Zoothentic evaluation of tilapian alevines feed fed with kefir

Abstract: Introdução: Os probióticos possuem composição microbiológica variável, o que resulta em perfis de subprodutos distintos e conseqüente ação probiótica benéfica para os animais. Objetivo: caracterizar os microrganismos presentes em amostras de kefir e aqueles estabilizados em rações comerciais para consumo em piscicultura e avaliar o resultado em um perfil zootécnico. Metodologia: O processo de quantificação microbiana do kefir cultivado em leite, açúcar mascavo e ração misturado com grãos e soluções fermentadas… Show more

“…A total of 1 µL of the supernatant was applied to the 96-well MALDI-TOF MS target plate (Bruker Flex Control 3.4, Bruker Daltonics Inc., Billerica, MA, USA), in triplicate, and allowed to dry in the environment. The sample was covered with 1 µL of the matrix (saturated solution of α-cyano-4-hydroxy-cinnamic acid (Sigma, St. Louis, MO, USA) in 50% acetonitrile (Sigma, St. Louis, MO, USA) and 2.5% trifluoroacetic acid (Merck, Düren, Germany)), and after drying, the plate was inserted into the equipment (MALDI-TOF MS) to obtain the spectra (sequence of peaks) [38].…”
