Two-phase aqueous systems have replaced and simplified steps in extraction purification processes, especially for biocompounds. Thus, this study evaluated the liquid-liquid equilibrium behavior of Pluronic L64 + water sodium salts at pH 5.0, 7.5, 10.0. Sodium sulfate demonstrated greatest phase separation, followed by citrate tartrate. Higher values resulted larger biphasic regions. The polymer...

OBJECTIVE Despite the great number of substances produced by the skincare industry, very few of them seem to truly have an effect on the skin. Therefore, given the social implications surrounding physical appearance, the search for new bioactive compounds to prevent or attenuate skin ageing and enhance self-image is a priority of current research. In this context, being rich in valuable compoun...

In this study, 3 mm thick quince slices were dipped in bitter orange (BO), tangerine (Citrus deliciosa Mediterranean) (CDM), (O), reticulata Owari) (CRO), pomegranate (P) juices and a non-pre-treatment (control) dried at an air temperature of 70 °C velocity 1.5 m/s. According to the results pre-treatment trials, drying time was found be minimum 121 min 5 dipping reach safe moisture content 10% ...

Opuntia joconostle fruit is a rich source of biocompounds such as polyphenols including gallic, vanilic, 4-hidroxybenzoic, cafeic, and syringic acids, catechin, epicatechin, rutin, and vanillin, besides betalains. The objective of this research was to evaluate the effect of supplementation polyphenols-rich extracts from different parts of Opuntia joconostle against carbon tetrachloride-induced ...

Microbial biofilms produce electrochemical interactions with metal surfaces by following a wide variety of different electron exchange pathways. Reviewing the mechanisms identified in the biocorrosion of steels leads us to distinguish direct and indirect mechanisms for biofilm-catalysed cathodic reactions. Indirect mechanisms are due to the production of metal oxides or hydrogen peroxide (aerob...

A sequential multi-stage procedure was applied on the extraction of biocompounds from Spirulina platensis. The process consisted in three steps: 1) aqueous extraction, using conventional thermal (CE), ohmic heating (OH, 7 V/cm), enzymatic treatment (EAE, 0.8 mgLysozyme/mL), or both OH and EAE combined; 2) ethanolic extraction; 3) CHCl3/MeOH extraction. results evidenced that combined OH-EAE all...

Biomaterials are strategies that allow researchers to expand the investigative aspects and identify potential for composition of objectives clinical use. This study aims evaluate use biocompounds with antimicrobial action as an alternative in coating endotracheal tubes. The methodology used was a narrative review bibliography. To this end, northern question elaborated according PICo strategy. d...

As the periodic emission of light pulses by emitting diodes (LEDs) is known to stimulate growth or induce high value biocompounds in microalgae, this flashing regime was tested on and biochemical composition microalgae Nannochloropsis gaditana, Koliella antarctica Tetraselmis chui. At low frequencies (e.g., 5 50 Hz, Duty cycle = 0.05), a strain-dependent inhibition an accumulation protein, poly...

Biosynthesis of nanoparticles has arisen as a promising alternative to conventional synthetic methodologies owing to its eco-friendly advantages, and the involved bioprotocol still needs further clarification. This research, for the first time from the standpoint of statistics, confirmed an electrostatic force or ionic bond-based interaction between the chloroauric ions and the involved biocons...
