Project: Biochemical, enzymologic, and genetic factors involved in forming postmortem melanin in shrimp
Shrimp without and with melanosis Principal Researcher: Dr. Julio Humberto Córdova Murueta
Participant(s): Dr. Norma Yolanda Hernández Saavedra , Dr. Fernando Luis García Carreño

Melanin is a substance that produces a dark color called melanosis (spots), and which affects some products for human consumption, such as shrimp. In these organisms, melanosis is detrimental to their appearance, affecting consumers’ preference. However, this pigment is produced by an enzyme called phenol oxidase, and it DOES NOT affect humans who eat organisms with melanosis.  Because there is a limit in using products against melanosis in shrimp and in other organisms, it is necessary to know the phenomenon to find alternatives that retard or reduce melanosis ...

Project: Interaction between antemortem physiology and postmortem biochemical processes in the white shrimp (Litopenaeus vannamei) muscle and its impact in quality, technological interrelation, and shelf life
  Principal Researcher: Dr. Fernando Luis García Carreño
Shrimp

One of the problems of marketing fresh-whole shrimp is the development of dark spots on the shrimp’s body caused by melanin, the same pigment in hair. The process is called melanization. The reason for our interest in studying this process is to eventually find ways to avoid and decrease melanization and thus extennd shelf life of this important sea product ...

Project: Transcriptome of the white shrimp (Litopenaeus vannamei): gene expression differences between hepatopancreas and branchiae
Shrimp shedding Principal Researcher: Dr. Fernando Luis García Carreño
Participant(s): María de los Angeles Navarrete del Toro

Through this project we hope to obtain better knowledge on the phenomena that occur during the shedding cycle in shrimp. It is thus important to know the participants in this cycle, such as chitin synthase and chitinase enzymes, as well as the genes that modify them. This knowledge will allow us to understand and eventually modify them for human benefit...
