Developments in bioprocess for bacterial cellulose production

Bacterial cellulose (BC) represents a novel bio-origin nonomaterial with its unique properties having diverse applications. Increased market demand and low yield are the major reason for its higher cost. Bacteria belonging to Komagataeibacter sp are the most exploited ones for BC production. Development of a cost-effective bioprocess for higher BC production is desirable. Though static fermentation modes have been majorly employed for BC production using tray fermenters, agitated mode has also been employed successfully with air-lift fermenters as well as stirred tank reactors. Bioprocess advances in recent years has led BC production to an upper level; however, challenges of aeration requirement and labor cost towards the higher end is associated with static cultivation at large scale. We have discussed the bioprocess development for BC production in recent years along with the challenges associated and the path forward.

Automated summary

Bacterial cellulose, a novel bio-origin nanomaterial with diverse applications, faces higher cost due to increased market demand and low yield. Komagataeibacter bacteria are commonly used for BC production. While static fermentation modes are predominantly utilized, agitated modes have also shown success. Bioprocess advancements have increased BC production, but challenges such as aeration requirements and labor costs are associated with large-scale static cultivation.
