摘要:
A method of treating a biofilm on a surface, comprising: providing a surface having a biofilm; and administering to the surface a treatment that reduces a concentration of pyruvate of the biofilm, comprising pyruvate produced by at least a portion the biofilm, under conditions effective reducing maintenance of the biofilm on the surface. A composition, comprising purified enzyme, within a particle, effective for reducing pyruvate concentration in an aqueous suspension of the composition.
摘要:
At least one isolated microorganism, which converts at least 10% by weight, and preferably 50% by weight, of cellulosic biomass to a lower alkyl alcohol by direct digestion, and which produces at least 4% by volume of the lower alkyl alcohol in an aqueous-based digestion medium.
摘要:
The present invention relates to 16S-23S rRNA spacer sequences from Staphylococcus aureus and their use in a method for detection and/or identification of Staphylococcus aureus. The invention further relates to a method for detection and identification of Staphylococcus aureus in a sample, involving the steps of: (i) optionally releasing, isolating and/or concentrating the polynucleic acids present in the sample; (ii) optionally amplifying the 16S-23S rRNA spacer region, or a part thereof, with at least one primer pair; (iii) detecting the presence of a 16S-23S rRNA spacer sequence; and (iv) identifying the Staphylococcus aureus present in the sample from the nucleic acid(s) detected in the sample.
摘要:
The invention provides yitJ polypeptides and DNA (RNA) encoding yitJ polypeptides and methods for producing such polypeptides by recombinant techniques. Also provided are methods for utilizing yitJ polypeptides to screen for antibacterial compounds.
摘要:
A method for revealing the presence or absence of a particular microorganism strain in a medium, wherein at least one strain enzyme substrate chromogen and at least one compound selected from a high-concentration carbohydrate are added to the culture medium so that a derived colour differing from the basic colour of the chromophore is obtained once the chromogen has been hydrolysed.
摘要:
A vaccine against a microbial pathogen comprised of a live, immunogenic but prototrophic and avirulent mutant strain of the selected microbial pathogen in an amount effective to confer immunity. A method of obtaining a vaccine that induces a heightened cellular and humoral immune response to one of a variety of microbial pathogens in a warm blooded animal. A method for isolation of an avirulent strain of a selected pathogenic microorganism.
摘要:
A protein effective in stimulating cell growth activity. The protein has a molecular weight of from 5,000 to about 160,000, is composed predominantly of neutral and acidic amino acids, contains a significant amount of glutamic acid and aspartic acid, and is substantially free of nucleoside phosphotransferase. The protein is useful as wound treatment agent and as promoting agent in the synthesis of DNA. A method of producing the protein and compositions containing the same are also disclosed.
摘要:
Plasmid conferring resistance to streptomycin (Sm.sup.R) and neomycin (Neo.sup.R) upon its host (e.g. a Bacillus, Staphylococcus or Escherichia coli) and which after having taken up a foreign DNA fragment at one of its restriction sites with loss of its Sm.sup.R or Neo.sup.R phenotype, is still capable of replicating and expressing genetic information in its host.
摘要:
A probiotic organism which is capable of proliferation in iron-rich media, an environment which is generally unfavourable to probiotic organisms, is described.
