Abstract

Among commonly used probiotics, Bacillus has become a research hotspot due to its strong stress resistance, good stability, and tolerance to oxidation and acid/alkali. Additionally, Bacillus exhibits growth-promoting and disease-preventive effects, making it a potential alternative to antibiotics, a feed additive, and a water quality regulator. Currently, Bacillus species primarily studied in domestic aquaculture research include Bacillus subtilis, Bacillus licheniformis, Bacillus cereus, and Bacillus coagulans. In contrast, research on Bacillus lysine has mainly focused on isolation, screening, and identification. This article reviews the research progress of Bacillus lysine, covering its classification, functions, applications, and future prospects.
