pcs_fp_medium_for_thermophilic_cellulose_degradation

CultureMech:015439 bacterial COMPLEX LIQUID
Original name: PCS-FP medium for thermophilic cellulose degradation

Overview

pH
8.0
Notes
Vessel type: test tubes with loose caps PCS basal medium (peptone-cellulose-salt) supplemented with filter paper as cellulose substrate and calcium carbonate buffer. Medium prepared with loose caps to allow oxygen entry while maintaining high humidity. Static (non-shaking) incubation. The aerobic members (Pseudoxanthomonas, Brevibacillus, Bordetella) consume oxygen to create localized anaerobic microenvironments for the cellulolytic Clostridium species. Inoculum volume: 40 microliters per 4 mL medium. Subculture protocol: 40-700 microliters transferred to fresh medium after 6 days.
