Identification and characterization of plant agmatine iminohydrolase, the last missing link in polyamine biosynthesis of plants
TLDR
Site‐directed mutagenesis of the two highly conserved cysteine residues of AIH showed that these cysteines are important but not essential for activity, arguing against a thioester substrate–enzyme intermediate during catalysis.
Influence of phytogenic surfactants (quillaya saponin and soya lecithin) on bio-elimination of phenanthrene and fluoranthene by three bacteria
TLDR
The results suggest that some phytogenic surfactants might improve PAH bioavailability in rhizospheres.
Plant C-N Hydrolases and the Identification of a Plant N-Carbamoylputrescine Amidohydrolase Involved in Polyamine Biosynthesis*
A nitrilase-like protein from Arabidopsis thaliana (NLP1) was expressed in Escherichia coli as a His6-tagged protein and purified to apparent homogeneity by Ni2+-chelate affinity chromatography. The
Distribution of polyamines in methanogenic bacteria
TLDR
The polyamine distribution found coincides with the dendrogram based on comparative cataloguing of 16S rRNA and offers a new, rapid chemotaxonomic method for characterizing methanogenic bacteria.
Rapid Differentiation, by Polyamine Analysis, of Xanthomonas Strains from Phytopathogenic Pseudomonads and Other Members of the Class Proteobacteria Interacting with Plants
A total of 58 strains belonging to phylogenetically assigned or unassigned species of the class Proteobacteria, which are mostly phytopathogenic or might interact with plants, were analyzed for
Isolation and Characterization of a Thermophilic, Sulfate Reducing Archaebacterium, Archaeoglobus fulgidus Strain Z
TLDR
An extremely thermophilic, strictly anaerobic sulfate reducing bacterium, strain Z, was isolated from sediments of a hydrothermal vent located near Mount Vulcanello, Vulcano, Italy, and shown to belong to the archaebacterial kingdom, representing another strain of Archaeoglobus fulgidus.
Distribution of polyamines in representative species of archaebacteria
TLDR
No specific polyamine composition was found to be typical of all archaebacteria investigated, but polyamine patterns were shown to be useful for their taxonomic evaluation.
Methanocorpusculaceae fam. nov., represented by Methanocorpusculum parvum, Methanocorpusculum sinense spec. nov. and Methanocorpusculum bavaricum spec. nov.
Two new methanogenic bacteria, Methanocorpusculum sinense spec. nov. strain DSM 4274 from a pilot plant for treatment of distillery wastewater in Chengdu (Province Sichuan, China), and
Ophiocordin, an antifungal antibiotic of Cordyceps ophioglossoides
TLDR
An unknown antibiotic, ophiocordin, was isolated from submerged cultures of Cordyceps ophioglossoides and could be demonstrated for a small number of fungi belonging to different taxonomic groups and antagonized by ammonia and nitrate ions and by certain amino acids.
Bioavailability of polycyclic aromatic hydrocarbons and formation of humic acid-like residues during bacterial PAH degradation
Abstract The degradation of single polycyclic aromatic hydrocarbons (PAHs: naphthalene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene and pyrene) and a mixture of all seven PAHs by a
