Recent progress in the characterization and application of exo-electrogenic microorganisms
Antonie Van Leeuwenhoek. 2024 Jan 3;117(1):10. doi: 10.1007/s10482-023-01916-y.ABSTRACTExo-electrogenic microorganisms are characterized by their special metabolic capability of transferring metabolic electrons out of their cell, into insoluble external electron acceptors such as iron or manganese oxides and electrodes, or vice versa take up electron from electrodes. Their conventional application is primarily limited to microbial fuel cells for electrical power generation and microbial electrolysis cells for the production of value-added products such as biohydrogen, biomethane and hydrogen peroxide. The utility of exo-el...

Nocardioides limicola sp. nov., an alkaliphilic alkane degrading bacterium isolated from oilfield alkali-saline soil
Antonie Van Leeuwenhoek. 2024 Jan 3;117(1):14. doi: 10.1007/s10482-023-01907-z.ABSTRACTA Gram-stain-positive, rod-shaped, non-spore-forming, alkane degrading bacterium, designated DJM-14T, was isolated from oilfield alkali-saline soil in Heilongjiang, Northeast China. On the basis of 16 S rRNA gene sequencing, strain DJM-14T was shown to belong to the genus Nocardioides, and related most closely to Nocardioides terrigena KCTC 19,217T (95.53% 16 S rRNA gene sequence similarity). Strain DJM-14T was observed to grow at 25-35 °C, pH 7.0-11.0, in the presence of 0-6.0% (w/v) NaCl. The predominant respiratory quinone was MK-8 (...

Edible plant oil (EPO)-consumption activity of the isolate Fusarium keratoplasticum EN01 and other relative Fusarium species
In this study, a mixed microbial strain EN00, which showed high edible plant oil (EPO)-consumption activity, was obtained from soil via enrichment cultivation. A fungal strain EN01 was isolated from EN00 and relegated to Fusarium keratoplasticum, based on the nucleotide sequences of the TEF1-α gene. Strain EN01 eliminated more than 90% of hydrophobic compounds from the medium containing 1.0% (w/v) EPO within 10 days at 30 °C. The rate of consumption of EPO by EN01 was comparable with that of EN00, suggesting that EN01 was the main microorganism involved in the EPO-consumption ability of EN00. Strain EN01 efficiently util...

Distribution and conservation of simple sequence repeats in plant pathogenic species of Zymoseptoria and development of genomic resources for its orphaned species
In this study, SSRs are defined as repeats of more than 12 bases in length. The genome and transcriptome sequences of Zymoseptoria ardabiliae show the highest RA (201.1 and 129.9) and RD (3229.4 and 1928.2) of SSRs, while those of Zymoseptoria pseudotritici show the lowest RA (167.2 and 118.5) and RD (2482.2 and 1687.0). The majority of SSRs in the genomic and transcriptome sequences of species were trinucleotide SSRs, while dinucleotide SSRs were the least common. The most common trinucleotide motifs in the transcriptomic sequences across all species were those that encoded the amino acid arginine. As per our motif conser...
