Methods and devices for monitoring the viability of a biofilm comprising Pseudomonas Aeruginosa bacteria are provided by detecting pyocyanin. The invention relates to electrochemical methods and devices that offer a simple and inexpensive alternative for immediate identification of bacterial infection due to the presence of Pseudomonas aeruginosa. In some embodiments, an inexpensive, disposable electrochemical sensor can be used to rapidly screen for the presence of P. aeruginosa in clinical wound effluent samples.

A method of reducing a concentration of N.sub.2O, NO, or a combination thereof in a medium, the method comprising: culturing a microorganism of the genus Paracoccus, a microorganism of the genus Pseudomonas, or a combination thereof in a liquid medium comprising Mg.sup.2+ ions and Fe(II)(L)-NO, N.sub.2O, or a combination thereof, wherein L is a chelating agent; and reducing NO to N.sub.2O or N.sub.2, or reducing N.sub.2O to N.sub.2.

A method of treating pulmonary hypertension in a subject is provided. The method comprises administering a preparation comprising ammonia oxidizing microorganisms to the subject, thereby treating the pulmonary hypertension. Related preparations, kits, and devices are also provided.

The present invention provides an intestinal flora extraction vessel for extracting an intestinal flora from feces, the vessel including: a vessel main body with a first opening portion and a second opening portion formed therein, the vessel main body being configured so as to be deformable; an opening/closing mechanism configured to open/close the first opening portion of the vessel main body; a filter member accommodated in the vessel main body and partitioning the vessel main body into a first region located on the side of the first opening portion and a second region located on the side of the second opening portion, the filter member being configured to filter off the intestinal flora from the feces; and a communication member attached to the second opening portion, and configured to allow the second region to be in communication with the outside of the vessel main body.

A method for enhancing nitrogen removal by denitrification in a horizontal subsurface-flow constructed wetland, which includes three treatment steps of strain acclimation, strain screening and strain pouring. Firstly, the enrichment of aerobic denitrifying bacteria is achieved through acclimation culture, and the denitrification advantages of the strains are improved to obtain acclimated strains; meanwhile in the present technical solution, after obtained, the acclimated strains are screened for multiple times to remove aging strains and some strains incapable of performing denitrification from sludge and obtain strains truly having good denitrification effects as strains to be poured; and finally the strains to be poured as obtained by the screening is combined with a biocarrier to obtain an immobilized filler and thus prevent the strains from loss.
