Abstract: Bacteriocins from lactic acid bacteria are kinds of natural proteins or peptides with antibacterial activities produced by lactic acid bacteria in the process of metabolism. They have the advantages of non-drug resistance, biodegradation, good antibacterial activity, etc., which have broad application prospects in food, medicine and feed fields. Based on bibliometrics, the literatures related to bacteriocins from lactic acid bacteria are searched in CNKI database and Web of Science (WOS) core collection database from 2000 to 2023, obtains 627 Chinese literatures and 2543 English literatures. CiteSpace software is used to analyze the research status and hot spots in this field from the perspective of annual number of published papers, core countries, authors, institutions and journals, highly cited literatures, keyword co-occurrence and co-clustering, etc.. The results show that the number of literatures has an increasing trend from 2000 to 2022. Spain, India and China are the top three countries in terms of number of literatures. The authors with the highest number of publications in CNKI database and WOS database are LI Pinglan from China Agricultural University and Todorov SD from University of Sao Paulo in Brazil, respectively. The journals with the highest number of publications are “Science and Technology of Food Industry” and “Journal of Appled Micbiogy”. In the CNKI database, keyword analysis reveals that most of the literatures are isolated, screened and identified from different food samples to obtain bacteriocin-producing lactic acid bacteria, and further evaluates the antibacterial activity of bacteriocins, and discusses the application in the food industry. The analysis of burst words shows that the focus of current research are antibacterial mechanism of bacteriocin and the relationship between bacteriocin and probiotics. In WOS database, the keywords of "gastrointestinal tract", "genetic characteristics", "Listeria mononucleogenes" and "antibacterial activity" appears more frequently. The main focus is the mining of bacteriocins from lactic acid bacteria toward antibiotic-resistant bacteria, and analysis of the genetic characteristics. The comprehensive analysis provides a reference and help for Chinese scientific researchers to engage in related research and predict the future development trend of the industry.
