Two new eremophilane sesquiterpenes, cupressolide A and cupressolide B, along with two known sesquiterpenes, has been characterized from the EtOAc extract of a liquid medium where a

In this paper the electrochemical behavior of adrenaline was investigated on biosensors containing the enzyme laccase from Aspergillus oryzae using ILs (BMI • Tf.. 2 N or

The composition of the essential oil of Eugenia dysenterica collected from wild populations in Senador Canedo (SC) and Campo Alegre de Goiás (CA), as well as from

This result might also indicate that both series of compounds have higher antioxidant action in a mechanism different of electron scavenging. For the two methods tested, an

A miniaturized enzymatic assay using luorescent probes to reveal esterase producing microorganisms was optimized and applied to screen 64 soil bacterial strains.. The

Results suggest that in acid pH weak electrostatic interactions and hydrogen bonding are responsible for aggregates formation while in alkaline pH electrostatic interactions

where F o is DPH luorescence intensity in organic solvent, F is observed luorescence intensity, K SV is Stern-Volmer quenching constant and [H 2 O] is water molar concentration.

The results here presented support a random order kinetic mechanism of addition of substrates, and indicate that DD-CoA binding to free WT InhA follows the sequential model,
