Application of Urine as Fuel in a Soil-based Membrane-less Single Chamber Microbial Fuel Cell CIGR Journal
Simeon, Meshack Imologie; Otache., Matins Yusuf; Ewemojie, Temitayo Abayomi; RAJI, AbdulGaniy Olayinka.
Microbial fuel cell (MFC) technology is a promising bio-technology that utilizes the microorganism in organic wastes to generate electricity. Although human urine has been identified as a suitable substrate in MFCs, its possible utilization in a soil-based Membrane-less Single Chamber Microbial Fuel Cell (MSCMFC) for constant power generation has, hitherto, not been reported. In this study, a MFC was set up with mud as inoculums in a plastic cylindrical vessel using carbon felt electrodes. It was operated for 19 days (456 hours) without extra substrate. Then, the MFC was treated with human urine (as substrate) four times (Days 19, 24, 32 and 36) each time the MFC output stabilized across external loads. A control MFC (MFCcontrol) was made the same way and...

Avaliacao das perdas e qualidade de sementes na colheita mecânica de soja. Repositório Alice
COSTA, N. P. da; MESQUITA, C. M.; HENNING, A. A..
A colheita mecanica da soja acarreta perda de sementes que sao deixadas na superficie do solo. Alem disso, os impactos dos mecanismos da colhedeira sobrea semente afetam a sua qualidade fisiologica, de imediato ou de forma gradativa, durante a armazenagem. Visando avaliar a dimensao desses fenomenos, buscou-se determinar os indices de perdas na colheita mecanica e avaliar os efeitos desse processo sobre a qualidade fisiologica das sementes, em tres niveis de umidade. Apos seis meses de armazenamento, foi reavaliada a qualidade fisiologica das amostras e tambem comparados os niveis de infeccao das sementes colhidas manual e mecanicamente. Os dados foram levantados em 41 propriedades das principais regioes produtoras do Estado do Parana. Em cada propriedade,...

CHOUDHURY, M. M.; ARAUJO, E..
A patologia de sementes no Brasil embora sendo uma ciencia nova, ja conquistou o seu espaco, e hoje, sem duvida, e um dos segmentos da fitopatologia que mais intensamente tem atuado. Nas diferentes regioes do pais verifica-se que tem havido uma conscientizacao cada vez maior da sua importancia. As condicoes climaticas das regioes aridas e semi-aridas nao favorecem a incidencia de muitas fitomolestias. Constatou-se que as sementes de varias culturas produzidas no vale do Sao Francisco do Nordeste brasileiro apresentaram baixa incidencia de fitopatogenos transmitidos por sementes. Embora as condicoes climaticas destas regioes nao favorecem a ocorrencia de muitas fitodoencas, sementes produzidas nestas regioes nao estao totalmente livres de fitopatogenos e/ou...

Diversity and characterization of ramie-degumming strains Scientia Agricola
Duan,Shengwen; Liu,Zhengchu; Feng,Xiangyuan; Zheng,Ke; Cheng,Lifeng; Zheng,Xia.
Ramie (Boehmeria nivea and Boehmeria tenacissima) is a widely used fiber crop. Traditional water retting or chemical boiling method performed in order to extract ramie fiber seriously pollute the environment and severely damage the fiber, so biological method is the general trend of the fiber-extracting industry. Some strains (687), involving 26 genera and 43 species, were collected from the three samples, which produce hydrolyzed circles in the selective culture medium in order to detect the degumming effect and to compare the enzyme activity. Among these strains, 13 of them did not produce cellulase and had a ramie decreasing weight rate above 25 %, which were regarded as efficient ramie-degumming strains named from R1 to R13. R1 to R13 belonged to...

Electrolytic treatment and biosurfactants applied to the conservation of Eugenia uniflora fruit Ciênc. Tecnol. Aliment.
DILARRI,Guilherme; SILVA,Vinicius Luiz da; PECORA,Hengli Barbosa; MONTAGNOLLI,Renato Nallin; CORSO,Carlos Renato; BIDOIA,Ederio Dino.
Abstract Microorganisms are the primary responsible for food poisoning and food spoilage. The purpose of this study was to evaluate different fruit washing methods with tap water, electrolyzed water and rhamnolipids solution produced by Pseudomonas aeruginosa LBI, in order to inhibit microbial growth. The tested organism was Eugenia uniflora. The fruits were washed and periodically inoculated into culture media to evaluate and count the colonies on the fruit surface. It was also observed the deterioration level of the fruits after each treatment. The results showed that treatment with rhamnolipids were the most efficient, inhibiting the growth of fungi and bacteria. The electrolyzed water proved to be very efficient in bacterial inhibition at the initial...

