13. Microcystin-XR degradation by bacteria isolated from public water supply system / Degradação da microcistina-XR por bactérias isoladas de sistema de abastecimento público de água
Microcystins are potent hepatotoxins and tumor promoters found in freshwaters that cause public health risks and thus represent a serious problem for water treatment plants. The cyanobacterium genus Microcystis is the most known toxin-producer and the most common bloom-forming in water reservoirs used for public supply. However, some bacteria are able to use

15. Variabilidade espacial de atritos físicos e químicos em solos de vale aluvial no semiárido de Pernambuco.
The study of soil hydraulic conductivity assumes high importance, being a parameter that measures the easiness which the soil‟s pores transmit water, being a relevant factor for the soil-water-plant system. Associated with this, another important parameter is the physical soil resistance to root penetration, which it has been the subject of extensive s

16. Tratamento com lodo aeróbio granular de efluente de fábrica de papel / Aerobic granular sludge treatment of paper mill effluents
The activated sludge process is widely used for the treatment of industrial effluents, achieving high rates of organic matter removal. Nevertheless, the separation of biological sludge in secondary clarifiers can be a serious problem of this process due to the poor floc formation, causing solids losses and, consequently, deterioration of treated effluent qua

17. Survival of pathogenic intestinal spirochetes kept in pure cultures and in pig feces held at four different temperatures.
A espiroquetose do cólon dos suínos (ECS), doença causada pela Brachyspira pilosicoli, tem sido identificada como uma causa de diarréia e queda de performance em suínos na fase de crescimento em todos os maiores países produtores do mundo. O conceito atual de que a transmissão da ECS ocorra através da contaminação ambiental por animais aguda ou per

20. Isolation and identification of Profenofos degrading bacteria
An enrichment culture technique was used to isolate bacterial strains responsible for the biodegradation of profenofos in a soil from Hubei province of central China. Two pure bacterial cultures, named W and Y, were isolated and subsequently characterized by sequencing of 16S rRNA genes and biochemical tests. Isolate W showed 96% similarity to the 16S rRNA g

21. Technological profile of bifidobacteria strains in pure culture and in co-culture with Streptococcus thermophilus in organic and conventional milks / Perfil tecnológico de cepas de bifidobactéria em cultura pura e em co-cultura com Streptococcus thermophilus em leites orgânico e convencional
The concern about sustainable technologies and demand for new functional foods arouses the interest for the development of new food products in addition to provide nutrition and health benefits to the consumer. Thus, this work aims to offer organic milk as a potential raw material for the manufacture of probiotic fermented milk. Therefore, studying the techn

24. Evaluation for leptospirosis vaccine. Relation between in vitro growh inibition test and potency test in hamsters / Avaliação de vacinas antileptospirose. Relação entre o teste de inibição de crescimento de leptospiras in vitro e o teste de desafio em hamsters
It was investigated the existence in hamsters of correlation between the standard potency test of bacterins antileptospires and the in vitro leptospires growth inhibition test. The assays were performed, in male hamsters, separately according to the commercial (A and B) animal antileptospirosis bacterin used. The quality of the bacterins and the level of neu
