Microorganisms can produce lipases with different biochemical characteristics making necessary the screening of new lipase-producing strains for different industrial applications. In this study, 90 microbial strains were screened as potential lipase producers using a sensitive agar plate method with a suitable medium supplemented with Tween 20 and also a(More)
Cedecea lapagei is a gram-negative, facultative anaerobic, non-spore-forming bacteria, belonging to the family Enterobacteriaceae. It has been reported as a pathogen in few cases of bacterial peritonitis, wound infection, chemicals burns and pneumonia. We report a case of traumatic wound infection by this pathogen with a pertinent review.
The aim of this study was to evaluate changes in fatty acids composition, following the production of gamma-linolenic acid and the reduction of lipid concentration after agro-industrial substrates fermentation. A Mucor circinelloides strains was selected among seven fungal strains as the most effective gamma-linolenic acid producer in submerged cultivation.(More)
Background Despite 20 years of effort, the design of an effective HIV-1 vaccine remains an enormous challenge. In this scenario, new immunological approaches must be considered. Dendritic cells-based vaccines have been widely used in cancer therapy showing interesting successful results. More recently, Lu et al. (2004) described large reductions on virus(More)
