Transformation of Azotobacter vinelandii with plasmid DNA [PDF]

Journal of Bacteriology, 1985
Azotobacter vinelandii cells can be transformed at high frequencies with the broad-host-range plasmids pRK2501, RSF1010, and pGSS15, using a modification of the procedure developed by Page and von Tigerstrom (J. Bacteriol. 139:1058-1061, 1979) for chromosomal DNA-mediated transformation.

Enzymatic and microbial routes to bioplastics: The green chemistry frontier of biopolymers

FEBS Open Bio, Volume 16, Issue 4, Page 709-726, April 2026.
Microbial biosynthesis and engineered enzyme platforms are expanding the design space of polyhydroxyalkanoate bioplastics. By combining fermentation, PHA synthase engineering and cell‐free modular systems, tailored biodegradable polymers can be produced with tunable properties, supporting more sustainable materials and future circular bioeconomy ...

Identification of sulfurtransferase enzymes in Azotobacter vinelandii [PDF]

FEBS Letters, 1991
Rhodanese and 3‐mercaptopyruvate sulphurtransferase have been identified in A. vinelandii. Two distinct active fractions of the two sulphurtransferases were obtained after FPLC ion‐exchange chromatography of material partially purified from crude extracts. Rhodanese has been purified to homogeneity, and it consists of one polypeptide chain of M r ca 25

Electroenzymatic Cascades for Nitrogen Upgrading: Beyond Ammonia Towards Value‐Added Nitrogen Chemicals

ChemCatChem, Volume 18, Issue 7, 14 April 2026.
This review maps how electroenzymatic cascades that couple nitrogen‐cycle enzymes with C─N bond forming auxilary enzymes, powered by direct electron transfer (DET) or mediated electron transfer (MET), can upgrade N2 and waste nitrogen streams into value‐added amines, amides, amino acids, and other nitrogen‐based chemicals.

A Foundation for Advancing Studies of the Biodegradation of Polyethylene Surrogates by Environmental and Model Laboratory Microbes

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
A polyethylene surrogate sample containing paraffin, polywax and polyethylene was exposed to selected microbes identified in this study. This image shows the surface of this surrogate following a six‐week incubation with Rhodococcus jostii. ABSTRACT Polyethylene represents a particularly recalcitrant class of plastics that persist for decades in the ...
