Abstract:
The new Bradyrhizobium sp. HCR-3 (KFCC 10770) (I) and HCR-46 (KFCC 10771) (II) for leguminous corp (III) are screened as the mutants to the seed disinfectant (IV). (I) is resistant to 300 microgram per milliliter of streptomycin and 250 microgram per milliliter of nalidisic acid as (IV), and (II) is to 250 microgram per milliliter of streptomycin, 150 microgram per milliliter of cephalexin, 200 microgram per milliliter of pimapsin and 250 microgram per milliliter of actidion. The preparation method for (III) consists of (1) culturing (I) and/or (II) for 10 days, (2) mixing the culture broth with arabic gum or carboxy methyl cellulose solution, and (3) seeding the prepared (III) with peanuts or red beans. After harvesting, (III) makes 17-34% yield increase.
