Antibiotic resistance genes fate during food waste management - Comparison between thermal treatment, hyperthermophilic composting, and anaerobic membrane bioreactor.

The fate of eight different antibiotic resistance genes (ARGs) in food waste (sul1, sul2, tetO, tetW, ermF, ermB, ampC, oxa-1), intI1, and rpoB were monitored during thermal treatment (pyrolysis and incineration), hyperthermophilic composting, and anaerobic membrane bioreactor (AnMBR) treatment. ARGs in food waste ranged from 2.9 × 10 to 3.

Metagenome-Assembled Genomes from Photo-Oxidized and Nonoxidized Oil-Degrading Marine Microcosms.

We performed deep metagenomic sequencing on hydrocarbon-degrading marine microcosms designed to experimentally determine the effect of photo-oxidation on oil biodegradation dynamics. Assembly, binning, and dereplication yielded 73 unique metagenome-assembled genomes (MAGs) from 6 phyla, of which 61 are predicted to be over 90% complete.
