The intended circular economy for plastics envisages that they will be partially replaced by bio-based polymers in the future. In this work, natural polyester polyhydroxybutyrate (PHB) was produced Azohydromonas lata using cheese whey (CW) as a low-cost substrate. Initially, CW evaluated sole carbon source PHB production; it found to efficient and comparable production with pure sugars, such sa...

Methane is abundant in marine subsurface sediments, sourced from microbial or thermocatalytic production. The relative composition of its isotopologues (12CH4, 13CH4, 12CH3D and 13CH3D) used to infer sources sinks. anaerobic oxidation methane (AOM) an important sink reaction carried out by consortia methanotrophic archaea (ANME) partner bacteria the presence sulfate. We investigated isotopologu...
