The intermolecular electron transfer from Achromobacter cycloclastes pseudoazurin (AcPAZ) to wild-type and mutant Alcaligenes xylosoxidans nitrite reductases (AxNIRs) was investigated using steady-state kinetics and electrochemical methods. The affinity and the electron transfer reaction constant (k(ET)) are considerably lower between AcPAZ and AxNIR (K(m) = 1.34 mM and k(ET) = 0.87 x 10(5) M(-...

The affinity and the electron transfer reaction constant (kET) are considerably lower between AcPAZ and AxNIR (Km 1.34 mM and kET 0.87 10 5 M 1 s ) than betw...

The recombinant Pseudomonas putida strain CB1-9, which acquired the ability to grow on chlorobenzenes, contains a 33-kilobase (kb) plasmid (pKFL3) which lacked homology to an indigenous 15-kb plasmid (pKFL1) in Pseudomonas alcaligenes C-0 parent but was homologous to a 55-kb plasmid (pKFL2) from the P. putida R5-3 parent. Chromosomal DNA of P. alcaligenes C-0 hybridized to probes prepared from ...

Achromobacter, an aerobic, non-fermentative, Gram-negative rod is rarely isolated from clinical material. It can be confused with Pseudomonas spp. in clinical specimens, so that its role as a significant pathogen is underestimated. This organism was first described and named by Yabuuchi in 1971. (Yabuuchi & Oyama, 1971). Seven species are currently described within the genus Achromobacter, name...

Threonine aldolases catalyze the pyridoxal phosphate (PLP) dependent cleavage of threonine into glycine and acetaldehyde and play a major role in the degradation of this amino acid. In nature, L- as well as D-specific enzymes have been identified, but the exact physiological function of D-threonine aldolases (DTAs) is still largely unknown. Both types of enantio-complementary enzymes have a con...

Achromobacter spp. are emerging respiratory pathogens in cystic fibrosis patients. Since 2013 the genus Achromobacter includes 15 species for which innate antibiotic resistance is unknown. Previously the AxyXY-OprZ efflux system has been described to confer aminoglycoside (AG) resistance in A. xylosoxidans. Nevertheless, some Achromobacter spp. strains are susceptible to AG. This study includin...

Pseudomonas alcaligenes M-1 secretes an alkaline lipase, which has excellent characteristics for the removal of fatty stains under modern washing conditions. A fed-batch fermentation process based on the secretion of the alkaline lipase from P. alcaligenes was developed. Due to the inability of P. alcaligenes to grow on glucose, citric acid and soybean oil were applied as substrates in the batc...

Four nitrite-dissimilating strains, isolated from Weser Estuary sediments, were investigated using a polyphasic taxonomic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that these strains belong to the 'Betaproteobacteria' and are related to the genus Alcaligenes. The highest level of sequence similarity (100 %) was found with strain M3A (=ATCC 700596), a dimethyl su...

To analyze the status of the genus Alcaligenes in the agricultural environment, we developed a PCR method for detection of these species from vegetables and farming soil. The selected PCR primers amplified a 107-bp fragment of the 16S rRNA gene in a specific PCR assay with a detection limit of 1.06 pg of pure culture DNA, corresponding to DNA extracted from approximately 23 cells of Alcaligenes...
