Abstract: The disclosure relates to Paenibacillus polymyxa strains, compositions of the strains, anti-contaminant compositions, and methods of using the strains and compositions to inhibit growth of microorganisms, including pathogens causing spoilage of products, such as human food, pet food, and flowers.

Abstract: The present invention relates to anti-contaminant composition comprising a cell-free fermentation product of one or more Bacillus subtilis strains (e.g., selected from the group consisting of: 22C-P1, 15A-P4, 3A-P4, LSSA01, ABP278, BS 2084 and BS 18); wherein said fermentation product comprises one or more compounds selected from the group consisting of: a lipopeptide, a polyketide, a bacillibactin, a bacilysin, an anticapsin, a plantazolicin, a LCI, a homologue of a plantazolicin and a homologue of a LCI. In addition, the present invention further relates to methods of preparing the compositions, methods of using the composition, products comprising the composition and uses thereof.

Abstract: The present invention provides a composition comprising (a) an antimicrobial compound of the formula (I) wherein R1 is a fatty acid chain; R2 is a linear or branched alkyl residue having from 1 to 12 carbon atoms; n is an integer from 0 to 10; X? is selected from Br?, I?, Cl? and HSO4; (b) an antimicrobial material selected from lanthionine bacteriocins, tea [Camellia sinensis] extract, hop [Humulus lupulus L.] extract, grape skin extract, grape seed extract, Uva Ursi extract and combinations thereof.
