Combinando workflows e semântica para facilitar o reuso de software

Este artigo apresenta um ambiente para o desenvolvimento de software baseado no reuso de componentes, que combina tecnologias de gerenciamento de workflows, semântica e componentes de software. O ambiente desenvolvido pode ser utilizado por desenvolvedores de software, projetistas de workflows e usuários finais. Um estudo de caso real é apresentado para demonstrar a utilização do ambiente.This paper presents an environment for component-based software development, which combines workflow management, semantics and software components technologies. The resulting environment can be used by different sorts of users: software developers, software designers, and end users. One real study case is presented to demonstrate the use of the environment.FAPESP 2009/10413-5FAPESP 2011/07968-5CNPq 304937/2010-0Pró-Reitoria de Graduação da Universidade de São Paul

Metagenomic analysis of a tropical composting operation at the São Paulo Zoo Park reveals diversity of biomass degradation functions and organisms.

Composting operations are a rich source for prospection of biomass degradation enzymes. We have analyzed the microbiomes of two composting samples collected in a facility inside the Sao Paulo Zoo Park, in Brazil. All organic waste produced in the park is processed in this facility, at a rate of four tons/day. Total DNA was extracted and sequenced with Roche/454 technology, generating about 3 million reads per sample. To our knowledge this work is the first report of a composting whole-microbial community using high-throughput sequencing and analysis. The phylogenetic profiles of the two microbiomes analyzed are quite different, with a clear dominance of members of the Lactobacillus genus in one of them. We found a general agreement of the distribution of functional categories in the Zoo compost metagenomes compared with seven selected public metagenomes of biomass deconstruction environments, indicating the potential for different bacterial communities to provide alternative mechanisms for the same functional purposes. Our results indicate that biomass degradation in this composting process, including deconstruction of recalcitrant lignocellulose, is fully performed by bacterial enzymes, most likely by members of the Clostridiales and Actinomycetales orders.FAPESP 2009/52030-5RCNPqCAPE
