Resumo - O presente artigo aborda de forma resumida as bases gerais da biotécnica de Manipulação de Oócitos Inclusos em Folículos Ovarianos Pré-antrais (MOIFOPA) com ênfase nos estudos relativos ao desenvolvimento de um ovário artificial na espécie caprina. A importância do ovário artificial para a elucidação da foliculogênese inicial, testes de drogas sobre a dinâmica folicular e a sua potencial utililização para a produção in vitro de embriões em larga escala respeitando-se o bem-estar animal é destacada. Development and applications of artificial ovary in goats. Abstract - The present paper summarizes the basic aspects of the biotechnology of manipulation of oocytes enclosed in ovarian preantral follicles emphasizing the studies to develop an artificial ovary in goat species. The importance of the artificial ovary for the understanding of early folliculogenesis, evaluation the effects of different drugs on follicular dynamics and its potential use for the in vitro production of embryos in large scale ensuring the animal welfare is highlighted. |

Abstract: Digestate from anaerobic processes still contains relatively high amount of total organic carbon (TOC) that can inhibit deammonification. In this sense, the present study investigated the interference of TOC in a lab-scale expanded granular sludge bed (EGSB) deammonification reactor treating digestate from a continuous stirred tank reactor (CSTR) swine sludge biodigester. Additionally, the microorganisms community was analyzed when the process was submitted to different operational conditions. The study was divided into three phases according to the C/N ratio (0, 0.5 and 1 for phase I, phase II and phase III, respectively). At phase I the average nitrogen removal efficiency (NRE) was 65 ± 1.6%. With the increase of TOC in phase II (156 ± 8.15 mg L −1) the average NRE was 61 ± 9.8% which is statically equivalent to phase I (p < 0.05). On the other hand, at phase III (TOC was increased to 255 ± 3.50 mg L −1) the NRE decreased to 50 ± 3.9% which was 22% lower than in phase II. Stoichiometric coefficients of N 2 was close to theoretical values during all experimental phases, while stoichiometric coefficient of N-NO 3-was lower than theoretical values specially during phase III. Ca. Jettenia was favored when the reactor was fed with digestate although its proportion decreased in phase III. Thus, at the conditions employed in the present study it is recommended to use a C/N ratio of 0.5 (TOC concentration around 156 mg L −1) to treat digestate by deammonification process, in order to not diminish anammox microorganisms abundance. Thereby, the microorganisms community can be modulated based on carbon and nitrogen loading rates of a deammonification reactor for swine manure treatment purpose.
