In this study,different microbial strains,as single and mixed-cultures,were used to ferment the pate olive cake(POC),a by-product of olive oil *** particular,strains belonging to Candida boidinii,Wickerhamomyces anomalus and Lactiplantibacillus plantarum were *** fermentation was carried out on diluted(3:2)POC without and with glucose(2%w/v)***,phenolic compounds were monitored during fermentation in POC added with glucose differetly inoculated and the microbial community,at the end of fermentation,was evaluated by Next Generation Sequencing(NGS)*** highlighted that inoculated samples showed an hydroxytyrosol content higher than the un-inoculated *** particular,during fermentation the sample inoculated with ***,both in single and in mixed culture together with ***,increased the hydroxytyrosol content by 275 and 261 mg/L,respectively,after 8 days,to reach the highest content at the end of *** analysis revealed a low abundance of 16S ribosomal RNA genes and fungal ITS in all samples at any sampling ***,at the end of fermentation,all samples exhibited a different bacterial community with a decrease in acetic acid bacteria and an increase in Lactobacillaceae ***,no effect was detected in any samples on fungal metagenomic profile,where Dipodascus geotrichum was found dominant both at initial and final *** conclusion,the present study confirmed that selected cultures can drive the fermentation and have an impact on the phenolic profile.

Increasing continental suspended sediment influx to coral reefs is an example of land-sea coupling that requires the identification of sources,magnitude of transport,and controlling *** Brazil,a small coastal basin(Macae River) was identified as a source of suspended sediment to a coral reef on the coast of Cape Armacao dos *** suspended sediment loads were measured at the basin as were fluxes within the estuary and towards the coast during eight tidal *** load and yield from this basin were typical of small coastal basins,showing high to moderate slopes and transitional land ***,the magnitude of the river loads was lower than the sediment transport within the estuary,indicating that the estuary amplifies river fluxes and sustains the transference of suspended sediment alongshore to the coral ***,the estuary displays both suspended particle retention and export capacity and,therefore,fluxes to the coast and the coral reef occur as episodic events.
