Performance and Economic Viability of Broiler Chickens Fed with Probiotic and Organic Acids in an Attempt to Replace Growth-Promoting Antibiotics
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2019-01-01)
The aim of this study was to evaluate diets supplemented with probiotic (Bacillus amyloliquefaciens) and organic acids (lactic, acetic and butyric acid) in attempt to replace the antibiotics and anticoccidial (avilamycin ...
Acetylation of bacterial cellulose catalyzed by citric acid: Use of reaction conditions for tailoring the esterification extent
(Elsevier, 2016-11)
Bacterial cellulose (BC) nanoribbons were partially acetylated by a simple direct solvent-free route catalyzed by citric acid. The assay of reaction conditions within chosen intervals (i.e. esterification time (0.5–7 h), ...
Use of Aspergillus niger in the bioleaching of colemanite for the production of boric acid

On the Optimization of Hydrolysis Conditions for Simultaneous Determination of Amino Acids and Amino Sugars in Marine Sediments
(SciTecnhol, 2013-07-18)
In the present work different approaches were tested for the optimization of the hydrolysis conditions for the joint determination of amino acids and amino sugars in chitin, an important structural polymer in fungi, ...
Studies for the transformation of carbocycles into carbohydrates: approach toward the synthesis of higher sugar derivatives
(Elsevier Sci LtdOxfordInglaterra, 2004)
Kinetics of autocatalytic acid hydrolysis of cellulose with crystalline and amorphous fractions
(SPRINGER, 2010)
The acid hydrolysis of cellulose with crystalline and amorphous fractions is analyzed on the basis of autocatalytic model with a positive feedback of acid production from the degraded biopolymer. In the condition of low ...
Radionuclide concentrations in raw and purified phosphoric acids from Brazil and their processing wastes: implications for radiation exposures
(Springer, 2012-02-01)
Radionuclides from the U and Th natural series are present in alkaline rocks, which are used as feedstock in Brazil for the production of raw phosphoric acid, which can be considered as a NORM (naturally occurring radioactive ...
Optimization of acid hydrolysis from the hemicellulosic fraction of Eucalyptus grandis residue using response surface methodology
(Elsevier B.V., 2007-01-01)
Biotechnological conversion of biomass into fuels and chemicals requires hydrolysis of the polysaccharide fraction into monomeric sugars. Hydrolysis can be performed enzymatically and with dilute or concentrate mineral ...
Influence of the combination of probiotic cultures during fermentation and storage of fermented milk
(Elsevier B.V., 2014-05-01)
The objective of this study was to evaluate the influence of different combinations of cultures, Lactobacillus acidophilus La and Bifidobacterium animalis subsp. lactis-Bb as pure cultures or in co-culture with Streptococcus ...
