In-depth genomic characterization of petroleum hydrocarbon-degrading microorganisms<\/strong><\/p>\n<\/blockquote>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Microorganisms that can degrade petroleum hydrocarbons (alkanes and aromatic hydrocarbons) and utilize them as carbon and energy sources are considered to have acquired and conserve unique functional gene sets which encode specific enzymes that are responsible for bio-transformation of these hydrocarbons in their genomes.<\/p>\n\n\n\n

Through complete genome sequencing and comparative genomics analyses, we conduct in-depth genomic characterization of selected petroleum hydrocarbon-degrading microorganisms, for the purpose of identifying key functional genes in their genomes and discovering their novel metabolic potentials.<\/p>\n\n\n\n

Multispecies petroleum hydrocarbon biodegradation ‘ignited’ by pioneering bacteria in a soil bacterial consortium
<\/strong><\/p>\n<\/blockquote>\n\n\n

\n
\"\"<\/figure><\/div>\n\n\n

Microorganisms that are capable of biodegrading petroleum hydrocarbons and utilizing them as carbon and energy sources have been attracting interest for their potential roles in bioremediation. In natural environment, cooperative activities of multiple microbial groups are considered to be required to eliminate complex oil pollutant mixtures (alkanes and aromatic hydrocarbons), rather than a single microbial species.<\/p>\n\n\n\n

Our lab employs a combined metagenomic functional gene analyses and culture-based characterizations of the metabolic capabilities for the oil-degrading bacterial consortium members, to understand their complex roles and interactions developed during oil exposure.<\/p>\n\n\n\n

Our recent study using a diesel fuel-degrading soil bacterial consortium revealed that two pioneering members in the consortium, aromatics-degrading Sphingobium <\/em>and alkane-degrading Pseudomonas<\/em>, were responsible for initiating hydrocarbon biotransformations as well as the creation of specialized niches that were occupied by other bacterial members (co-colonizers). Co-existence of a select few pioneers and a multispecies co-colonizers cohort may be a common trait in natural ecosystems exposed to oil pollution.<\/p>\n\n\n\n

Ecology of freshwater Mn-oxidizing microorganisms; evaluation of their potentials for water purification
<\/strong><\/p>\n<\/blockquote>\n\n\n\n

A variety of microorganisms (bacteria and fungi) have the ability to oxidize dissolved Mn(II) and precipitate it as Mn(III\/IV) oxides. The Mn oxides produced by these microorganisms, the so-called Biogenic Mn Oxides (BMOs), are known to adsorb other heavy metals, and therefore are considered to have a potential to clean-up toxic heavy metal pollutants in water environments.<\/p>\n\n\n\n

Our current mission is to characterize the biomineralization and bioremediation potentials of a new Mn(II)-oxidizing fungal isolate, which was obtained from a Mn(II)-rich freshwater outflow located near the YCU campus.<\/p>\n\n\n\n

We isolated new genus of Zetaproteobacteria from deep ocean (Mid-Atlantic Ridge and Mariana back-arc), that can utilize molecular hydrogen as sole electron donor (in addition to ferrous iron). It is the first report of the hydrogen-oxidizing capability within the class Zetaproteobacteria.

Fe-rich pelagic lake aggregates (“iron snow”) generated by the Fe-cycling bacterial team

Pelagic lake aggregates enriched with Fe-oxides (called iron snow<\/em>) are formed by the simple bacterial community inhabiting in an acidic, Fe-polluted former lignite mining pit lake in Eastern Germany. These lake aggregates can be considered as a simplified model of bacterial interactions in the pelagic communities. We isolated a novel unique Fe-oxidizing bacterium Acidithrix<\/em>, which plays a central role to form iron-rich aggregates. Additionally, potential chemical cross-talking, co-aggregation system evolved between Acidithrix <\/em>and Fe-reducing Acidiphilium<\/em> was revealed by our metabolomics study, which is a rare example of bacterial inter-species chemical communication.

Conspicuous, streamer-forming microbial assemblages were observed in a former uranium-mining district in Eastern Germany. Our microbial community analyses and microscopic visualization revealed that the dominant Fe-oxidizing bacterium Gallionella<\/em> were colonizing macroscopic green algae Tribonema<\/em>, presumably utilizing algal exopolymer (i.e. EPS) to stick and dump the Fe-oxides.
