Chemical pre-treatment with NaOH, NaClO2 or peracetic acid of wheat straw, bagasse, corn cobs and groundnut shells increased cellulose utilization, cellulase activity and protein content ofAspergillus niger AS-101 used as a test biodegradative microorganism.


Le prétraitement chimique par NaOH, NaClO2 ou par l'acide peracétique de la paille de froment, de la bagasse, des épis de maïs ou des coquilles d'arachide, augmente l'utilisation de la cellulose, l'activité de la cellulase et le contenu en protéines d'Aspergillus niger AS-101, utilisé comme souche test dans la biodégradation par les microorganismes.


El pre-tratamiento químico con NaOH, NaClO2 o àcido peracético de paja de trigo, bagazo, mazorcas de maíz y cáscaras de cacahuete, incrementó la utilización de celulosa, la actividad celulásica y el contenido en proteínas deAspergillus niger AS-101.
