Cefaclor is used for treatment of infections caused by susceptible organisms including H influenzae and for treatment of otitis media, sinusitis, and infections involving the respiratory tract. It may not be appropriate in acute sinusitis, owing to less activity and the potential for severe allergic reactions.
nitrogen-fixing bacteria noun [pl]. âº biology âbacteria that can âabsorb nitrogen from the âair and âchange it into a âform that âplants can use for âfood. (Definition of nitrogen-fixing bacteria from the Cambridge Academic Content Dictionary Â© Cambridge University Press). See all translations.
All organisms use the ammonia (NH3) form of nitrogen to manufacture amino acids, proteins, nucleic acids, and other nitrogen-containing components necessary for life. Biological nitrogen fixation is the process that changes inert N2 into biologically useful NH3. This process is mediated in nature only by N-fixing rhizobia bacteria (Rhizobiaceae, Î±-Proteobacteria) (SÃ¸rensen and Sessitsch, 2007).
