PhD project:

Ma­ri­ne po­ly­sac­cha­ri­des are thought to be fast-food for mi­cro­bes. Howe­ver, po­ly­sac­cha­ri­des can also ac­cu­mu­la­te in sea­wa­ter and se­di­ments. We in­ves­ti­ga­te fac­tors that in­flu­ence the re­ac­tivi­ty of po­ly­sac­cha­ri­des and ask whe­ther they can be a sink in the glo­bal car­bon cy­cle.
Our aim is to link po­ly­sac­cha­ri­de struc­tu­re to its tur­no­ver rate by mi­cro­bes. We use de­fi­ned po­ly­sac­cha­ri­des and cul­ti­va­ted iso­la­tes to iden­ti­fy li­mi­ta­ti­ons for fast po­ly­sac­cha­ri­de de­gra­da­ti­on. The abili­ty of mi­cro­bes to di­gest tho­se sub­stra­tes is pro­bed with ge­no­mics, pro­teo­mics, phy­sio­lo­gi­cal ex­pe­ri­ments and en­zy­me as­says in the la­bo­ra­to­ry and in the en­vi­ron­ment.