Wang,Lichao; Guan,Lihui; Fang,Jiachen; Cai,Yimin; Cao,Yang.
ABSTRACT In this study, we examined the effects of lactic acid bacteria (LAB) inoculant and beet pulp (BP) on the quality of yacon (Smallanthus sonchifolius) residue silage. Yacon silage was prepared using a small-scale system of silage fermentation, and the treatments were as follows: control silage without any additive and silages with LAB inoculant Chikuso-1 (Lactobacillus plantarum, 5 mg/kg, fresh matter basis), BP (30% fresh matter basis), and LAB+BP. Silages were opened on days 3, 5, 7, 15, 30, and 60 of fermentation. The chemical composition, organic acid content, and in vitro ruminal digestion of the 60-day silage were determined. The pH of LAB-treated silage was lower than that of the silage without LAB. Furthermore, the LAB-treated silage...

Filamentous fungi associated with mosquito larvae (Diptera: Culicidae) in municipalities of the Brazilian Amazon Neotropical Entomology
Pereira,Eleny da S; Sarquis,Maria I de M; Ferreira-Keppler,Ruth Leila; Hamada,Neusa; Alencar,Yamile B.
Several species of the family Culicidae are important vectors of diseases in humans and other animals. Immature stages are filter-feeders of organic particulate matter and microorganisms. Studies on microbial diversity can contribute to the discovery of new substances that can be used in the pharmaceutical industry for food or for biological control. The aim of this study was to isolate and identify the fungi associated with Culicidae larvae found in different habitats (natural and artificial), such as fruit shells, rock holes, lakes, aquatic plants, palm bracts and ceramic pots, in several municipalities of Brazilian Amazonia, especially in the states of Amazonas and Rondônia. A total of 38 fungal lineages were isolated from larvae of Aedes aegypti (L.),...

Microbial biomass and activity in litter during the initial development of pure and mixed plantations of Eucalyptus grandis and Acacia mangium Rev. Bras. Ciênc. Solo
Bini,Daniel; Figueiredo,Aline Fernandes; Silva,Mylenne Cacciolari Pinheiro da; Vasconcellos,Rafael Leandro de Figueiredo; Cardoso,Elke Jurandy Bran Nogueira.
Studies on microbial activity and biomass in forestry plantations often overlook the role of litter, typically focusing instead on soil nutrient contents to explain plant and microorganism development. However, since the litter is a significant source of recycled nutrients that affect nutrient dynamics in the soil, litter composition may be more strongly correlated with forest growth and development than soil nutrient contents. This study aimed to test this hypothesis by examining correlations between soil C, N, and P; litter C, N, P, lignin content, and polyphenol content; and microbial biomass and activity in pure and mixed second-rotation plantations of Eucalyptus grandis and Acacia mangium before and after senescent leaf drop. The numbers of cultivable...

Microorganisms contaminated in the process of cultivation and their effect on the production of shiitake Taiwan Agricultural Research Institute
Ying-Ming Liao; 廖英明.
[[abstract]]Contamination has been a major problem for the shiitake production in Taiwan. To eliminate the contamination to a level as low as possible is very important. In this study, the contaminated microorganisms were identified and the sources of contaminants in the sawdust, spawn, inoculation and incubation rooms, and cultivation yard were described. Attempts were also made to explore the effects of the contaminants on the mycelial growth and/or the yield of shiitake. The effect of medium pH values on the mycelial growth of shiitake and contaminants were also reported. Results indicated that species of Trichoderma, Penicillium, Neurospora and Aspergillus were the most frequently isolated fungi from the sawdust spawn, while Trichoderma, Bacillus and...

Phosphate-solubilizing fungi isolated from a semiarid area cultivated with melon (Cucumis melo L. cv. gold mine) Acta Botanica
Coutinho,Flavia Paiva; Cavalcanti,Maria Auxiliadora de Queiroz; Yano-Melo,Adriana Mayumi.
Considering that little is known about the occurrence of phosphate-solubilizing fungi from areas cultivated with melon, the phosphate solubilization ability of filamentous fungi isolated in these areas was evaluated. Three hundred and eighteen filamentous fungal isolates belonging to 23 genera were evaluated, besides Aphyllophorales and Mycelia sterilia. From those, 52 were able to solubilize P: Aphyllophorales (2), Aspergillus (34), Penicillium (10) and Rhizopus (6). These results will contribute to subsidizing further research regarding the capacity of these fungi to solubilize other sources of phosphate applied to the melon crop, as well as indicate the need for a screening program to select those with higher capacity and potential for solubilization.

The wide spectra of colonizing microorganism, likewise Burkholderia pseudomallei, has been found in different habitats, and presenting distinct activity, as exerting physiological functions among plants, or as a pathogen for man, animals and also as a phytopathogen. A common disease of men and animals caused by B. pseudomallei, melioidosis, is a severe morbidity that usually culminates in the host death. Soil samples from different areas in the Amapá state, in northern Brazil, were screened for environmental microorganisms to assess potential antimicrobial activity aiming at biotechnological applications. Among the prospected microorganisms, B. pseudomallei was isolated from high humidity soils, mangrove, which is rich in organic materials, produced by the...
