D-lactate dehydrogenase gene (ldhD) inactivation and resulting metabolic effects in the Lactobacillus johnsonii strains La1 and N312
Article Abstract:
Research was conducted to examine D-lactate dehydrogenase (D-LDH) gene (ldhD) inactivation and resulting metabolic effects in the Lactobacillus johnsonii strains La1 and N312. The ldhD was isolated and an in vitro-truncated copy of the gene was utilized to inactivate the genomic copy in the two strains by gene replacement. Results indicate that D- and L-LDH exist in substantial excess in L johnsonii for their role to eliminate pyruvate and regenerate NAD+.

Isolation and identification of actinobacteria from surface-sterilized wheat roots
Article Abstract:
Research has been conducted on filamentous actinobacteria from the surface-sterilized roots of wheat plants. The authors describe the isolation, identification and characterization of these bacteria, and discuss bacteria's role in pathogen defence and growth regulation of their hosts.
