TL;DR: Results clearly show that marine sediments can be used as microbial sources for methane production from algae under high-salt conditions without dilution.

TL;DR: A methanogenic microbial community was developed from marine sediments to have improved methane productivity from brown algae under high salinity thanks to enhanced acetoclastic methanogenesis because acetate became rapidly converted to methane during cultivation.

TL;DR: Enzyme production, major fermentation products from glucose, and the major cellular fatty acids were different from those of D. capnocytophagoides CCUG 17966T or other members of the genus Dysgonomonas.

TL;DR: Results indicated that the acclimated marine sediment culture was able to produce methane semi-continuously from raw brown algae without dilution and nutrient supply under steady state, and suggested that hydrogenotrophic methanogens predominated among archaea during unstable methane production.

TL;DR: Alginate lyase activity and metagenomic analyses, based on high-throughput sequencing data, revealed that this bacterial consortium possessed putative genes related to a predicted alginate metabolic pathway, suggesting the existence of bacterial interactions like symbiosis for anaerobic alginates degradation.
