A biodiversidade esteve e está em constante transformação natural, mas devido às ações exercidas pelo homem, seja pela extração de recursos naturais consequentemente a geração poluição descarte inadequado dos resíduos, acelerou extinção espécies matérias-primas aplicadas no processo produção. Nesse cenário, para produção novos produtos necessitou da física química resíduos e, portanto, adoção tecnologias específicas o tratamento disposição final ambientalmente correta. Todavia, nem todos os...
Microalgae are aquatic unicellular microorganisms that can be found both in freshwater and marine systems; capable of photosynthesis; grow as individual cells or associated chains small colonies. cultivation has gained large momentum among researchers the past decades due to their ability produce value metabolites, remarkable photosynthetic efficiency, versatile nature. The wide technological potential, thus increasing amount scattered knowledge, may become very first barrier a post...
The concentration of pineapple juice is needed to retain the bromelain activity and standardize composition proteolytic activity. Thus, this work aimed obtain a pure extract from Ananas comosus L. Merril by membrane separation process. A 2² experimental planning was used study influence pH transmembrane pressure on recovery micro-filtration using plain membrane. In second step, enzyme purified ultra-filtration 10 kDa millipore kit. best operation condition at 7.5 0.05 bar, while 85%...
The biosurfactant production is characterized by high costs with substrates, which does not make them sufficiently competitive against synthetic surfactants. insertion of alternative sources low cost, especially agro-industrial residue, an excellent to this competitiveness viable. An alkaline pretreatment was used extract the hemicellulose from corncob in order enhance its C5 fraction, common vegetable biomasses. hemicellulosic liquor glucose and mineral salt solution as carbon nutrients a...
In this work the α and β-amylase enzymes were obtained from maize (Zea mays) malt biochemistry characterized. A germination study to obtain with good amylase activity was made. The seeds germinated in laboratory enzymatic measured daily. Activity dependence time fitted an exponential model (A=A0eµt), which showed that behaviour of process similar growth microorganism. Its could be applied describe mechanism α-amylase production for each varieties others cereals. Maize characterization had...
Herein, the biosorption of Cr(VI) by magnetized coconut fibres obtained from agricultural waste has been described. Magnetization was achieved incorporating magnetite nanoparticles into a coprecipitation reaction in alkaline media. The capacity evaluated two series experiments. In first series, 500 mg L−1 biosorbent added to 50 K2Cr2O7 solution at 28 °C and stirred 200 rpm pH varied 1 13 determine optimum value. second experiments sorption pH, under same agitation speed temperature but with...
Microalgae have a high growth rate, CO2 absorption capacity, and content of chlorophyll, proteins, vitamins, mineral salts, carbohydrates, antioxidant substances, fatty acids. In recent years, Chlorella vulgaris has been widely used as feedstock for producing third-generation biofuels, such bioethanol. Thus, this work aims to develop strategy increase the production scale microalgae grown in distilled reused water, supplemented with modified BG-11 medium, use biomass The total cultivation 72...
This work aimed to study the drying process optimization of maize (Zea Mays) malt for obtaining malt, without affecting enzymatic activity alpha e beta-amylases from malt. Results showed that dryer operation must occur in zone at 54°C and 5.18-6 h time. The obtained had good properties.
This work aimed to establish the relationship between compositions and pH of ATPS PEG 6000/CaCl2 proteins partition from maize malt also simplify process optimization in for a statistical model, established by response surface methodology (RSM). Results showed that these were no influence on phase diagrams composition tie line length ATPS. SRM analyses elevated larger best conditions recovering proteins. The maximum coefficient was about 4.2 achieved single purification step. theoretical...
This work aimed to study the pH and transmembrane pressure effects during recovery of alpha beta amylases enzymes from corn malt (Zea mays) by hollow fiber membrane. The optimal condition was obtained for a statistical model, established response surface methodology (RSM). analysis showed that best operation amylolitics membrane 0.05 bar 5.00, while were purified about 26 times.
A moving bed bioreactor containing cubes of polyether foam immersed in a synthetic wastewater (an aqueous mixture meat extract, yeast dextrose, peptone, ammonium chloride, potassium sodium bicarbonate, mono-hydrogen-phosphate and magnesium sulphate) was used to evaluate bacterial growth biomass yield parameters based on Monod's equation. The supplied the bottom equipment flowing ascending parallel with diffused air current that provided mixing reactor content. Suspended attached...
In this study, seven wine samples were prepared varying the amount of pulp acerola fruits and sugar content using simulated annealing technique to obtain optimal sensory qualities cost for produced. S. cerevisiae yeast was used in fermentation process attributes evaluated a hedonic scale. Acerola wines classified as sweet, with 11°GL alcohol concentration aroma, taste, color characteristics fruit. The experiments showed that best conditions found at mass ratio between 1/7.5-1/6 total soluble...
The demand for bromelian and pineapple fruit has been increasing substantially in the world because of their benefits human health use diverse areas. In this context, work aimed to study capacity higher retention (concentration); bromelain activity underwent ultrafiltration from juice (Ananas comusus L. Merrill). All assays were carried out at pH 7.0 7.5, 0.05 0.40 bar transmembrane pressures. Results have shown that best operating conditions, between 85 87% was recovered using plain...
ABSTRACT This paper presents an approach of artificial neural networks to predict the sensorial qualities wines. A Kohonen network has been used as a software tool in order increase human skills this kind application. An initial prototype was implemented using technology, together with Visual Basic from Microsoft, for evaluation seven samples Barbados cherry ( Malpighia glabra L.) wine. Fifty consumers chosen, perhaps, had obtain data hedonic scale 1–9 times. Sensorial values flavor, aroma...
