibiotics and nutrients.
期刊介绍:
Algal Research is an international phycology journal covering all areas of emerging technologies in algae biology, biomass production, cultivation, harvesting, extraction, bioproducts, biorefinery, engineering, and econometrics. Algae is defined to include cyanobacteria, microalgae, and protists and symbionts of interest in biotechnology. The journal publishes original research and reviews for the following scope: algal biology, including but not exclusive to: phylogeny, biodiversity, molecular traits, metabolic regulation, and genetic engineering, algal cultivation, e.g. phototrophic systems, heterotrophic systems, and mixotrophic systems, algal harvesting and extraction systems, biotechnology to convert algal biomass and components into biofuels and bioproducts, e.g., nutraceuticals, pharmaceuticals, animal feed, plastics, etc. algal products and their economic assessment
