Abstract: The present invention relates to an anti-inflammatory use of macrolactin compounds such as macrolactin A, 7-O-malonyl macrolactin A and 7-O-succinyl macrolactin A, which are produced from a novel Bacillus strain of Bacillus polyfermenticus KJS-2 (KCCM10769P). The macrolactin compounds provided by the present invention were confirmed to greatly suppress the expression and formation of inducible nitric oxide synthetase (iNOS) and cyclooxygenase-2 (COX-2) which are proteins related to the formation of inflammatory mediators, and to accordingly inhibit the formation of nitric oxide (NO) and of prostaglandin E2 (PGE2) which are the metabolites of the proteins. In addition, the macrolactin compounds provided by the present invention were confirmed to have excellent effects in inhibiting the formation of tumor necrosis factor-alpha (TNF-?), interleukin-1? (IL-1?), interleukin-6 (IL-6) and granulocyte macrophage colony-stimulating factor (GM-CSF), which are pro-inflammatory cytokines.

Abstract: The present invention relates to uses of Macrolactin A produced by Bacillus polyfermenticus KJS-2 (KCCM 10769P), which is a new bacillus strain, as an antibiotic. Macrolactin A of the present invention, which is produced by Bacillus polyfermenticus KJS-2, shows a broad spectrum of antibiotic activity against a variety of microorganisms and fungi, and is proved to be very efficient for the inhibition of particularly vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus Aureus (MRSA) that are multidrug-resistant bacteria. The antibiotic Macrolactin A produced by Bacillus polyfermenticus KJS-2, can be used as an excellent antibiotic against vancomycin-resistant enterococci (VRE) and methicillin-resistant Staphylococcus Aureus (MRSA), and thus the present invention is a very useful invention for medical industry.

Abstract: Disclosed herein are novel microbes Thraustochytrium sp. KJS-1 and Bacillus polyfermenticus KJS-2. Also provided is an aquaculture feed additive for use in fisheries, which comprises freeze dried Thraustochytrium sp. KJS-1, freeze dried Bacillus polyfermenticus KJS- 2, and freeze dried Bacillus licheniformis. In addition to providing DHA, an essential nutrient for fish, the aquaculture feed additive shows antibacterial and antifungal activity, thereby preventing fish from dying from bacterial and fungal diseases.
