Comparison of conventional and extractive fermentation using aqueous two-phase system to extract fibrinolytic proteases produced by Bacillus stearothermophilus DPUA 1729
(2020-01-01)
Fibrinolytic enzymes have been considered promising for treatment and protection of healthy circulation due its ability to dissolve the fibrin in blood clots. Extractive fermentation is a not explored and efficient downstream ...
Genotoxic potential of leaf extracts of Jatropha gossypiifolia L.
(Funpec-editora, 2016-01-01)
Jatropha gossypiifolia L. (Euphorbiaceae) is widely used in popular medicine. However, further toxicological studies are necessary for its reliable use. The present study aimed to evaluate the cytotoxic, genotoxic, and ...
Germination inhibitory activity of aqueous extracts of native grasses from South America
(Instituto de Pesquisas Jardim Botânico do Rio de Janeiro, 2021-01)
Soluble allelochemicals have generated great interest since they can be used for the biological control of pests, especially of weeds. However, few studies have evaluated the effectiveness of soluble compounds of exudates ...
Exploitation of a single interface flow system for on-line aqueous biphasic extraction
(ELSEVIER SCIENCE BV, 2010)
The exploitation of aqueous biphasic extraction is proposed for the first time in flow analysis This extraction strategy stands out for being environmentally attractive since it is based in the utilization of two immiscible ...

Aqueous two-phase systems
(2019-01-01)
During the last 60 years, aqueous two-phase systems (ATPS) have been the focus of much research. A large number of studies have been reported on the characterization of these systems and their use on separation, analytic, ...
4-amine-2-mercaptopyrimidine modified silica gel applied in Cd(II) and Pb(II) extraction from an aqueous medium
(Versita, 2010-01-01)
This paper discusses silica surface modification by a process involving a two-step reaction: anchoring of a silylating agent, followed by an attachment of a 4-amino-2-mercaptopyrimidine molecule. The modified material ...
