«Estudio bacteriológico y diferencial de las distintas especies del género azotobacter»
Abstract
Se hace un estudio bacteriológico del género Azotobacter, dando a conocer nuevas técnicas de coloración y de diferenciación de especies. Se pone de manifiesto la existencia de formas ácido-alcohol resistentes. Las técnicas de concentración de colorantes, reducción e inhibición del crecimiento por el telurito potásico, así como la de inhibición por discos impregnados de colorantes, permiten diferenciar las especies del género Azotobacter de un modo seguro y rápido, llegando a la conclusión de que existen cuatro especies perfectamente individualizadas: Az. chroococcum, Az. beijerinckii, Az. vinelandii y Az. agile.
