Polymerization of lignosulfonates by the laccase-HBT (1-hydroxybenzotriazole) s...
Prasetyo, E. N.; Kudanga, T.; Østergaard, L.; Rencoret, J.; Gutiérrez, A.; Río, J. C. del; Santos, J. I.; Nieto, L.; Jiménez-Barbero, JesúsThe ability of laccases from Trametes villosa (TvL), Myceliophthora thermophila (MtL), Trametes hirsuta (ThL) and Bacillus subtilis (BsL) to improve the dispersion properties of calcium lignosulfonates 398 in the presence of HBT as a mediator was investigated. Size exclusion chromatography showed an extensive increase in molecular weight of the samples incubated with TvL and ThL by 107% and 572% from 28400 Da a...
Anatomical studies of sibling species within neotropical lymnaeids, snail inter...
Pointier,JP; Cazzaniga,NJ; González-Salas,C; Gutiérrez,A; Arenas,JA; Bargues,MD; Mas-Coma,SSeveral anatomical parameters of the reproductive system have been used to distinguish Lymnaea cubensis from L. viatrix, the snail hosts of fascioliasis in South America and the Caribbean area. Three samples have been collected in the type localities of L. cubensis (Cuba), L. viatrix var. A ventricosa (Argentina, Río Negro Lower Valley), and L. viatrix var. B elongata (Peru, Lima), respectively. Only one parame...
