1. Conteúdo e bioconversão de isoflavonas β-glicosídeos em agliconas nas condições de processamento do tempeh de soja
Resumo: O objetivo deste trabalho foi avaliar o efeito das condições de processamento do tempeh de soja sobre o conteúdo de isoflavonas β-glicosídeos e sobre sua bioconversão em agliconas. Diferentes tempos de maceração (6, 12 e 18 horas), cozimento (15, 30 e 45 minutos) e fermentação (18, 24 e 30 horas) com Rhizopus oligosporus a 37°C foram avali

2. Tempeh flour as a substitute for soybean flour in coconut cookies
The objective of this study was to prepare roasted and lyophilized tempeh flour with soybean cultivar BRS 267 to apply them in the formulation of coconut biscuits. The cookies produced with whole soy flour and mixed flour of soybean and tempeh were evaluated for proximate composition, fatty acid profile, and isoflavone aglycones in order to verify the effect

3. Phenolic content, antioxidant activity and antiamylolytic activity of extracts obtained from bioprocessed pineapple and guava wastes
The relationship between phenolic content, antioxidant and antiamylolytic activities was investigated in Rhizopus oligosporus-mediated solid-state bioprocessing of pineapple and guava residues. Two different treatments of fruit residues mixed with soy flour (5g of soy flour and 5g of fruit residue; 1g of soy flour and 9g of fruit residue) were inoculated and

4. Mudanças no perfil de isoflavonas e na composição química de 'tempeh' durante o processamento e a refrigeração
O objetivo deste trabalho foi analisar mudanças no perfil de isoflavonas, determinado por meio de cromatografia líquida de alta eficiência, em diferentes estágios do processamento e após refrigeração de 'tempeh'. Para a produção do 'tempeh', grãos de soja limpos das cultivares BR 36 (baixo teor de isoflavonas) e IAS 5 (alto teor) foram descascados,

5. Biotransformation of sclareolide by filamentous fungi: cytotoxic evaluations of the derivatives
O esclareolido (1) foi incubado com oito diferentes espécies de fungos filamentosos usados convencionalmente para bio-oxidações. O composto 1 metabolizado pelo fungo Aspergilus niger em um meio de cultura A forneceu o 3-cetoesclareolido (2) e 3β-hidroxiesclareolido (4). Quando em um meio de cultura B (mais rico em nutrientes em relação ao meio de cultu

6. Production of extracellular lipases by Rhizopus oligosporus in a stirred fermentor
The present investigation deals with the kinetics of submerged extracellular lipases fermentation by both wild and mutant strains of Rhizopus oligosporus var. microsporus in a laboratory scale stirred fermentor. Other parameters studied were inoculum size, pH, agitation and rate of aeration. It was found that the growth and lipases production was increased g

7. Potential application of native lipases in the resolution of (RS) - phenylethylamine
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) bas

8. Funcionalidade dos extratos fenólicos obtidos pelo cultivo semi-sólido de resíduos de abacaxi (Ananas comusus L.) e goiaba (Psidium guajava L.)
Solid substrate cultivation (SSC) has become an efficient alternative towards rational use of agro industrial wastes and production of value-added products, mainly in developing countries. This work presents the production and functional application results of phenolic extracts obtained by solid substrate cultivation of pineapple (Ananas comosus L.) and guav

9. Rice-Grown Rhizopus oligosporus Inoculum for Tempeh Fermentation
A method of growing Rhizopus oligosporus on cooked rice as the inoculum for the fermentation of soybeans into tempeh was described and evaluated. Isolated R. oligosporus spores on glass beads survived best at low temperature and intermediate humidity. The activity of the rice-grown inoculum to ferment soybeans into tempeh did not decrease appreciably when st

10. Penetration of Rhizopus oligosporus into Soybeans in Tempeh
Histological observations were made on the penetration of hyphae of Rhizopus oligosporus into soybean cotyledons in tempeh, an Indonesian soybean food. Hyphal penetrations averaged one per 1,400 μm2 (±390 μm2) on the curved (outer) cotyledon surface and one per 1,010 μm2 (±340 μm2) on the flat (inner) one. Hyphae infiltrated to a depth of 742 μm, or a

11. Factors affecting production of mold mycelium and protein in synthetic media.
The effects of certain cultural conditions on the yield of dry mycelium, protein, and total amino acid content of Rhizopus oligosporus Saito (NRRL 2710), Rhizopus rhizopodiformis (Cohn apud Lichtheim) Zopf (NRRL 6246), and Absidia corymbifera (Cohn) Sacc. et Trotter (NRRL 6247) were studied. The yield of mycelium was found to significantly increase as the sp

12. Germination of Rhizopus oligosporus Sporangiospores
The morphology of Rhizopus oligosporus (NRRL 2710) sporangiospores and their physiological requirements for germination were studied. Germination proceeded in two separable phases: phase I (swelling) and phase II (germ tube protrusion). The optimal conditions for germination were 42°C and pH 4.0. Sporangiospores contained insufficient endogenous carbon for
