Biotransformation of indigo carmine to isatin sulfonic acid by lyophilized mycelia from Trametes versicolor

Indigo carmine (IC) was biotrasformed to 5-isatinsulfonic acid using intracellular and associated enzymes from null Trametes versicolor null lyophilized mycelia; even when extracellular enzymes were absent, in high concentration solutions of IC (4 000 mg L -1 ) and non-sterile condition. null T. versicolor null was grown in wheat strew and malt extract liquid medium and harvested during the stationary growth phase, it was lyophilized and made to...
