The objectives of this study were to evaluate the potential of gabiroba Campomanesia pubescens (DC) O. Berg in the production of a beverage fermented using selected and wild yeasts from indigenous fermentation, analyze the volatile compounds profile present during the process of fermentation, and evaluate the sensory quality of the final beverage produced.(More)
Spontaneous cocoa bean fermentations performed under bench- and pilot-scale conditions were studied using an integrated microbiological approach with culture-dependent and culture-independent techniques, as well as analyses of target metabolites from both cocoa pulp and cotyledons. Both fermentation ecosystems reached equilibrium through a two-phase(More)
Cauim is a fermented beverages prepared by Tapirapé Amerindians in Brazil from substrates such as cassava, rice, peanuts, pumpkin, cotton seed and maize. Here we study the microorganisms associated with peanut and rice fermentation using a combination of culture-dependent and -independent methods. The bacterial population varied from 7.4 to 8.4 log CFU/ml.(More)
This study used a multiphasic approach, characterized by the simultaneous use of culture-dependent and culture-independent methods, to investigate endophytic bacterial communities in strawberry (Fragaria ananassa) fruit. A total of 92 bacterial endophytes were isolated and initially grouped by their repetitive extragenic palindromic (rep)-PCR banding(More)
This work was aimed at isolating and identifying the microbiota present during the semi-dry method of coffee processing using polyphasic methods and to evaluate microbial diversity with PCR-DGGE. Samples of Coffea arabica L. were collected during different processing stages in southern Minas Gerais, Brazil. The bacterial and fungal isolates were(More)
BACKGROUND Synthetic skin analogues or living allogeneic or autologous cells are used as dressings for the care of skin wounds, as well as temporary or permanent substitutes for damaged epithelia. OBJECTIVES To evaluate if keratinocyte growth on a swine pericardium substrate mimics the natural epithelial layers compared with cultures on allogeneic dermis,(More)
This work's goal was to research new candidate antigens for cutaneous leishmaniosis (CL). In order to reach the goal, we used random peptide phage display libraries screened using antibodies from Leishmania braziliensis patients. After selection, three peptides (P1, P2, and P3) were synthesized using Fmoc chemistry. The peptides individually or a mixture of(More)
