Appl Microbiol Biotechnol 2022; 106:5449-5458. [PMID: 35902409 DOI: 10.1007/s00253-022-12103-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 07/08/2022] [Accepted: 07/24/2022] [Indexed: 11/28/2022]
Abstract
Biofilm-immobilized fermentation is a novel strategy that has been utilized in L-lysine fermentation. In this study, we describe a strategy for designing bioreactors for immobilized fermentation. We have constructed steel structures in which the carriers can be sewn, forming several star-like structures with different angles, and changing the ventilation robot to the aeration tray. In a 10-L bioreactor, this structure with 12 angles assisted the immobilized system to remedy the gap between free-cell and immobilized fermentation in the conversion rate. In a 50-L bioreactor, this enlarged structure with 16 angles illustrated a 4.61% higher conversion rate than the free-cell fermentation (67.75%) and increased the production by 28.56%. This successful case is the first step towards to industrial production of biofilm-based immobilized fermentation.Key points• The designed steel structure is useful for L-lysine immobilized fermentation in a 10-L bioreactor.• The conversion rate of immobilized fermentation increased from 13.99 to 60.07% and is 1.03% higher than that of the free-cell fermentation.• The conversion rate of the redesigned 50-L bioreactor is higher than that of free-cell fermentation.

Abstract
This review gathers recent information about genomic and transcriptomic studies in the Corynebacterium genus, exploring, for example, prediction of pathogenicity islands and stress response in different pathogenic and non-pathogenic species. In addition, is described several phylogeny studies to Corynebacterium, exploring since the identification of species until biological speciation in one species belonging to the genus Corynebacterium. Important concepts associated with virulence highlighting the role of Pld protein and Tox gene. The adhesion, characteristic of virulence factor, was described using the sortase mechanism that is associated to anchorage to the cell wall. In addition, survival inside the host cell and some diseases, were too addressed for pathogenic corynebacteria, while important biochemical pathways and biotechnological applications retain the focus of this review for non-pathogenic corynebacteria. Concluding, this review broadly explores characteristics in genus Corynebacterium showing to have strong relevance inside the medical, veterinary, and biotechnology field.
