Production of Metabolites as Bacterial Responses to the Marine Environment

open access: yesMarine Drugs, 2010
Bacteria in marine environments are often under extreme conditions of e.g., pressure, temperature, salinity, and depletion of micronutrients, with survival and proliferation often depending on the ability to produce biologically active compounds.

Anaerobic degradation of dimethylsulfoniopropionate to 3-S-methylmercaptopropionate by a marine Desulfobacterium strain [PDF]

open access: yes, 1993
Dimethylsulfoniopropionate, an osmolyte of marine algae, is thought to be the major precursor of dimethyl sulfide, which plays a dominant role in biogenic sulfur emission.

Marine Denitrifying Bacteria from South India [PDF]

open access: yesJournal of General Microbiology, 1956
Thirty-two isolates from a number obtained from sea water off the South Indian coast, from marine sand and from molluscs, proved to be denitrifiers. The reactions of 20 of these strains on different media show that they fall into five groups; all are considered to be species of Pseudomonas, and two of the groups to be new species.

Alternating High‐Fat and Polysaccharide Diets Modulates Gut Phage‐Bacterial Interplay

open access: yesAdvanced Science, EarlyView.
This study reveals how alternating high‐fat and polysaccharide diets reshape the human gut virome and enhance phage‐bacteria interactions. Using large‐scale metagenomic meta‐analysis and a time‐resolved mouse model, the authors show that diets strongly modulate phage abundance, lifestyle, and gene exchange, offering new insights into nutrition‐guided ...
