摘要:
The present invention provides formulations and methods for controlling or suppressing bacterial or fungal plant pathogens, including Erwina amylovora the bacteria that causes fire blight. A formulation for controlling of suppressing a plant pathogen may include at least one beneficial species of bacteria, at least one beneficial species of fungi, a nutrient, at least one compound that extends the length of time that the formulation remains effective. Typically the formulation is applied to the above ground structures of the plant including its leaves, flowers, stems, trunk, blossoms and fruit.
摘要:
A method for DNA reassembly after random fragmentation, and its application to mutagenesis of nucleic acid sequences by in vitro or in vivo recombination is described. In particular, a method for the production of nucleic acid fragments or polynucleotides encoding mutant proteins is described. The present invention also relates to a method of repeated cycles of mutagenesis, shuffling and selection which allow for the directed molecular evolution in vitro or in vivo of proteins.

A process for the production of organic and combination formulation of bio-pesticide containing Trichoderma harzianum and Pseudomonas fluorescens comprising preparation of mother culture, liquid fermentation as well as solid fermentation of T. harzianum, preparation of mother culture, liquid fermentation as well as solid fermentation of P. fluorescens separately, followed by mixing both the bio-pesticides in the proportion of 1-2:1-2: preferably 1:1 to get the final combination, formulation.
摘要:
A method and composition for bioremediation of environmental material. In one embodiment, material to be bioremediated is debris is obtained from a metropolitan street cleaning operation. An environmentally safe all natural non-pathogenic microbial composition is used under conditions sufficient to bioremediate the material.
摘要:
A process for recovering a desired organic acid from a solution includes the steps of: providing an aqueous solution including at least one desired organic acid or its acid anion; adjusting the proton concentration in the aqueous solution to a desired level, with the desired proton concentration being selected, at least in part, by the amount of available protons needed to associate with the acid anions of the desired organic acid(s) to be recovered and/or acid anions that are weaker than the desired organic acids; and recovering at least a portion of the at least one desired organic acid from the aqueous phase. The desired proton concentration can be based on the amount of available protons being greater than, less than or substantially equal, to the amount of protons needed to associate with the anion of the desired organic acid(s) and acid anions that are weaker than the desired organic acid(s). Specific examples of suitable organic acids include, but are not limited to, ascorbic, succinic, tartaric, glyconic, gulonic, citric, lactic, hialic, maleic, acetic, formic, gluconic pyruvic, propionic, butyric, itaconic acids and mixtures thereof. One embodiment of the present invention relates to the recovery of 2-keto-L-gulonic acid (KLG) from aqueous solutions such as fermentation baths.

A method for producing a microbial polyester by culturing a microorganism being capable of producing a poly hydroxyalkanoate polyester in a culture medium containing 1-hexene as a sole carbon source.
摘要:
A method is disclosed for conditioning samples (of e.g. milk or meat) containing fat globules and somatic cells and/or protein particles before they are subjected to fluorescence measurements in order to determine the bacterial content, as well as methods for performing the determination of bacterial content in such samples. The conditioning method involves the treatment of the samples with an ion-chelating agent, a proteolytic enzyme, detergent, and a bacteriologically specific fluorochrome such as ethidium bromide. Detergent is used in a concentration resulting in substantially no dissolution of the fat globules and the conditioned samples thus loses insignificant amounts of fat globules. The assessment of fluorescence is preferably performed in a conventional flow cytometer. As no separation of fat globules is necessary, the methods are simple and fast. The bacterial determinations have proved reliable when compared to standard methods.
摘要:
This invention provides a process for the production of .delta.-decalactone by the microbial reduction of massoia lactone, characterized in that a bacterium having the ability to reduce massoia lactone is used as the microorganism. The .delta.-decalactone produced according to this process has a highly tastable, mild creamlike scent and flavor, and is hence suitable for use in flavor compositions.
