| streptomyces costaricanus sp. nov., isolated from nematode-suppressive soil. | a new bacterial strain, strain cr-43t (t = type strain), which was isolated from tropical soil and was previously shown to have antinematodal and antibiotic properties, is described. the name streptomyces costaricanus is proposed for this organism. the generic placement of strain cr-43t was based on its typical morphology, its production of ll-diaminopimelic acid, and its fatty acid composition. to clarify the taxonomic position of strain cr-43t, it was compared with the type strains of similar ... | 1995 | 7547298 |
| streptomyces aminopeptidase p: biochemical characterization and insight into the roles of its n-terminal domain. | we purified and characterized the aminopeptidase p from streptomyces costaricanus th-4 (thapp). this enzyme has a tetramer structure, a metal-ion preference toward zn, broad substrate specificity and a narrow ph dependency for activity. the primary structure of thapp, respectively, exhibits 91% and 65% identity with those of two other apps-app i and app ii-from streptomyces lividans (slapp i and slapp ii). we next overexpressed the genes encoding thapp and slapp ii in escherichia coli and charac ... | 2008 | 18156635 |
| suppression of meloidogyne hapla and its damage to lettuce grown in a mineral soil amended with chitin and biocontrol organisms. | chitin was used as soil amendment in fiberglass field microplots, alone or with one or a combination of two to three species of hirsutella rhossiliensis, paecilomyces marquandii, verticillium chlamydosporium, bacillus thuringiensis, and streptomyces costaricanus. sudangrass and rapeseed were planted as cover crops and incorporated into soil as green manure amendments. chitin amendment alone increased the marketable yield of lettuce in 1995 and reduced root-galling ratings and the reproduction of ... | 1999 | 19270942 |
| efficacy of bacillus thuringiensis, paecilomyces marquandii,and streptomyces costaricanus with and without organic amendments against meloidogyne hapla infecting lettuce. | chitin, wheat mash, or brewery compost were incorporated into unfumigated and methyl bromide-fumigated organic soils placed in microplots formed from cylindrical drainage tiles (0.25 m-diam. clay tile). after 3 weeks, meloidogyne hapla and cell or spore suspensions of bacillus thuringiensis, paecilomyces marquandii, and streptomyces costaricanus were individually added to the soils of designated microplots. a b. thuringiensis + s. costaricanus combination was also tested. lettuce seedlings, cv. ... | 2000 | 19270951 |
