El objetivo de este estudio fue evaluar in vitro la capacidad de los hongos rizosféricos aislados del cactus Opuntia cochenillifera para promover el crecimiento de las plantas. Los aislados fueron sometidos a pruebas de solubilización de fosfato, producción de ácido 3-indol acético (AIA), antagonismo contra fitopatógenos y crecimiento bajo actividad de agua. Todos los resultados de las pruebas se sometieron a análisis estadístico. Los aislados estudiados fueron capaces de solubilizar fosfato, siendo F04 (Aspergillus sp.) y F05 (Coprinellus radians) los que presentaron los mayores índices de solubilización. Sobre la producción de AIA, los que más produjeron fueron F02 (Penicillium sp.) y F07 (Aspergillus sp.). Todos los aislados pudieron inhibir el crecimiento de Colletotrichum sp. e Fusarium sp.. La restricción de agua proporcionó el crecimiento del micelio para todos los aislados. Por lo tanto, estes aspectos les confieren características como promotores del crecimiento en las plantas.

Raw milk is a food with great consumption and economic value in Brazil. However, is susceptible of contamination by pathogenic bacteria. The aimed of this study was to evaluate the quality of in natura milk based on microbiological in three dairy farms, somatic cells counting (SCC), bacterial counting and his physical-chemical composition. Were made the following microbiological analysis: counting of mesophilic and psychrotrophic bacteria, coliforms at 30 ºC, coliforms at 45 ºC, Staphylococcus spp., Listeria spp., and SCC. The physical-chemical analysis was fat, protein, lactose, total solids, urea, and casein. There was no evidence of Salmonella spp. and Escherichia coli were identified in any samples. In accordance to the microbiological standards established by Normative Instruction 76 only coliforms 30 ºC and 45 ºC counts were above the standards. There was a significant difference (p≤0.05) between the three farms studied regarding most microbiological aspects. Also, was observed difference (p≤0.05) for most of physical-chemical aspects. Overall, the milk produced in the regions of Alagoas State fails to meet just a constant criterion in the current legislation.

A abordagem de Imobilização celular por microencapsulação se destaca como uma alternativa altamente eficaz na condução de bioprocessos. Ao encapsular as células em microcápsulas, cria-se uma matriz tridimensional que proporciona retenção celular prolongada. Com base nesse contexto, objetivou-se avaliar a imobilização de isolados de Trichoderma em alginato de cálcio e avaliar a viabilidade e determinar a temperatura ideal para armazenar os fungos imobilizados. Para produção dos grânulos foram utilizados amido e alginato de sódio, que juntamente com cada isolado foi gotejado em solução de cloreto de cálcio. Para avaliar a viabilidade dos fungos encapsulados e a melhor condição de armazenamento, foram realizados testes com os grânulos armazenados nas temperaturas ambiente, geladeira e freezer. Foi possível obter cápsulas de alginato íntegras, e a avaliação da concentração dos conídios durante 21 dias de armazenamento em diferentes ambientes mostrou que os mesmos se mantiveram viáveis (107 conídios g-1).

Objective: The objective of this study was to evaluate the breeding of domestic animals in households of Alagoas-BR during the pandemic. Theoretical Reference: Zootechnology is the science that aims to harness the potential of domestic animals, with the purpose of exploiting them rationally as a source of food and other purposes with humans, adapting animals to the creative environment and thus harnessing them for nutritional and economic purposes. Domestic animals, in turn, are of great importance in society, from those intended for human consumption, as well as those tutored for domestic companionship and other purposes such as accompanying persons with special needs. Method: The search was performed by collecting data, constituting a quantitative search, through a questionnaire on Google Forms. The study's actors were students from the ECSC-UFAL. Through the answers, it was identified that the majority of the participants corresponded to students of the Zootechny course. Results: The majority of respondents reside in the urban area, being 82.5% residents of houses. Of the total, 42.6% stated that they had as monthly income per capita up to 1.5 minimum wages. Twelve types of animals were cited and 72.1% of the participants did not start breeding a new animal during the pandemic, of the 27.9%, most of the animals were obtained by adoption. With the main reason being financial, 5 of the interviewees claimed that they had to donate the animal during the pandemic. Eight interviewees raise animals for consumption, including cattle, chickens, pigs, sheep and goats. Only 7.7% sought the help of a zootechnician to assist in the rearing of these animals. However, even being a low percentage, it is understood that all participants know the role of the zootechnician in animal breeding. Implications of research: For the professional practice of the zootechnician, it is indispensable to have a holistic understanding of all the factors and phenomena around him. This perception begins in his education as a student and his experiences and experiences contribute to the result (professional activity). Originality/value: The results presented here as the result of the research deal with unprecedented and relevant data for studies especially within the area of agrarian and related sciences, since it raises perceptions of students as to their course, as well as these actors tend to represent their understandings to the external public. It also implies the need for a better understanding of the importance of domestic animals going beyond breeding for consumption and/or simple companionship to guardians.

Nas últimas décadas, a suinocultura brasileira passou por processos de modernização em vários segmentos da produção, atingindo índices técnicos e econômicos semelhantes e, algumas vezes, melhores aos obtidos em países mais tradicionais na criação. Apesar da região Nordeste ser detentora do segundo maior rebanho suíno do Brasil, ainda são encontradas explorações informais, sem controle efetivo da produção e com condições higiênico-sanitárias duvidosas, tornando um ponto negativo no momento da escolha da carne e seus derivados, o que incide sobre o baixo consumo na região. Objetivou-se com esse estudo avaliar as condições higiênico sanitárias de carne suína comercializada em feiras livres do vale do Paraíba. Foram coletadas 20 amostras obtidas em feiras livres de quatro municípios do vale do Paraíba. As amostras foram coletadas assepticamente em recipientes estéreis e acondicionados em caixa isotérmica, contendo gelo reciclável, e encaminhadas ao Laboratório para análises. Foram observadas contagens elevadas de micro-organismos aeróbios mesófilos, variando de 2,5x106 UFC/g, e encontrados coliformes a 45ºC acima dos valores permitidos pela legislação em 80% das amostras, verificou-se a presença de Staphylococcus coagulase positiva em 25% das amostras. Assim, as condições higiênico-sanitárias da carne suína proveniente de feiras livres de municípios do Vale do Paraíba, Alagoas, podem refletir a maneira como são submetidas à manipulação e comercialização. Além disso, a exposição prolongada desse alimento sem qualquer tipo de refrigeração, contribui para elevados níveis de contaminação microbiana, podendo provocar riscos de toxinfecções alimentares, deterioração e perda da qualidade da carne para o consumidor final.
