Abstract:
Surface-bound cellulases of cellulolytic bacteria are organized into discrete protuberances (cellulosomes). Cellulosome formation in the thermophilic actinomycete, Thermomonospora curvata, grown on cotton fibres, was visualized by cationic ferritin labelling under scanning electron microscopy. Mycelia attached to fibres, where substrate availability was greatest, had few cellulosomes. Mycelia found free in culture fluid, where substrate concentration was very low, had localized areas of profuse cellulosome formation.
