Casi tres décadas después se ha confirmado que el eminente cientista tenía razón, después de que las técnicas analíticas hayan mejorado significativamente y se hayan introducido en los laboratorios de limnología. El papel de la fosfatasa soluble en aguas dulces puede ser investigado en estrecha relación con el plancton productor o sencillamente en relación con otras entidades químicas que abundan en el agua de los lagos, con capacidad para condicionar la actividad de enzimas. Es el caso de las sustancias húmicas que forman complejos con fosfatasa soluble; la actividad enzimática será desactivada cuando hace parte del complejo (ligado a la molécula húmica) y reactivada de nuevo cuando el complejo es roto, por ejemplo por la radiación UV solar.Universidade de Lisboa.
