The research activities are related to Environmental Microbiology and Biotechnology and the valorisation of agro-food by-products and surplus into fine chemicals.

The ongoing projects are related to:

  • Enrichment and isolation, from contaminated marine sediments, of bacteria with multiple dehalogenating capabilities (PCBs, chlorinated dioxins, chlorophenols, chlorobenzes, chlorinated solvents) and identification of the reductive dehalogenases involved in the dechlorination of different organohalides (H2020 project INMARE);
  • Development and optimization of bioelectrochemical processes for the bioremediation of marine sediments contaminated by PCBs and other organohalides through the sequential stimulation of the reductive dehalogenation and oxidative degradation of the pollutant (H2020 project ELECTRA);
  • Characterization of the colonization dynamics of microplastics by marine microbial communities and of their biodegradation capabilities towards (chlorinated) organic pollutants sorbed on microplastics (JPI-Oceans project PLASTOX);
  • Development of facultative canalized lagoons for the treatment of drainage waters in the Nile river delta region to obtain irrigation-quality water (H2020 project MADFORWATER);
  • Valorization of wheat bran with the production of ferulic acid (to be employed as precursor for monomers production or as antimicrobial and antioxidant additive for polymers) using thermal pre-treatment and enzymatic digestion (H2020 project Agrimax);
  • Development of enzyme-containing biodegradable adhesives for the production of recyclable multi-layer plastic packaging (H2020 project TERMINUS);

  • Development of innovative bioelectrochemical processes for the functionalization of volatile fatty acids and their bioconversion into monomers for the production of biobased polymers (H2020 project NoAW);
  • Development and optimization of a biotechnological process for the fermentative production of 2,3-butanediol from agroindustrial wastes with non pathogenic Bacillus sp. (ALBE project – Italian Green Chemistry Cluster);
  • Characterization of the microbial communities involved in biotechnological processes of environmental and industrial interest (valorisation of agro-industrial wastes into biogas and biopolymers; wastewater treatment in sequencing batch reactors for the production of microbial polymers; aerobic treatment of ground waters contaminated by chlorinated solvents in biofilm packed bed reactors and in bioelectrochemical systems).
