| A produção brasileira de pinha (Annona squamosa L.) predomina no Nordeste, sendo afetada pela antracnose causada por Colletotrichum gloeosporioides. Este estudo avaliou: 1) as taxas de crescimento micelial e conidiação, dimensões de conídios e produção de amilase, xilanase, pectinases e protease por isolado desse fungo de lesões de abacate (Persea americana Mill), em diferentes meios; 2) as porcentagens de germinação e formação de apressórios do mesmo sobre folhas jovens de pinha; 3) as alterações in vivo nos teores de proteínas, fenóis e carboidratos solúveis totais, antes e após a inoculação. Folhas jovens de plântulas de dois ecótipos de pinha (PI e CT) foram destacadas, submetidas à inoculação e incubadas ou para sua extração (0 e 36 horas após), ou... |

| Abstract Biosurfactants possess diverse chemical properties and provide important characteristics to the producing microorganisms, which can act as surface-actives and emulsifiers of hydrocarbon and others water insoluble substances. Most of them are lipopeptides synthetized by Bacillus. This study evaluated the biosurfactant production by strains of Bacillus previously obtained from liquid residues of sugar-alcohol industry. The bacterial isolates LBPMA: BSC, BSD, J1, J2 and L1 were cultivated in medium that induces production of biosurfactants (Landy medium). During 48 h of incubation, at intervals of 12 h, the total contents of proteins, reducing carbohydrates and surfactant activity of the filtrated growth media free of cells were evaluated. The... |

| ABSTRACT Bee pollen results from the mixture of pollen and floral nectar with the salivary substances of bees and has increasingly been used as a food with therapeutic properties. In this study, 30 samples of bee pollen from Apis mellifera apiaries in three mesoregions of Alagoas (Brazil) - Mata Atlântica, South Coast and Caatinga, were collected during the dry season of 2008/09 and analysed. Mata Atlântica and Caatinga had good production of bee pollen. In the same season, Mata Atlântica contained a higher diversity of pollen types for feeding bees with a predominance of herbaceous pollen (63%), whereas the Caatinga samples contained monofloral pollen. Physicochemical data were analysed with the nonparametric Kruskal-Wallis statistical test. The Caatinga... |
