Bradyrhizobium neotropicale sp. nov., isolated from effective nodules of Centrolobium paraense

Root nodule bacteria were isolated from Centrolobium paraense Tul. grown in soils from the Amazon region, State of Roraima (Brazil). 16S rRNA gene sequence analysis of seven strains (BR 10247(T), BR 10296, BR 10297, BR 10298, BR 10299, BR 10300 and BR 10301) placed them in the genus Bradyrhizobium with the closest neighbours being the type strains of Bradyrhizobium paxllaeri (98.8 % similarity), Bradyrhizobium icense (98.8 %), Bradyrhizobium lablabi (98.7 %), Bradyrhizobium jicamae (98.6 %), Bradyrhizobium elkanii (98.6 %), Bradyrhizobium pachyrhizi (98.6%) and Bradyrhizobium retamae (98.3 %). This high similarity, however, was not confirmed by the intergenic transcribed spacer (ITS) 16S-23S rRNA region sequence analysis nor by multi-locus sequence analysis. Phylogenetic analyses of five housekeeping genes (dnaK, gin/I, gyrB, recA and rpoB) revealed Bradyrhizobium iriomotense EKO5(T) (=LMG 24129(T)) to. be the most closely related type strain (95.7% sequence similarity or less). Chemotaxonomic data, including fatty acid profiles [major components being C-16:0 and summed feature 8 (18:1 omega 6c/18:1 omega 7c)] DNA G+C content, slow growth rate and carbon compound utilization patterns, supported the placement of the novel strains in the genus Bradyrhizobium. Results of DNA-DNA relatedness studies and physiological data (especially carbon source utilization) differentiated the strains from the closest recognized species of the genus Bradyrhizobium. Symbiosis-related genes for nodulation (nodC) and nitrogen fixation (nil/-I) placed the novel species in a new branch within the genus Bradyrhizobium. Based on the current data, these seven strains represent a novel species for which the name Bradyrhizobium neotropicale sp. nov. is proposed. The type strain is BR 10247(T) (=HAMBI 3599(T))

Igreja Católica e mercados: a ambivalência entre a solidariedade e a competição

A Igreja Católica enfrenta, de forma ambígua, as vicissitudes dos mercados, o religioso e o econômico propriamente dito. Na década de 90, isso se tornou evidente por causa de dois movimentos opostos. De um lado, a Renovação Carismática - resposta católica à concorrência pentecostal no mercado religioso - fomentou o uso de técnicas de marketing e a projeção de padres cantores na grande mídia. De outro, a Teologia da Libertação, corrente politizada de esquerda que desencadeou, entre outras coisas, o engajamento em atividades associativas de produção econômica em um conjunto chamado economia solidária, apontado como resposta à "exclusão do mercado de trabalho" ou ao desemprego. O artigo contextualiza a relação do catolicismo com esses mercados na sociedade brasileira.<br>The Catholic Church faces in an ambiguous way the market's setbacks, the religious one and the economic itself. In the 1990s, it became obvious because of two opposites movements. On the one hand, the Charismatic Renewal, catholic reply to the Pentecostal (Pentecostal) competition at the religious market, has stimulated the use of marketing techniques and the projection of singer priests at the big media. On the other hand, the Liberation Theology, progressist tendency that has generated, among other things, the participation of militants in associatives economic enterprises, that belong to a set named solidary economy, which has been spread as a reply to "the labour market exclusion", that is, the unemployment. This article deals with the catholic relationship with those markets at the Brazilian society
