O objetivo deste trabalho foi avaliar o potencial do uso de indutores de resistência bióticos e abióticos na redução da podridão radicular em mamoeiro. Mudas de mamoeiro foram pulverizadas com os fungicidas fosetil-Al, metalaxil e Mancozeb (2 g L-1), com os indutores abióticos fosfito de potássio (2,5 e 5 mL L-1), ácido salicílico 0,15 e 0,30%, Reforce (indutor comercial) + ácido salicílico a 5%, acibenzolar-S-metil (ASM) (0,15 e 0,30 g L-1), e com o indutor biótico Saccharomyces cerevisiae (3 e 6 mL L-1), três e seis dias antes da pulverização de 1 mL de suspensão de 10(5) zoósporos mL-1 de Phytophthora palmivora. Todos os tratamentos tiveram efeito no controle da podridão de raízes em relação à testemunha, com exceção do Reforce + ácido salicílico a 5%... |

ABSTRACT The aim of this study was to verify the effect of the addition of an enzyme complex on performance (feed intake, egg production, egg weight and egg mass, feed conversion per egg mass, and feed conversion per dozen eggs), and on egg quality (% of shell, albumen and yolk, shell thickness, specific gravity, Haugh unit, yolk index, and albumen index), in medium-heavy laying hens at 28 to 40 weeks of age. A total of 240 Hy-Line Brown laying hens were used in a randomised block design with 10 replications of six birds per lot and four treatments: positive control (basal feed), negative control (with a reduction in metabolisable energy, crude protein, calcium and phosphorus), negative control + enzymes, and positive control + enzymes. The enzyme complex,... |

The enzyme glucanase from Moniliophthora perniciosa was produced in liquid medium and purified from the culture supernatant. A multivariate statistical approach (Response Surface Methodology - RSM) was employed to evaluate the effect of variables, including inducer (yeast extract) and fermentation time, on secreted glucanase activities M. perniciosa detected in the culture medium. The crude enzyme present in the supernatant was purified in two steps: precipitation with ammonium sulfate (70%) and gel filtration chromatography on Sephacryl S-200. The best inducer and fermentation time for glucanase activities were 5.9 g L-1 and 13 days, respectively. The results revealed three different isoforms (GLUI, GLUII and GLUIII) with purification factors of 4.33,... |
