- 1 November 1993
Preliminary glasshouse experiments indicated that some of the actinomycetes protect germinating lettuce seeds against damping-off caused by P. ultimum, and some correlations between delayed seed germination and reduced 18-day plant biomass yields were seen.
Novel Plant-Microbe Rhizosphere Interaction Involving Streptomyces lydicus WYEC108 and the Pea Plant (Pisum sativum)

It is hypothesized that root and nodule colonization is one of several mechanisms by which Streptomyces acts as a naturally occurring plant growth-promoting bacterium in pea and possibly other leguminous plants.
Characterization of streptomyces lydicus WYEC108 as a potential biocontrol agent against fungal root and seed rots
The actinomycete Streptomyces lydicus WYEC108 showed strong in vitro antagonism against various fungal plant pathogens in plate assays by producing extracellular antifungal metabolites. When Pythium…
Characterization of an extracellular lignin peroxidase of the lignocellulolytic actinomycete Streptomyces viridosporus
- M. Ramachandra, D. Crawford, G. Hertel
- Biology, ChemistryApplied and environmental microbiology
- 1 December 1988
This is the first report of a lignin peroxidase in a bacterium designated as ALiP-P3 and characterizations showed that this enzyme is a heme protein (Soret band, 408 nm) and a major component of the ligninolytic system of S. viridosporus T7A.
Initial-phase optimization for bioremediation of munition compound-contaminated soils
- S. Funk, D. Roberts, D. Crawford, R. Crawford
- Biology, EngineeringApplied and environmental microbiology
- 1 July 1993
Completion of the first stage of remediation of munition compound-contaminated soils resulted in aqueous supernatants that contained no munition residues or aminoaromatic compounds.
Lignin Degradation by Streptomyces viridosporus: Isolation and Characterization of a New Polymeric Lignin Degradation Intermediate
- D. Crawford, A. Pometto, R. Crawford
- Medicine, ChemistryApplied and environmental microbiology
- 1 March 1983
The lignin origin of APPLs was confirmed by chemical analyses, which included acidolysis, permanganate oxidation, elemental analyses, functional group analyses, nuclear magnetic resonance spectroscopy, and C isotopic techniques.
Lignocellulose decomposition by selected streptomyces strains
- D. Crawford
- BiologyApplied and environmental microbiology
- 1 June 1978
It was shown that purified 14C-labeled milled-wood lignin was attacked, with recoveries of up to 17.7% of the label was 14CO2, the first conclusive evidence to show that streptomycetes can decompose lignIn.
"Actinomycetes, promising tools to control plant diseases and to promote plant growth"
La revue donne aussi des exemples de lutte biologique contre les agents phytopathogenes bacteriens and fongiques par l’utilisation d’especes d‘actinomycetes deja disponibles sur le marche ou qui le seront probablement au cours des prochaines annees.
Metabolism of cinnamic, p-coumaric, and ferulic acids by Streptomyces setonii.
Streptomyces setonii strain 75Vi2 was grown at 45 degrees C in liquid media containing yeast extract and trans-cinnamic acid, p-coumaric acid, ferulic acid, or vanillin. Gas chromatography,…
