Item Estágio supervisionado obrigatório na empresa doces união, manejo do coco, mamão, e produção na agroindústria de doces(2019-12-04) Silva, Raí Carlos da; Pereira, Rodrigo Gomes; http://lattes.cnpq.br/5651953026655989; http://lattes.cnpq.br/2144205669930867The present work is a report of the activities carried out during the Compulsory Supervised Internship (ESO) carried out at the company Doces União in the União dos Palmares municipality in the state of Alagoas from November to December 2018. During this time it was possible to follow the culture of the coconut, papaya, and the candy industry. Accompanying cultural treatments such as: Coconut: crowning, irrigation, fertilization, pest and weed control, commercialization. Papaya: irrigation, fertilization, sexing, pest and weed control, commercialization; Also received were receptions of raw materials, such as guava and banana, and production flow charts for processing in agro-industry. The internship enabled the contact with the job market, providing a greater perception of business management, adding to the professional team leadership spirit and solving adverse problems, allowing to broaden knowledge in the production of coconut and papaya culture, in addition to agribusiness; thus contributing positively to work in the labor market. The ESO was of fundamental importance as it provided invaluable personal and professional growth in student life.Item Influência de fatores abióticos sobre o desenvolvimento de bactérias promotoras de crescimento vegetal dos gêneros Bacillus e Pantoea(2019-02-05) Amorim, Alyson da Silva; Sobral, Júlia Kuklinsky; http://lattes.cnpq.br/8273377142633220; http://lattes.cnpq.br/9204041210789535Incorrect handling during the application of most agricultural pesticides has been causing contamination in soils, groundwater, fauna and flora in Brazilian agroecosystems, in addition to increasing costs in agricultural production. The microbiota when subjected to dosages above the recommended level of certain pesticides suffers deleterious effects on their populations. And as a way to reduce input costs and the search for more sustainable agricultural production, the use of growth promoting bacteria and bioremediators is a biotechnological tool of great potential. Another factor that influences agricultural production is salinity. It is a term that qualifies a situation of excess soluble salts in the environment. This problem is one of the main causes of soil degradation in regions of arid and semi-arid climate, culminating in serious agricultural income. To contribute to the recovery of these degraded soils, plant growth promoting bacteria have been shown to be useful in the development of strategies to promote plant growth in saline soils. In view of the above, the present work had as objectives: i) to evaluate the tolerance to the methomyl pesticide and the potential biodegradation capacity of this pesticide by Bacillus plant growth promoting bacteria; and ii) to evaluate the production of exopolysaccharides under saline stress by plant growth promoting bacteria of the genus Pantoea. For the evaluation of pesticide tolerance, the Bacillus bacteria (UAGAT35 and UAGAT71). were inoculated in modified Minimal Mineral Medium (MMM), plus glucose as carbon source, followed by different concentrations of Methomyl. And to assess the potential for biodegradation, the carbon source has not been increased. In the experiment on salinity, five bacterial strains of the genus Pantoea were used (UAGC 906, UAGC 977, UAGC 858, UAGC 907 and UAGC 972), which were grown in solid medium with sucrose and added different concentrations of NaCl in each tr. For 10 days, the growth of the halo was measured with the aid of a pachymeter, being done five readings, in intervals of 48 hours. The two strains of the genus Bacillus demonstrated tolerance and biodegradation to methomyl insecticide, in their different concentrations. While the 5 bacterial strains of the genus Pantoea submitted to the different concentrations of NaCl presented production of Exopolysaccharides (EPS), showing their survival in environments under IX salt stress. Therefore, the evaluated bacteria presented potential for future studies aiming to promote growth in adverse environments.
