The present invention relates to a process for treating an oil comprising a chlorophyll substrate, the process comprising contacting the oil with a polypeptide having decolorase activity or a composition comprising the polypeptide, wherein the polypeptide is selected from the group consisting of: a. a polypeptide which has at least 80% identity to amino acids 1 to 318 of SEQ ID NO: 1; and, b. a polypeptide encoded by a nucleic acid sequence that has at least 80% identity to the nucleic acid sequence of SEQ ID NO: 2.

Recombinant microorganisms and methods for using the same are disclosed herein for producing biomass or at least one biomolecule. These methods comprise culturing a photosynthetic microorganism that can overexpress a chlorophyllase, and optionally isolating biomass and/or at least one biomolecule from the culture.

The present invention relates to a process for treating an oil comprising a chlorophyll substrate, the process comprising contacting the oil with a polypeptide having decolorase activity or a composition comprising the polypeptide, wherein the polypeptide is selected from the group consisting of: a. a polypeptide which has at least 80% identity to amino acids 1 to 318 of SEQ ID NO: 1; and, b. a polypeptide encoded by a nucleic acid sequence that has at least 80% identity to the nucleic acid sequence of SEQ ID NO: 2.

The present invention relates to a process for treating an oil comprising a chlorophyll substrate, the process comprising contacting the oil with a polypeptide having decolorase activity or a composition comprising the polypeptide, wherein the polypeptide is selected from the group consisting of: a. a polypeptide which has at least 80% identity to amino acids 1 to 318 of SEQ ID NO: 1; and, b. a polypeptide encoded by a nucleic acid sequence that has at least 80% identity to the nucleic acid sequence of SEQ ID NO: 2.

The present invention relates to a process for treating an oil comprising a chlorophyll derivative. In particular, the present disclosure relates to an improved process for removing impurities, including chlorophyll derivatives and/or trace metals, from an oil using an adsorbent comprising a silica treated with an alkali earth metal oxide, such as magnesium oxide. The process comprises contacting the oil with the adsorbent, wherein the pH of the silica is about 7 or greater, including from about 7 to about 10. The process may further comprise contacting the oil with a polypeptide having decolorase activity or a composition comprising the polypeptide, prior to contact with the adsorbent.
