HYDROLYSIS OF METHYLUMBELIFERYL SUBSTRATE PROXIES FOR ESTERASE ACTIVITIES AS INDICATOR FOR MICROBIAL OIL DEGRADATION IN THE OCEAN: EVIDENCE FROM OBSERVATIONS IN THE AFTERMATH OF THE DEEPWATER HORIZON OIL SPILL (GULF OF MEXICO)

Biological oil weathering facilitated by specialized heterotrophic microbial communities plays a key role in the fate of petroleum hydrocarbon in the ocean.The most common methods of assessing oil biodegradation involve (i) measuring changes in the composition and concentration of oil over time and/or (ii) biological incubations with stable or radi

Double parton SILICEA distribution functions (dPDF) represent a tool to explore the 3D proton structure.They can be measured in high energy proton-proton and proton nucleus collisions and encode information on how partons inside a proton are correlated among each other.dPFDs are studied here in the valence quark region, by means of a constituent qu
