Innovative approaches to nisin production [PDF]

Applied Microbiology and Biotechnology, 2018
Nisin is a bacteriocin produced by Lactococcus lactis that has been approved by the Food Drug Administration for utilization as a GRAS status food additive. Nisin can inhibit spore germination and demonstrates antimicrobial activity against Listeria, Clostridium, Staphylococcus, and Bacillus species.

In vivo activity of Nisin A and Nisin V against Listeria monocytogenesin mice [PDF]

BMC Microbiology, 2013
Abstract Background Lantibiotics are post-translationally modified antimicrobial peptides, of which nisin A is the most extensively studied example. Bioengineering of nisin A has resulted in the generation of derivatives with increased in vitro potency against Gram-positive bacteria.

Physiochemical parameters optimization for enhanced nisin production by Lactococcus lactis (MTCC 440)

Brazilian Archives of Biology and Technology, 2010
The influence of various physiochemical parameters on the growth of Lactococcus lactis sub sp. lactis MTCC 440 was studied at shake flask level for 20 h. Media optimization (MRS broth) was studied to achieve enhanced growth of the organism and also nisin

From senescence and inflammaging to systemic comorbidities: Drivers of aging‐associated periodontitis

Periodontology 2000, EarlyView.
Abstract Background Aging is accompanied by a chronic low‐grade inflammatory process, known as inflammaging, as well as immunosenescence, an age‐related decline and dysregulation of immune function, and cellular senescence, a process in which cells enter a state of irreversible growth arrest while actively releasing pro‐inflammatory factors.

Of mice and men—The emerging oral–gut–brain axis of health and disease

Periodontology 2000, EarlyView.
Abstract Objectives Oral health's inextricable links to systemic health are highlighted by the emerging oral–gut–brain axis and other well‐known axes. There is growing evidence of a complex oral–gut–brain axis linking mouth and gut microbiomes with the central nervous system.

The Lipoteichoic Acid-Related Proteins YqgS and LafA Contribute to the Resistance of Listeria monocytogenes to Nisin

Microbiology Spectrum, 2022
Listeria monocytogenes is a major pathogen contributing to foodborne outbreaks with high mortality. Nisin, a natural antimicrobial, has been widely used as a food preservative. However, the mechanisms of L. monocytogenes involved in nisin resistance have

Recent and Promising Strategies for Robust, Sustainable, and Cost‐Friendly Production of Yogurt With Superior Quality

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Yogurt is one of the most technologically mature fermented dairy products on the market, traditionally prepared using the two lactic acid bacteria (LAB) Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus. Global demand for yogurt continues to rise, driven by consumer interest in healthy, high‐protein diets with as few ...

The Assay of the Antibiotic Nisin [PDF]

Journal of General Microbiology, 1950
SUMMARY: Nisin, which does not diffuse quickly through agar, may be assayed by dilution methods; or, because it is bactericidal and not merely bacteriostatic, it may be assayed by estimating numbers of surviving bacteria. Nisin in low sublethal concentration simply prolongs the lag-phase of Streptococcus agalactiae; in higher sublethal concentrations ...
