Improvement in RNA extraction from S. cerevisie by optimization in the autolysis and NH3 hydrolysis
(Brazilian Archives of Biology and Technology, 2011-10-01)
The optimization of autolysis of Saccharomyces cerevisiae from brewery was studied aiming at the maximum ribonucleic acid extraction and yeast extract production. The best conditions for yeast autolysis was 55.2ºC, pH= 5.1 ...
Differential expression of plg genes from Penicillium griseoroseum: plg1 a pectinolytic gene is expressed in sucrose and yeast extract
(Journal of Applied Microbiology, 2017)
High pressure co2 extraction. Fundamentals and applications in the food industry
(SAGE PUBLICATIONS LTD, 1999)
Supercritical extraction (SFE) is a unit operation that exploits the dissolving power of supercritical fluids (SF) under conditions above their critical temperature and pressure. It is possible to obtain solvent-free ...
Supercritical CO2 extraction of Chilean hop (Humulus lupulus) ecotypes
(JOHN WILEY & SONS LTD, 2003)
Hops (Humulus lupulus L) have very stringent requirements of diurnal light hours during flowering. Thus, the beer industry is permanently assessing new agricultural land to grow hops, southern Chile being an excellent ...
The removal of dinitrochlorobenzene from industrial residuals by liquid-liquid extraction with chemical reaction
(Associação Brasileira de Engenharia Química, 2007-07)
Nitrochlorobenzenes (NCBs) are very important in the chemical industry since they have been used as raw material for the manufacture of crop protection products, as active ingredients in the pharmaceutical industry, as ...
Evaluation of enzymatic Pectin extraction by a recombinant Polygalacturonase (pgi) from apples and pears pomace of argentinean production and characterization of the extracted pectin
(OMICS Publishing Group, 2014-08)
Argentina produces, annually, 1.8 million tons of pome fruit, distributed almost equally between apple and pear. These fruits, produced in the High Valley of Río Negro are already a registered brand in the world of fruit. ...
Pressure drop may negatively impact supercritical CO2 extraction of citrus peel essential oils in an industrial-size extraction vessel
(2019)
We determined the effect of pressure drop (Delta P) in a 3.6-m tall vessel on the CO2 extraction of Citrus Peel Oil (CPO). We represented mass transfer using a linear-driving-force model and a pseudo-Sips' desorption ...
Mathematical modeling of vegetable oil-solvent extraction in a multistage horizontal extractor
(Elsevier, 2008-04)
A new mathematical model of vegetable oil extraction in an industrial De Smet type extractor is proposed. Solvent extraction from a mobile bed of oilseed material was modeled considering different availability of oil in ...
Comparision of conventional and supercritical co2-extracted rosehip oil
(BRAZILIAN SOC CHEMICAL ENG, 2000)
Supercritical CO2 (SCO2) can be utilized to extract oils from a number of plant materials as a nontoxic alternative to hexane, and there is industrial interest in using SCO2 extraction to obtain high-quality oils for ...
