Concentrado proteico de arroz na alimentação do jundiá (Rhamdia quelen)

O objetivo do presente trabalho foi avaliar a inclusão do concentrado proteico da destilação de etanol obtido de arroz (CPA) na alimentação do jundiá. Trezentos e setenta e cinco peixes foram distribuídos em sistema de recirculação de água com 15 caixas (125L). Foram testadas três dietas (37% ...

The influence of new heat–treated NiTi alloy on shaping ability and apical transportation of maxillary molars. The evaluation of the larger apical preparation on mesiobuccal and distobuccal canals of maxillary molars: a micro-computed study

The aim of this study was to evaluate canal transportation; centering ability; dentin thickness; change in volume, and time spent on shaping ability of maxillary molars prepared with mechanized NiTi file systems composed of a conventional NiTi alloy (Mtwo), a CM-Wire (Prodesign R and Hyflex CM) NiTi allo...

Effect of Myracrodruon urundeuva and Qualea grandiflora extracts on viability and activity of microcosm biofilm and prevention of enamel demineralization in vitro

The objective of this study was to evaluate the antimicrobial and anti-caries effects of two plant extracts. The first chapter dealt with a review of the literature whose objective was to discuss the antimicrobial potential of Brazilian natural agents on the biofilm related to dental caries and gingiviti...

Polifenóis não-extraíveis provenientes do guaraná (Paullinia cupana): caracterização por MALDi-TOF/TOF e avaliação do potencial e cinética de inibição da alfa-glicosidase

Introdução: Polifenóis não-extraíveis (NEPPs) são uma fração de polifenóis que não são extraídos da forma convencional por estarem associados à parede celular de produtos de origem vegetal. Um corpo crescente de estudos tem evidenciado seus potenciais efeitos benéficos, especialmente associ...

First report of the production of a potent biosurfactant with α, β-trehalose by Fusarium fujikuroi under optimized conditions of submerged fermentation

Braz. j. microbiol; 49 (supl.1), 2018
Abstract Biosurfactants have many advantages over synthetic surfactants but have higher production costs. Identifying microorganisms with high production capacities for these molecules and optimizing their growth conditions can reduce cost. The present work aimed to isolate and identify a fungus with hig...

Bioconversion of waste cooking oil glycerol from cabbage extract to lactic acid by Rhizopus microsporus

Braz. j. microbiol; 49 (supl.1), 2018
Abstract Glycerol from spent oil was processed by transesterification for biodiesel production. Although glycerol contains many types of impurities, it can be used as a C-source for lactic acid production by fungi, such as Rhizopus microsporus. In this study, we found that wild type R. microsporus (LTH23...

Evaluation of skimmed milk flocculation method for virus recovery from tomatoes

Braz. j. microbiol; 49 (supl.1), 2018
Abstract This study aimed to evaluate the elution-concentration methodology based on skimmed milk flocculation from three varieties of tomatoes (Solanum lycopersicum L. [globe], Solanum lycopersicum var. cerasiforme [cherry] and hybrid cocktail [grape tomato]) for further monitoring of field samples. Spi...

Comparative proteomic analyses of Hyphozyma roseonigra ATCC 20624 in response to sclareol

Braz. j. microbiol; 49 (supl.1), 2018
Abstract Sclareol is an important intermediate for ambroxide synthesis industries. Hyphozyma roseonigra ATCC 20624 was the only reported strain capable of degrading sclareol to the main product of sclareol glycol, which is the precursor of ambroxide. To date, knowledge is lacking about the effects of scl...

The use of Prevotella bryantii 3C5 for modulation of the ruminal environment in an ovine model

Braz. j. microbiol; 49 (supl.1), 2018
Abstract In the Southern Hemisphere, ruminants are mostly raised in grazing systems where animals consume forage and are supplemented with low amounts of concentrates. Concentrates are usually given separately and are rapidly ingested. This practice leads to changing rumen environment conditions during t...

Antimicrobial potential of pyroligneous extracts - a systematic review and technological prospecting

Braz. j. microbiol; 49 (supl.1), 2018
Abstract Pyroligneous extract is applied in diverse areas as an antioxidant, an antimicrobial, and an anti-inflammatory agent. The discovery of new cost-effective antimicrobial agents of natural origin remains a challenge for the scientific community. This study aimed to conduct a systematic review and a...
