Abstract:
PURPOSE: A novel Pseudomonas aeruginosa NO3 strain which produces antibiotics to bacterial canker and mutant thereof are provided to bacterial canker. CONSTITUTION: A novel Pseudomonas aeruginosa NO3(KFCC 11444P) produces antibiotics material to bacterial canker. The bacterial canker is Xanthomonas citri or Pseudomonas syringae pv actinidiae. The antibiotics contain linollenic acid. The Pseudomonas aeruginosa is obtained by hybridizing miniTn5::tet transposon.
Abstract:
A novel Bacillus sp. CMB32 is provided to be used for producing an antibacterial material from a culture material thereof. And a controlling agent of plant pathogenic bacteria comprising the same is provided to be used as an insecticide for preventing and treating injurious insects and mold. A Bacillus sp. CMB32 which is antagonistic strain of plant pathogens is deposited as a deposition no. KCTC 10940BP. An antibiotic material such as iturin A, fengycin and surfactin A is produced from a culture material obtained by culturing the Bacillus sp. CMB32. A controlling agent of plant pathogenic bacteria comprises the Bacillus sp. CMB32 or a culture solution thereof.
Abstract:
Antibiotics comprising eicosapentaenoic acid as an active ingredient are provided to inhibit growth of gram positive pathogenic bacteria and antibiotic-resistant strains commonly occurring in human and animals, and produce a large quantity of eicosapentaenoic acid by treating eicosapentaenoic acid derivatives obtained from the strain with a protein-decomposing enzyme. The antibiotics comprise an eicosapentaenoic acid as an active ingredient, wherein the daily dosage of eicosapentaenoic acid is 1-2 mg/kg, preferably 0.5-1 mg/kg. A Pseudomonas sp. CJM01(KCTC 10941BP) strain having antibiotic activity against gram positive bacteria produces the eicosapentaenoic acid and is isolated from the soil. The animal feed additives or microorganism sterilizer comprises Pseudomonas sp. CJM01(KCTC 10941BP) strain or Pseudomonas sp. CJM01(KCTC 10941BP) strain cultured medium.
