Abstract:
A novel strain is provided to solubilize insoluble-phosphate excellently within a short time, prevent solubilized phosphate from being fixed on soil due to reusing the solubilized phosphate at a rapid rate, and supply phosphoric acid, which is necessary for a plant, efficiently by gradually releasing the solubilized phosphate into the soil again. A Pseudomonas sp. CL-1 strain solubilizing insoluble-phosphate fixed on soil is deposited as a deposition no. KACC 91282P. A biofertilizer comprises a fungus body or a culture solution of the Pseudomonas sp. CL-1 strain. To solubilize the insoluble-phosphate fixed on the soil, the strain or the fertilizer is directly applied to the soil.
Abstract:
A feed additive is prepd. by innoculating medium contg. bean-curd refuse, rice bran and food sludge with bacillus brevis AS91B KFCC 10781, and fermenting at room temp. and aerobic condition for 25-35 days. The strain is obtd. from soybean malt, soybean paste, fermented soybean or kimchi.
Abstract:
PURPOSE: A medium for culturing fungi with excellent fungi growth ability is provided to cheaply and easily distinguish eco-friendly organic agricultural materials. CONSTITUTION: A medium for culturing fungi contains 2.5% of anhydroglucose, 1.8 weight% of yeast extract, 0.02% of bay salt, agar, and remaining amount of water. The medium is used for testing activity of eco-friendly organic agricultural materials. The fungi are Colletotrichum gloeosporioides.
Abstract:
PURPOSE: Thermophilic microorganisms having improved organic matter decomposing activity are provided. The microorganisms can grow at high temperature of 60 deg. C or more and effectively decompose organic matter. Therefore, compost can be effectively prepared. CONSTITUTION: A microbial preparation for accelerating decomposition of organic matters comprises thermophilic microorganisms Bacillus stearothermophillus NIAST, Chaetomium thermophile NIAST and Thermoactinomyces NIAST. A method for culturing thermophilic microorganisms comprises the steps of: inserting a sterilized medium into a culture vessel; inoculating the thermophilic microorganisms into the medium; culturing the thermophilic microorganisms at an appropriate temperature with supplying air.
