Research interests

I am interested in multidisciplinary research, especially which aims to understand the impact of environmental quality to the food quality and safety. My current research topic covers the interaction between metal e.g. copper and microbial contaminants in water affect to the histamine accumulation in crustacean meat – via changing the microbial community structures – during storage.

Interaction between environmental copper, microbial community structure and histamine levels in edible crustaceans.

Water pollution, particularly metal and microbial, is a global problem. When the pollution occurs in aquaculture areas, it may negatively impact the edible species and eventually threaten food quality and safety. Indonesia, one of the top ten aquaculture producers in the world, also experiences severe water pollution. Aquaculture, especially shrimp, is of great economic important for Indonesia. For that reason, we study the influence of metal pollution and microbial contamination in an edible crustacean species. The metal of interest in this study is copper, referring to the situation found in shrimp ponds along the Semarang cost line, Central Java – Indonesia. The main aim of this project is to determine the interaction between copper and microorganism in the aquatic environment and their impact upon crustaceans. To deal with the problem, several approaches are selected, i.e. metal bioaccumulation, histamine formation in the animal triggered by metal exposure, bacterial community structure under the influence of copper contamination and histamine accumulation in the crustacean’s edible tissue (meat) during storage. In our study, the freshwater marbled crayfish is chosen as a model of edible crustacean, due to its accessibility for biological experiments, i.e. ease of culturing and producing high numbers of genetically identical offspring.
