A mathematical model is developed for converting between the two measurement bases commonly used in the construction of growth profiles in solid-state fermentation, namely absolute mass ratio m(dry biomass)/m(initial dry matter) and relative mass ratio m(dry biomass)/m(dry matter). These are not equivalent, due to the loss of dry matter as CO2 during the fermentation. The model is equally appli...

O desempenho de duas lipases nativas (lipase de Aspergillus niger e Rhizopus oligosporus), e a influência da temperatura, doador acila (acetato de etila, acetato de vinila, acetato de iso-propenila e anidrido acético) e do meio orgânico foi avaliado na resolução da (RS)-feniletilamina (1). O efeito de anions em uma série de líquidos iônicos (LIs) baseados em derivados do imidazol [BMIm][X], ond...

Abstract Biofoam is a replacement packaging for Styrofoam made from natural fibres that are naturally biodegradable and food-safe. Many studies use chemicals starch as matrix adhesive in the manufacture of biofoam. In previous studies, biofoam cups have been developed using mold Rhizopus oligosporus which found coconut fibre. The objective this study was to analyse physical, thermal functional ...
