| This review covers the history on Biological Nitrogen Fixation (BNF) in Graminaceous plants grown in Brazil, and describes research progress made over the last 40 years, most of whichwas coordinated by Johanna Döbereiner. One notable accomplishment during this period was the discovery of several nitrogen-fixing bacteria such as the rhizospheric (Beijerinckia fluminensis and Azotobacter paspali), associative (Azospirillum lipoferum, A. brasilense, A. amazonense) and the endophytic (Herbaspirillum seropedicae, H. rubrisubalbicans, Gluconacetobacter diazotrophicus, Burkholderia brasilensis and B. tropica). The role of these diazotrophs in association with grasses, mainly with cereal plants, has been studied and a lot of progress has been achieved in the... |

| AbstractMaize is considered a source of carotenoids; however, these compounds are highly unstable, degraded by high temperatures, exposure to light and presence of oxygen. The objective of this work was to evaluate the influence of the moisture and type of drying applied to grains on the level of carotenoids in yellow maize. The experiment was conducted in a completely randomized design (2 × 4 factorial), two levels of initial moisture at the harvest (22 and 19%) and three types of drying (in the sun; in the shade and in a dryer) and control (no drying). The samples of grains after drying with 12% of final moisture were analyzed by concentration of total carotenoids, carotenes (α-carotene + β-carotene), monohydroxilated carotenoids (β-cryptoxanthin), and... |

| Abstract The cereal bars are products globally accepted and consumed by all age groups. In this study, by Response Surface Methodology (RSM), the effects of different concentrations of inulin, acacia gum and sorbitol in the characteristics of hardness, color and water activity of cereal bars were studied. A total of 17 experiments being 8 factorials, 6 axials and 3 repetitions at the central point were performed. The regression model presented for the hardness was significant indicating that the quantities of inulin, acacia gum and sorbitol affect the hardness of the cereal bars. Referring to color it was observed that the less inulin and more sorbitol, the more yellow the tone of the bars was. The results of water activity were not influenced by the... |

| Based on morphology and DNA sequence data the taxonomic relationships of Microdochium, Monographella and Idriella were reassessed. Microdochium is morphologically and phylogenetically circumscribed, and the sexual genus Monographella treated as synonym on the basis that Microdochium has more species, is more commonly encountered, and more frequently used in literature. An epitype is designated for Microdochium phragmites, and several well-known species are redefined based on their morphology and DNA sequence data (LSU, ITS, BTUB and RPB2). Furthermore, the revision of Microdochium led to six new combinations (M. albescens, M. consociatum, M. fusariisporum, M. maydis, M. opuntiae and M. stevensonii) and six new species (M. citrinidiscum, M. colombiense, M.... |
