Fusarium polycaprolactone depolymerase is cutinase
Article Abstract:
Genetic, regulatory and enzymatic facts indicate that polycaprolactone (PCL) depolymerase from Fusarium, necessary for PCL utilization, is a cutinase. PCL is a synthetic polyester that is degraded by many microorganisms. A comparison of the wild-type and a mutant lacking the cutinase gene indicates that the mutants are unable to degrade PCL. There is PCL depolymerase and esterase activity of cutinase when the mutants are grown in cutin. A hydrolysate of PCL with PCL oligomers that resemble inducers of cutinase also induces PCL depolymerase activity in the mutants.

Enniatin production by Fusarium strains and its effects on potato tuber tissue
Article Abstract:
The production of enniatin is not needed for the infection of potato tuber tissue by the Fusarium species, but is required for the pathogenicity of the enniatin producing strains. Enniatin is a phytotoxin that causes necrosis in potato tuber tissues. The toxicity of Fusarium strains on the potato tuber tissue is analyzed by assaying the virulence on the tissue as enniatins stimulate necrosis of potato tissues in vitro.

Lignin degradation and modification by the soil-inhabiting fungus Fusarium proliferatum
Article Abstract:
Microbiological research shows that the soil-inhabiting microorganism Fusarium proliferatum can degrade lignin. Synthetic, natural and carbon-14 labelled lignin was used in comparative studies to ascertain degrading activity. Mineralization production occurs during primary metabolism. Residual products are also produced. The production process involves both depolymerization and polymerization activity.
