Interessi

***Principali ambiti di ricerca

Ha esperienza nella ricerca sull'uso di microrganismi fototrofi, anche in integrazione con microrganismi eterotrofi, per la produzione di specifici prodotti (principalmente idrogeno, ma anche carotenoidi e liposomi) da substrati derivati da scarti agroindustriali.

Studia inoltre il ruolo delle sostanze polimeriche extracellulari secrete dalla biomassa microbica fototrofa (cianobatteri e microalghe) nella formazione e stabilizzazione delle croste biologiche del suolo, che sono comunità microbiche complesse. In particolare, si è recentemente concentrata sulla capacità di trattenere l'acqua della matrice polimerica e sulla composizione delle sue componenti polisaccaridiche.

Ha iniziato di recente a studiare le interazioni metaboliche che si verificano tra microrganismi fototrofi ed eterotrofi in condizioni di laboratorio artificiali.

***Temi per Tesi di Laurea Triennale e Magistrale

Produzione fotobiologica di idrogeno con batteri fototrofi non sulfurei: studi sull'ottimizzazione della produzione di idrogeno in diverse condizioni di luce e su sistemi integrati per la produzione di idrogeno basati su fermentazione al buio e fotofermentazione.
Cianobatteri e microalghe produttrici di esopolisaccaridi: studi fisiologici e ricerche sul possibile sfruttamento dei polimeri prodotti.
Ecofisiologia di microrganismi fototrofi produttori di esosaccaridi in condizioni di stress: studi sulla distribuzione e sul ruolo di questi microrganismi negli ambienti naturali, in particolare nelle croste biologiche del suolo in aree desertiche e degradate.
Fisiologia e coltivazione delle diatomee marine e loro interazione con i batteri marini.

Alessandra ADESSI

Interest

***Main research topics

She has research experience in the use of phototrophic microorganisms, also in integration with heterotrophic microorganisms, for the production of specific products (mainly hydrogen, but also carotenoids and liposomes) from agroindustrial waste derived substrates.

She also studies the role of the extracellular polymeric substances, secreted by the phototrophic microbial biomass (cyanobacteria and microalgae) in the formation and stabilization of biological soil crusts, which are complex microbial-based communities. In particular, she recently focused on the water-holding capacity of the polymeric matrix, and the composition of the polysaccharidic components.

She recently begun to study the metabolic interactions occuring between phototrophic and heterotrophic microbes in artificial laboratory conditions.

*** Topics for Bachelor and Master Thesis:

- Photobiological hydrogen production with purple non sulfur bacteria: studies on the optimization of hydrogen production under various light conditions and studies on integrated systems for hydrogen production based on sequential dark and photofermentation.

- Exopolysaccharide-producing cyanobacteria and microalgae: physiological studies and studies on the possible exploitation of the polymers produced

- Ecophysiology of exopolysaccharide-producing phototrophic microorganisms under stress conditions: studies on the distribution and on the role of these microorganisms in natural environments, in particular in Biological soil crusts in desert and degraded areas.

- Physiology and cultivation of marine diatoms and their interaction with marine bacteria.
