Resumo: | This work aimed to evaluate the filtering capacity of inorganic nitrogen and phosphorus by biofilter of the macroalgae Ulva lactuca as a function of stocking density in an AMTI system in water recirculation. The macroalgae were cultivated in 20 experimental units, with 5 stocking densities (2, 4, 6, 8 and 10 kg.m-3) and 4 replications. The concentrations of the nutrients ammonia (N-NH3), nitrite (N-NO2), nitrate (N-NO3) and phosphate (P-PO4) were analyzed at the time of interruption of supply (06:00) and after 12 hours (18:00) for evaluation of nutrient filtration. There were no significant variations (p>0.05) between the values of filtration efficiency of nitrogen (EF-N) and phosphorus (EF-P) and of the filtration rate of nitrogen (TF-N) and phosphorus (TF- P) as a function of stocking density. However, an effect (p<0.05) of stocking density on the filtration index of nitrogen (IF-N) and phosphorus (IF-P) was observed, where the highest indexes were observed for the lowest stocking densities. The macroalgae storage density interferes with the nutrient filtration capacity, where lower storage densities provide greater macroalgae filtration capacity. |

Las macroalgas se cultivaron en 20 unidades experimentales, con 5 densidades de almacenamiento (2, 4, 6, 8 y 10 kg.m-3) y 4 repeticiones. Las concentraciones de los nutrientes amonio (N-NH3), nitrito (N-NO2), nitrato (N-NO3) y fosfato (P-PO4) se analizaron en el momento de la interrupción del suministro (06:00) y después de las 12 horas (18:00) para la evaluación de la filtración de nutrientes. No hubo variaciones significativas (p> 0.05) entre los valores de eficiencia de filtración de nitrógeno (EF-N) y fósforo (EF-P) y de la tasa de filtración de nitrógeno (TF-N) y fósforo (TF-P ) en función de la densidad de población. Sin embargo, se observó un efecto (p <0.05) de la densidad de población sobre el índice de filtración de nitrógeno (IF-N) y fósforo (IF-P), donde se observaron los índices más altos para las densidades de carga más bajas. La densidad de almacenamiento de las macroalgas interfiere con la capacidad de filtración de nutrientes, donde las densidades de almacenamiento más bajas proporcionan una mayor capacidad de filtración de las macroalgas.O presente trabalho buscou avaliar a capacidade de filtração de nitrogênio e fósforo inorgânicos por biofiltro da macroalga Ulva lactuca em função da densidade de estocagem em sistema de AMTI em recirculação de água. As macroalgas foram cultivadas em 20 unidades experimentais, com 5 densidades de estocagem (2, 4, 6, 8 e 10 kg.m-3) e 4 repetições. As concentrações dos nutrientes amônia (N-NH3), nitrito (N-NO2), nitrato (N-NO3) e fosfato (P-PO4) foram analisadas no momento da interrupção do abastecimento (06:00) e após 12 horas (18:00), para avaliação da filtração de nutrientes. Não foram observadas variações significativas (p>0,05) entre os valores da eficiência de filtração de nitrogênio (EF-N) e fósforo (EF-P) e da taxa de filtração de nitrogênio (TF-N) e fósforo (TF-P) em função da densidade de estocagem. Porém, foi observado efeito (p<0,05) da densidade de estocagem sobre o índice de filtração de nitrogênio (IF-N) e fósforo (IF-P), onde os maiores índices foram observados para as menores densidades de estocagem. A densidade de estocagem da macroalga interfere na capacidade de filtração de nutrientes, onde as menores densidades de estocagem proporcionam maior capacidade de filtração da macroalga.Research, Society and Development2022-02-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/2617310.33448/rsd-v11i3.26173Research, Society and Development; Vol. 11 No. 3; e14111326173Research, Society and Development; Vol. 11 Núm. 3; e14111326173Research, Society and Development; v. 11 n. 3; e141113261732525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/26173/23093Copyright (c) 2022 Ricardo de Oliveira Soares; Beatriz Castelar; Marcelo Duarte Ponteshttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessSoares, Ricardo de Oliveira Castelar, Beatriz Pontes, Marcelo Duarte 2022-03-09T13:44:38Zoai:ojs.pkp.sfu.ca:article/26173Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:44:16.740640Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
