摘要:
The invention concerns the application of compositions of micro-organisms in biological control of vine cryptogamic diseases. Said composition comprises a mixture of at least one bacterium and at least one yeast, the bacterium or bacteria and the yeast(s) being non-toxic for the plant. The invention also concerns bacterial and yeast strains, as well as biofungicide formulations containing an efficient amount of at least one composition of micro-organisms including in mixture at least one bacterium and one yeast, the bacterium or bacteria and the yeast(s) being non-toxic for the plant, and a composition of filamentous fungi, in particular of the genus Pichia, Pythium, Trichoderma, Gliocladium, Ampelomyces, Talaromyces, Epicococcum, combined with an inert carrier. The invention is useful for treating cryptogamic plant diseases, in particular crop plants and vine.
摘要:
A method for converting organic solid waste into humic products and the corresponding apparatus, in which a preliminary aerobic fermentation of the organic solid waste is performed, followed by a second aerobic fermentation of the organic waste in the presence of specific microorganisms in order to provide a basic precursor on which the selective metabolization occurs of specific bacterial strains to provide the humic product.
摘要:
A method for recovering silver from a refractory manganese dioxide-silver ore. The ore is contacted with an effective amount of a culture of direct manganese-reducing Bacillus polymyxa bacteria. The ore-bacteria mixture is maintained at an approximately neutral pH until a sufficient amount of the manganese dioxide in the ore is reduced from Mn(IV) to Mn(II). The silver present in the ore is then recovered by conventional methods such as cyanide leaching.
摘要:
The disclosure relates to a process for the microbiological modification of hardwood in that a microorganism, or an enzymatically active preparation thereof, specially selected for the hardwood in question, is supplied to the surface of the wood for attack thereof under carefully regulated conditions as regards temperature, relative moisture content, O.sub.2 content and CO.sub.2 content. Thereafter, the process is discontinued in a suitable manner, for example by treatment with steam or hot water, followed by drying; or by drying only.
摘要:
A method of determining the viable bacterial count of food which comprises incubating said food in a liquified agar medium which contains from 0.005 to 0.1 gram per liter of said liquified agar medium 2, 3, 5-triphenyl tetrazolium chloride as an inhibitor of bacteria colony spreading, and counting the bacteria colonies.
摘要:
This invention relates to a neutral protease useful for animal tissue cell culture and having the chemical and physical properties disclosed in the body of the specification, characterized in that said protease is produced by aerobically culturing a strain of Bacillus polymyxa deposited at the American Type Culture Collection, Rockville, Md. under accession number ATCC 21993 on a culture medium containing a suitable carbon source and nitrogen source.
摘要:
A novel extracellular enzyme complex precipitated from cultures of Bacillus NRRL B-3425 at critical concentrations selectively destroys the vegetative but not the sporulated cells of Bacillus popilliae or other spore-forming bacteria, thus providing a means for isolating laboratory-grown B. popilliae spores required for studying the apparently limited infectivity of the spores produced in vitro as compared with spores from diseased Japanese beetle larvae.
摘要:
A biodegradable resin molded article molded from a kneaded material obtained by kneading, melting or mixing a biodegradable resin raw material and at least one of a biodegradable additive and an additive made of a substance existing in the nature, an injection molded article of a biodegradable resin containing a biodegradable resin and an anti-biotic substance, a molded article of a resin composition including a polymer material having an ester bond in the polymer main chain thereof and an alkali or acid component in an amount effective for neutralizing an acidic or alkaline component contained in the polymer material, and a resin molded article having a layer of a biodegradable resin, and a layer of a photolytic resin covering the resin layer and containing an antibiotic.
