tailieunhanh - Biostimulant and biopesticide potential of microalgae growing in piggery wastewater

Pig farming generates highly polluting wastewaters which entail serious environmental issues when not adequately managed. Microalgae systems can be promising for cost, energy and environment-efficient treatment of piggery wastewater (PWW). Aside from clean water, the produced biomass can be used as biostimulants and biopesticides contributing to a more sustainable agriculture. | Environmental Advances 4 2021 100062 Contents lists available at ScienceDirect Environmental Advances journal homepage locate envadv Biostimulant and biopesticide potential of microalgae growing in piggery wastewater Alice Ferreira a Lusine Melkonyan b c Sofia Carapinha a Belina Ribeiro a Daniel Figueiredo d Gayane Avetisova b c Luisa Gouveia a d a LNEG National Laboratory of Energy and Geology .

Microalgae systems can be promising for cost energy and environment-efficient treatment of Cyanobacteria piggery wastewater PWW . Aside from clean water the produced biomass can be used as biostimulants and Swine wastewater biopesticides contributing to a more sustainable agriculture. Germination index Plant protection Three microalgae Tetradesmus obliquus Chlorella protothecoides Chlorella vulgaris and one cyanobacterium Syne- chocystis sp. were selected after a preliminary screening in diluted wastewater 1 20 to treat PWW. The nutrient removals were 62-79 for COD chemical oxygen demand 84-92 for TKN total Kjeldahl nitrogen 79-92 for NH4 and over 96 for PO4 3 . T. obliquus and C. protothecoides were the most efficient ones. After treating PWW the produced biomass at g L 1 was assessed as a biostimulant for seed germination root shoot growth and pigment content for tomato watercress cucumber soybean wheat and barley seeds. We observed an overall increase on .
