I Cianobatteri sono un gruppo molto differenziato ed eterogeneo di procarioti capaci di svolgere la fotosintesi ossigenica, un processo fondamentale per l'atmosfera e la vita terrestre. L'interesse biotecnologico verso questi microrganismi è in costante crescita, in particolare per la produzione di biocarburanti, nella bioremediation e nell'agricoltura sostenibile. Un'altra interessante applicazione, molto innovativa, è rappresentata dai sistemi bio-fotovoltaici, i quali sfruttano i cianobatteri come fonte di elettroni e protoni, per generare energia. Questi sistemi presentano numerosi vantaggi, tra cui soprattutto l'utilizzo diretto della luce solare, evitando così combustibili fossili e un elevato impatto ambientale. Inoltre, essi hanno la capacità di generare corrente anche di notte, sfruttando le riserve endogene accumulate dai fotorofi durante la fotosintesi. L'ottimizzazione della loro efficienza e durata è al centro di numerose ricerche, al fine di renderli al più presto una risorsa energetica competitiva, almeno su piccola scala.

Abstract
Cyanobacteria are a highly diverse and heterogeneous group of prokaryotes capable of performing oxygenic photosynthesis, a process fundamental to the atmosphere and terrestrial life. Biotechnological interest in these microorganisms is steadily growing, particularly for the production of biofuels, in bioremediation, and in sustainable agriculture. Another very innovative application is represented by bio-photovoltaic systems, which exploit cyanobacteria as a source of electrons and protons to generate energy. These systems offer numerous advantages, most notably the direct use of sunlight, thus avoiding fossil fuels and a high environmental impact. In addition, they are able to generate electricity even at night, by exploiting the endogenous reserves accumulated by phototrophs during photosynthesis. The optimization of their efficiency and durability is at the center of extensive research, with the goal of making them a competitive energy resource as soon as possible, at least on a small scale.| File | Dimensione | Formato | |
