Galoalkalofil'nye geterotrofnye denitrifikatory

Denitrifitsiruyushchie mikroorganizmy yavlyayutsya vazhneyshim zvenom v funktsionirovanii lyuboy ekosistemy. Dannaya monografiya kasaetsya taksonomii i fiziologo-biokhimicheskikh osobennostey galoalkalofil'nykh geterotrofnykh denitrifikatorov, a takzhe osobennostey osmoadaptatsii etikh organizmov v sravnenii s taksonomicheski i metabolicheski otlichnymi ot nikh obitatelyami sodovykh ozer. Rassmotreny osobennosti tsikla azota v sodovykh vodoemakh. Pokazany shirokie adaptatsionnye vozmozhnosti galoalkalofil'nykh denitrifitsiruyushchikh bakteriy roda Halomonas i ikh vazhnaya i mnogoobraznaya rol' v funktsionirovanii alkalofil'nogo mikrobnogo soobshchestva. Vydelena i okharakterizovana "al'ternativnaya" (bezmolibdenovaya) nitratreduktaza, obladayushchaya ryadom neobychnykh svoystv. Prodemonstrirovana rasprostranennost' takikh nitratreduktaz u galoalkalofil'nykh galomonad, chto podtverzhdaet gipotezu o tselesoobraznosti poiska bezmolibdenovykh nitratreduktaz u ekstremofilov. V sravnitel'nom aspekte issledovany osobennosti osmoadaptatsii organizmov, ispytyvayushchikh osmoticheskiy stress v usloviyakh vysokoy karbonatnoy shchelochnosti. Vpervye prodemonstrirovana obshchnost' adaptatsionnykh protsessov u neytrofil'nykh i alkalofil'nykh galofilov.
