25. Pseudomonas SP. in uninspected raw goat’s milk in Rio de Janeiro, Brazil
Abstract Although quite controversial from the point of view of food safety, a considerable number of people across different age and socioeconomic groups consume raw goat’s milk. Even if refrigerated after milking, raw goat's milk may still be susceptible to the lipolytic and proteolytic actions of psychrotrophic microorganisms, such as Pseudomonas. In th

26. Effects of different legume green manures on tropical soil microbiology after corn harvest
ABSTRACT Legume green manure is a popular practice for sustainable agriculture in tropical environments. The use of grain, forage and purely green manure legumes in a subhumid tropical area in Northeast Brazil was investigated to determine the total C and N contents and estimate C-microbial biomass, soil basal respiration, microbial and metabolic quotients,

29. OTIMIZAÇÃO DO PROCESSO NÃO INVASIVO E NÃO DESTRUTIVO DE EXTRAÇÃO E ANÁLISE DE METABÓLITOS VOLÁTEIS DE MAMÃO PAPAIA POR SPME-GC-MS
The analysis of volatiles is an alternative in the routine of quality control of fruits, since the volatile metabolites can change in the presence of microorganisms. A well-established method for extracting volatiles is the solid phase microextraction (SPME). This work aims to define some parameters (fiber coating, conditioning time and fiber exposure time)
