摘要:
An isolated bacteriophage MR299-2 or NH-4 deposited under NCIMB Deposit Accession Nos. 41729 and 41730, respectively, is described. The phages have lytic activity against P. aeruginosa strains, including mucoid and CF clinical isolate strains. Variant hages are also described, wherein said variants retain the phenotypic characteristics of said phage and wherein said phage and variants thereof have lytic activity against P. aeruginosa strains.
摘要:
The present invention relates to a new bacteriocin, to microbial strains which can produce it and to uses of the bacteriocin and the strains. The bacteriocin is effective against Clostridium difficile and Listeria monocytogenes amongst other organisms.
摘要:
The invention provides a probiotic composition to alleviate Salmonella infection in farm animals. The composition may comprise at least one of Lactobacillus murinus, Lactobacillus pentosus, Lactobacillus salivarius sub-species salivarius, and Pediococcus pentosaceus. The composition maybe formulated as an animal feedstuff, or as a pharmaceutical composition.

摘要:
The present invention relates generally to the field of health promoting agents, in particular antimicrobial agents and provides antimicrobial peptides and bacterial strains that provide the antimicrobial peptides. In one aspect, the invention provides a biologically pure culture of Lactobacillus acidophilus, strain DPC6026, a sample of which has been deposited at the National Collection of Industrial and Marine Bacteria, Aberdeen, Scotland on 18th Nov. 2005 under the accession number NCIMB 41354, or a derivative or mutant thereof capable of producing from milk or a milk product, peptides having antimicrobial activity.
摘要:
The present invention relates to a novel anti-microbial agent, more particularly, a novel bacteriocin with nisin-like properties. The bacteriocin is designated lacticin 3147 and has the following properties: a molecular weight of approximately 2.8 kDa; inhibiting activity against lactococci, lactobacilli, enterococci, bacilli, leuconostocs, pediococci, clostridia, staphylococci and streptococci; sensitivity to the proteases trypsin, alpha-chymotrypsin, proteinase K and pronase E but not pepsin; heat-stability; activity at acid pH; and the capability of inhibiting nisin-producing bacterial strains.
摘要:
The disclosure relates to the live cultures of probiotic bacteria to treat infectious diseases in humans and animals. Food-grade or non-pathogenic cultures are used to treat localised infections.
摘要:
The production of a spray-dried bacteriocin lacticin 3147 powder is described. The powder is shown to have effective anti-microbial activity in a range of foodstuffs, namely infant milk formulations, powdered soup, yoghurt and cottage cheese. Increased anti-microbial activity was demonstrated when the lacticin 3147 powder was used in conjunction with increased hydrostatic pressure. The process comprises: inoculating a medium with a lacticin 3147-producing strain of bacteria, fermenting the inoculated medium, adjusting the pH of the fermentation to 6.3-6.7, inactivating the bacterial fermentate and evaporating the fermentate.
