Metabolic reprogramming in the food-borne pathogen Listeria monocytogenes as a critical defence against acid stress.
The ability to sense and respond effectively to acidic stress is important for microorganisms to survive and proliferate in fluctuating environments. As specific metabolic activities can serve to buffer the cytoplasmic pH, microorganisms rewire their metabolism to favour these reactions and thereby mitigate acid stress. The orally acquired pathogen Listeria monocytogenes exploits alternative metabolic activities to overcome the acidic stress encountered in the human stomach or food products. In this minireview, we discuss the metabolic processes in L. monocytogenes that mitigate acid stress, with an emphasis on the proton-depleting reactions, including glutamate decarboxylation, arginine/agmatine deimination, and fermentative acetoin production. We also summarize the recent findings on regulatory mechanisms that control the expression of genes that are responsible for these metabolic activities, including the general stress response regulator SigB, arginine repressor ArgR, and the recently discovered RofA-like transcriptional regulatory GadR. We further discuss the importance of this metabolic reprogramming in the context of food products and within the host. Finally, we highlight some outstanding challenges in the field, including an understanding of acid-sensing mechanisms, the role of intraspecies heterogeneity in acid resistance, and how a fundamental understanding of acid stress response can be exploited for food formulation to improve food safety and reduce food waste.

Impact of chitin-derived β-N-acetyl-d-glucosaminyl-(1,4)-d-glucosamine on chitinase upregulation in Shewanella baltica.
The first steps in chitin degradation in marine bacteria involve chitinase, which produces N,N'-diacetylchitobiose (GlcNAc)2 from chitin. Moreover, in Vibrio bacteria, chitinase activity is enhanced by heterodisaccharide β-N-acetyl-d-glucosaminyl-(1,4)-d-glucosamine (GlcNAc-GlcN) produced from (GlcNAc)2 by chitin oligosaccharide deacetylase (COD). However, the role of COD in other marine bacteria, such as Shewanella, remains unexplored. This study investigates GlcNAc-GlcN's impact on chitinase gene expression and enzyme production in S. baltica ATCC BAA-1091, drawing parallels with Vibrio parahaemolyticus RIMD2210633. Using real-time quantitative PCR, the study assesses the upregulation of chitinase gene expression in S. baltica in response to GlcNAc-GlcN, informed by COD's known ability to produce GlcNAc-GlcN from (GlcNAc)2. In Vibrio, GlcNAc-GlcN considerably upregulates chitinase gene expression. This study posits a similar regulatory mechanism in S. baltica, with preliminary investigations indicating COD's capacity to produce GlcNAc-GlcN. This study highlights the importance of exploring GlcNAc-GlcN's regulatory role in chitin metabolism across diverse marine bacteria. The potential induction of chitinase production in S. baltica suggests broader ecological implications. Further research is crucial for a comprehensive understanding of chitin utilization and regulatory pathways in marine bacterial genera.
