in microalgae. On the contrary, cyanobacteria Synechocystis harbors gene coding
for dioxygenase involved in polycyclic aromatic hydrocarbons degradation
(Goñi-Urriza and Duran 2018), suggesting a specific function in the aerobic
biodegradation processes.
7.6 Needs
– Further investigation on the phycosphere developed in marine oil-polluted areas
should be carried out by means of -omic approaches in order to interpret the
organization of microbial communities inhabiting the phycosphere, the interaction between the consortium members, their diversity and their function
– The use of engineering systems, as modular microcosms, to investigate the
influence of chemical-physical parameters (in combination with oil) on the
bacterial community succession within the phycosphere
– Further studies to comprehend mechanism(s) that defines microbiome–algae
associations and mode of interexchange occurring during biodegradation processes, also coupling ecogenomics and analytical chemistry
– Specific efforts toward the isolation and identification of novel hydrocarbondegrading bacteria inhabiting the phycosphere
– Well-designed experiments with environmentally appropriate model systems in
simple biological condition (one-to-one species)
– Monitoring natural environment with selective molecular targets with both taxonomical and functional significance in oil-polluted environment
