Its antagonistic activity is conferred by its ability to produce bioactive secondary metabolites such as the Heat-Stable Anti-Fungal Factor (HSAF), Heat-Stable Degrading Metabolite (HSDM) and WAP-8294A2. It can also produce abundant lytic enzymes such as; <em>chitinases</em><em>, proteases, glucanases</em> and <em>cellulases</em> that can degrade fungal cell walls and therefore inhibit their growth. To design effective biocontrol strategies employing <em>L. enzymogenes</em>, it is important to understand its antagonistic mechanisms. This review crystalizes information on the biosynthesis mechanisms and biocontrol mechanisms of various antimicrobial compounds produced by <em>L. enzymogenes</em>, this information is essential in designing biocontrol strategies against phytopathogens. Further, this review highlights the uncharacterized HSDM and proposes the need for its future characterization, determination of its biosynthetic gene cluster and characterization of its antagonistic mechanisms against various phytopathogens. Also, the mechanism of <em>clp</em> regulation of lytic enzymes biosynthesis needs to be further studied.</p> Benard Odhiambo Copyright (c) 2021 Benard Odhiambo https://creativecommons.org/licenses/by-nc-nd/4.0 https://panafricajournal.com/index.php/home/article/view/9 Mon, 13 Sep 2021 00:00:00 +0000
