Prophage Induction Causes Geobacter Electroactive Biofilm Decay

Environmental Science & Technology, Journal Year: 2023, Volume and Issue: 57(15), P. 6196 - 6204

Published: March 30, 2023

Sustaining a metabolically active electroactive biofilm (EAB) is essential for the high efficiency and durable operation of microbial fuel cells (MFCs). However, EABs usually decay during long-term operation, and, until now, causes remain unknown. Here, we report that lysogenic phages can cause EAB in Geobacter sulfurreducens cells. A cross-streak agar assay bioinformatic analysis revealed presence prophages on G. genome, mitomycin C induction to lytic transition those prophages, resulting progressive both current generation EAB. Furthermore, addition purified from decayed resulted accelerated EAB, thereafter contributing faster decline generation; otherwise, deleting prophage-related genes rescued process. Our study provides first evidence an interaction between bacteria suggests attack by primary decay, having significant implications bioelectrochemical systems.

Recent Advances in Thallium Removal from Water Environment by Metal Oxide Material

International Journal of Environmental Research and Public Health, Journal Year: 2023, Volume and Issue: 20(5), P. 3829 - 3829

Published: Feb. 21, 2023

Thallium is widely used in industrial and agricultural development. However, there still a lack of systematic understanding its environmental hazards related treatment methods or technologies. Here, we critically assess the behavior thallium aqueous systems. In addition, first discuss benefits limitations synthetic metal oxide materials that may affect practicality scalability TI removal from water. We then feasibility different for water by estimating material properties contaminant mechanisms four oxides (Mn, Fe, Al, Ti). Next, factors inhibit Tl conclude highlighting processes could serve as more sustainable alternatives to with further research

Methanogenesis in the presence of oxygenic photosynthetic bacteria may contribute to global methane cycle

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: July 6, 2024

Abstract Accumulating evidences are challenging the paradigm that methane in surface water primarily stems from anaerobic transformation of organic matters. Yet, contribution oxygenic photosynthetic bacteria, a dominant species water, to production remains unclear. Here we show methanogenesis triggered by interaction between bacteria and methanogenic archaea. By introducing cyanobacterium Synechocystis PCC6803 archaea Methanosarcina barkeri with redox cycling iron, CH 4 was induced coculture biofilms through both syntrophic (under anoxic conditions darkness) abiotic oxic illumination) during periodic dark-light cycles. We have further demonstrated other model various phyla, conjunction different exhibiting diverse energy conservation modes, as well common Fe-species. These findings revealed an unexpected link photosynthesis would advance our understanding bacteria’s ecological role global cycle. Such light-driven may be widely present nature.
