Abstract:
PURPOSE: Provided are Stenotrophomonas maltophilia A-2 (KCTC 0659 BP) and 51-4 (KCTC 0658 BP) which biologically decompose aniline and its derivatives contaminating soil, underground water, stream, pond or waste water. CONSTITUTION: Stenotrophomonas maltophilia A-2 (KCTC 0659 BP) or 51-4 (KCTC 0658 BP) is obtained by the following steps of: i) cultivating water sample from a stream at minimum medium containing aniline at 30 deg.C at 200rpm for seven days; ii) checking if aniline is decomposed on the medium; iii) inoculating the broth into PTYG agar plate containing 300μg/ml of aniline and separating purely colonies; and iv) cultivating the colonies in broth containing aniline. The two strains purified here are all gram-negative. And the bacteria decompose aniline between pH 5.0-9.0, preferably pH 6.0-8.0, most preferably pH 7.0.
Abstract:
PURPOSE: An Acremonium strictum strain, hyperparasite of Botrytis cinerea and a method for inhibiting diseases caused by Botrytis cinerea using the same are provided for substituting chemical insecticides with biological insecticides, so that they do not cause the contamination of nature. CONSTITUTION: Acremonium strictum BCP strain (KCTC 0639BP) is hyperparasite of Botrytis cinerea and is useful in inhibiting and treating the diseases caused by Botrytis cinerea. All plants, which may be infected by Botrytis cinerea, such as cucumber and tomato, may be treated with Acremonium strictum BCP strain (KCTC 0639BP) in an effective amount so as to inhibit plant diseases, in which the amount of Acremonium strictum BCP strain (KCTC 0639BP) is in the range of 1x104 to 3x108 spores/ml, preferably 1x106 to 3x107 spores/ml.
