This study aimed to identify lactic acid bacteria (LAB) in byproducts of fruit (Malpighia glabra L., Mangifera indica Annona muricata and Fragaria vesca L.) pulp processing. Fifty strains LAB were identified using matrix-assisted laser desorption/ionization-time flight mass spectrometry (MALDI-TOF MS) 16S rRNA gene sequence (16S rRNA) analysis. Species belonging Lactobacillus genus the predominant all processing byproducts. The average congruency between MALDI-TOF MS species identification...
Catabolism of amino acids via the Ehrlich pathway involves transamination to corresponding alpha-keto acids, followed by decarboxylation an aldehyde and then reduction alcohol. Alternatively, may be oxidized acid. This is functional in Saccharomyces cerevisiae, since during growth glucose-limited chemostat cultures with phenylalanine as sole nitrogen source, phenylethanol phenylacetate were produced quantities that accounted for all consumed. Our objective was identify structural gene(s)...
To identify and characterize the main contaminant yeast species detected in fuel-ethanol production plants Northeast region of Brazil by using molecular methods.Total DNA from colonies isolated fermentation must industrial alcohol was submitted to PCR fingerprinting, D1/D2 28S rDNA sequencing species-specific analysis. The most frequent non-Saccharomyces cerevisiae isolates were identified as belonging Dekkera bruxellensis, several genetic strains could be discriminated among isolates....
ABSTRACT Aerobic, glucose-limited chemostat cultures of Saccharomyces cerevisiae CEN.PK113-7D were grown with different nitrogen sources. Cultures phenylalanine, leucine, or methionine as a source contained high levels the corresponding fusel alcohols and organic acids, indicating activity Ehrlich pathway. Also, derived from other two amino acids detected in supernatant, suggesting involvement common enzyme activity. Transcript level analysis revealed that among five...
Abstract Background Bacteria may compete with yeast for nutrients during bioethanol production process, potentially causing economic losses. This is the first study aiming at quantification and identification of Lactic Acid (LAB) present in industrial processes different distilleries Brazil. Results A total 489 LAB isolates were obtained from four 2007 2008. The abundance fermentation tanks varied between 6.0 × 10 5 8.9 8 CFUs/mL. Crude sugar cane juice contained 7.4 7 to CFUs. Most belonged...
The non-invasive intracranial pressure (NIICP) method based on a skull deformation has been proven to be significant tool for an assessment of the (ICP) and compliance. Herein, we present development characterization novel wireless sensor that uses this as its working principle was designed easy use, have high resolution, achieve good accessibility. Initially, brief review physiology fundamentals ICP historic evolution NIICP are mentioned. architecture rationale chosen components then...
Cheese whey (CW) represents a potential substrate in biotechnological processes due to the presence of valuable nutrients its composition. Therefore, CW is used as low-cost fermentation for microbial growth and synthesis value-added compounds, while mitigating environmental impact that this by-product can cause. The current study aimed obtain exopolysaccharides (EPS) by fermenting lactic acid bacteria followed optimizing production using Response Surface Methodology (RSM) evaluating...
Botryosphaeria dieback is an important disease of table grape in the São Francisco Valley, main Brazilian exporting region. The objectives this study were to identify species Lasiodiplodia associated with botryosphaeria grapes investigate prevalence and distribution region, evaluate their pathogenicity virulence green shoots grape. A total 112 isolates obtained from 14 vineyards, located Casa Nova, Juazeiro Petrolina. Fungal identifications made using phylogenetic analysis based on partial...
ABSTRACT A wealth of biochemical and molecular data have been reported regarding ethanol toxicity in the yeast Saccharomyces cerevisiae . However, direct physical on effects stress cells are almost nonexistent. This lack information can now be addressed by using atomic force microscopy (AFM) technology. In this report, we show that stiffness glucose-grown challenged with 9% (vol/vol) for 5 h was dramatically reduced, as shown a 5-fold drop Young's modulus. Quite unexpectedly, mutant...

Dekkera bruxellensis has been described as the major contaminant yeast of industrial ethanol production, although little is known about its physiology. The aim this study was to investigate growth in diverse carbon sources and involved conducting shake-flask glucose- or sucrose-limited chemostats experiments, from chemostat data, stoichiometry biomass formation during aerobic established. As a result experiments with hexoses disaccharides, specific rates were calculated, different behavior...
