Resumo: | The biofloc system (biofloc technology - BFT) has high efficiency in the production of aquatic organisms and with low polluting potential. Its principle is the heterotrophic bacteria growth, obtained by maintaining the carbon: nitrogen (C: N) ratio in the medium, which will transform undesirable componentes, such as ammonia and nitrite, into less toxic compounds and with some protein value. This system consists of maintaining the carbon: nitrogen ratio (C: N). The main constitution of bioflocs are microalgae, feces, exoskeletons, feed and dead animal remains, bacteria, rotifers, protozoa, other invertebrates, in complex interaction in the water column. This work aimed to evaluate the variation of water quality, the zooplanktonic biomass present in the BFT formed with three carbon: nitrogen ratios, as well as to verify diferences in maturation time among C: N ratios. The bioflocs were formed using refined sugar as a carbon source, three treatments were tested with different carbon: nitrogen ratios, 10: 1, 15: 1 and 20: 1. Ammonia, nitrite, nitrate, orthophosphate, alkalinity, temperature, dissolved oxygen and pH were measured at intervals of 3 to 4 days. The physical and chemical parameters of the water showed no significant differences between treatments, with the exception of orthophosphate, which showed a difference in treatment 20: 1. The maturation of the 20: 1 treatment occurred only 3 days after the maturation of the 10: 1 and 15: 1 treatment and the zooplanktonic density did not differ among treatments. It is recommended to use the 10: 1 carbon: nitrogen ratio, since there will be an economy in the amount of carbon offered to the medium and, consequently, a lower production cost. |

Su principio es el crecimiento de bacterias heterótrofas, obtenido con el mantenimiento de la relación carbono: nitrógeno (C: N) en el medio, que transformarán los componentes indeseables, como el amoníaco y el nitrito, en compuestos menos tóxicos con cierto valor proteico. La principal constitución de los bioflocs son las microalgas, las heces, los exoesqueletos, los restos de comida y de animales muertos, las bacterias, los rotíferos, los protozoos y otros invertebrados, en compleja interacción en la columna de agua. En este trabajo, el objetivo fue evaluar la variación de la calidad del agua, la biomasa de zooplancton presente en el BFT formado con tres proporciones de carbono: nitrógeno, así como verificar si existen diferencias en el tiempo de maduración entre las tres proporciones de C: N ensayadas. Los bioflocs se formaron utilizando azúcar refinado como fuente de carbono, se probaron tres tratamientos con diferentes proporciones de carbono: nitrógeno de 10:1, 15:1 y 20:1. El amoníaco, el nitrito, el nitrato, el ortofosfato, la alcalinidad, la temperatura, el oxígeno disuelto y el pH se midieron a intervalos de 3-4 días. Los parámetros físicos y químicos del agua no mostraron diferencias significativas entre los tratamientos, a excepción del ortofosfato, que mostró una diferencia en el tratamiento 20:1. La maduración del tratamiento 20:1 se produjo sólo 3 días después de la maduración de los tratamientos 10:1 y 15:1 y la densidad del zooplancton no difirió entre los tratamientos. Se recomienda utilizar la relación carbono: nitrógeno de 10:1, ya que habrá una economía en la cantidad de carbono ofrecida al medio ambiente, y en consecuencia, un menor coste de producción.O sistema de bioflocos (BFT) possui alta eficiência na produção de organismos aquáticos e com baixo potencial poluidor. Seu princípio é o crescimento de bactérias heterotróficas, obtido com a manutenção da relação carbono: nitrogênio (C: N) no meio, as quais irão transformar componentes indesejáveis, como a amônia e o nitrito, em compostos menos tóxicos e com algum valor proteico. A principal constituição dos bioflocos são microalgas, fezes, exoesqueletos, restos de ração e de animais mortos, bactérias, rotíferos, protozoários, outros invertebrados, em complexa interação na coluna d’água. Neste trabalho, objetivou-se avaliar a variação da qualidade da água, da biomassa zooplânctonica presente no BFT formado com três relações carbono: nitrogênio, bem como verificar se há diferenças no tempo de maturação entre as três relações C: N testadas. Os bioflocos foram formados utilizando açúcar refinado como fonte de carbono, foram testados três tratamentos com diferentes relações carbono: nitrogênio, de 10:1, 15:1 e 20:1. Amônia, nitrito, nitrato, ortofosfato, alcalinidade, temperatura, oxigênio dissolvido e pH foram medidos em intervalos de 3 a 4 dias. Os parâmetros físicos e químicos da água não apresentaram diferenças significativas entre os tratamentos, com exceção do ortofosfato, que apresentou diferença no tratamento 20:1. A maturação do tratamento 20:1 ocorreu apenas 3 dias após a maturação dos tratamentos 10:1 e 15:1 e a densidade zooplânctonica não diferiu entre os tratamentos. É recomendado utilizar a relação carbono: nitrogênio de 10:1, visto que haverá uma economia na quantidade de carbono oferecida ao meio, e consequentemente, um menor custo de produção.Research, Society and Development2022-07-03info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://rsdjournal.org/index.php/rsd/article/view/3119610.33448/rsd-v11i9.31196Research, Society and Development; Vol. 11 No. 9; e6311931196Research, Society and Development; Vol. 11 Núm. 9; e6311931196Research, Society and Development; v. 11 n. 9; e63119311962525-3409reponame:Research, Society and Developmentinstname:Universidade Federal de Itajubá (UNIFEI)instacron:UNIFEIporhttps://rsdjournal.org/index.php/rsd/article/view/31196/26944Copyright (c) 2022 Guido Luis Bianchini Dalke; Grace Kelly Goudinho Pires; Maria do Carmo Gominho-Rosa; Nyamien Yahaut Sebastien; Robie Allan Bombardellihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessDalke, Guido Luis Bianchini Pires, Grace Kelly Goudinho Gominho-Rosa, Maria do Carmo Sebastien, Nyamien Yahaut Bombardelli, Robie Allan 2022-07-21T12:36:16Zoai:ojs.pkp.sfu.ca:article/31196Revistahttps://rsdjournal.org/index.php/rsd/indexPUBhttps://rsdjournal.org/index.php/rsd/oairsd.articles@gmail.com2525-34092525-3409opendoar:2024-01-17T09:47:38.141956Research, Society and Development - Universidade Federal de Itajubá (UNIFEI)false |
