Analyses of phenolic compounds occurring in olive oil mill wastewaters by GC–MS

Phenolic compounds in olive oil mill wastewaters were analysed by HRGC–MS after extracting the acidified solution with ethyl acetate and derivatization with N,O-bis(trimethylsilyl)trifluoroacetamide. Both simple and complex phenols were detected with the latter being the most abundant. 1,2-dihydroxybenzene (catechol), p-hydroxyphenyl ethanol (tyrosol), 3,4-dihydroxyphenyl ethanol (hydroxytyrosol) and 4-hydroxy-3-methoxyphenyl ethanol (homovanillyl alcohol) predominated among the simple phenols using a gas chromatograph coupled with a mass selective detector.

Food quality and season affect gene expression of the mucosal lectin MeML and particle sorting in the blue mussel Mytilus edulis

The blue mussel, Mytilus edulis, is able to use biochemical cues to sort food particles. Recently, a mucosal lectin (MeML) identified in pallial organs of M. edulis was suggested to play a role in the capture and sorting of food particles. The current study presents data obtained in 2010 showing that sorting efficiencies and MeML gene expression in M. edulis increased when mussels were either fed poor quality food or starved. In addition, results suggest that particle capture and degree of selection increased during the spawning period, although the quality of food delivered to mussels before the experiments seemed to have a stronger impact on particle-sorting efficiency. Overall, the impact of both endogenous (physiological status) and exogenous (food quality) factors were shown to affect the expression of MeML in mussel feeding organs, and the food sorting abilities.
