Biocomposites Using Whole Cell

There are many strategies for whole cell immobilization playing the biocatalyst role in the biorefinery processes. Suto and co-workers studied the 

The production of SA was studied with entrapped and adsorbed Actinobacillus succinogenes on varied supports (e.g., diatomite or zeolite, approx. 12.6 mg/g support) [136], Higher productivities in SA were achieved with A. succinogenes entrapped in agar beads. After 5 cycles (72 h) repeated batch fermentations with immobilized cells in agar, the production of SA was 107 g/L. These approaches reduced significantly the fermentation time and improved the process yield, productivity, and final concentration in SA [136]. 

Research in chemistry of materials for the past decades demonstrated that designing new architectures based on the nano-entities assembling may provide synergetic effects. 

The discovery and investigation of novel and efficient cata-lysts/pathways for the conversion of biomass into chemicals are among the big challenges facing heterogeneous catalysis/ biocatalysis. 

The specific properties of biomass pose new requirements on the processes and on the solids that have to be used as catalysts. The novel Ru-based magnetic nanoparticles systems meet these criteria. Also, enzyme biocomposites (e.g., lipase, peroxidase, (3-galactosidase) behave properly in the biomass valorization process.
