Биопленки служат для многих бактерий физическим барьером от токсичных соединений и защитой от неблагоприятных условий окружающей среды. Кроме того, для клубеньковых бактерий (ризобий) биопленкообразование является фактором, определяющим конкурентоспособность штаммов ризобий в почвенных условиях. В этом процессе немаловажную роль играют экзополисахариды (ЭПС), биосинтез и функции которых для Rhizobium leguminosarum на сегодняшний день изучены недостаточно, в отличие, например, от Sinorhizobium meliloti. В данной статье рассмотрена основная информация о структуре и биосинтезе ЭПС у R. leguminosarum, описываются основные функции ЭПС, а также эксперименты с генами, связанными с синтезом ЭПС, с целью модификации биопленкообразования, в том числе для целей биотехнологии.
