“Oily Waste Water Treatment Using Microalgae”
The Malaysian palm oil industry has grown rapidly. But, this industry has the problem of the enormous generation of oily wastewater from palm oil refining plant. Eco-friendly treatment methods of this wastewater are wanted, and algae biomass should be useful for this purpose. But there is no study about oil removal using microalgae. So, objective of this research is confirmation of the effect of microalgae on oil removal from model oily waste water. C. vulgaris was cultivated in tap water in which palm oil was emulsified. The results showed possibility that microalgae could remove oil from waste water.

“Studies on lipid metabolic enzymes, metabolic networks, and lipid fermentation”
Lipid is an important substance group in various industrial fields including food, medicines and fuels. Lipid fermentation by microorganisms can efficiently produce lipid species that are difficult to obtain in large quantities from conventional sources such as plant, fish, and animal lipids. Recently, lipid fermentation from various biomass has attracted attention due to environmental issues. In this presentation, I will introduce the research about functions of enzymes related to lipid biosynthesis and the metabolic network formed by these enzymes for diversification of lipid products and improvement of productivity.

“Phosphorus recovery from palm oil mill effluent (POME) in supercritical water”
The amount of liquid waste from palm oil production in Indonesia is increasing every year as the production capacity increases. Phosphorus in palm oil mill effluent (POME) could be the important potential phosphorus resource, considering the depletion of phosphate rock due to over exploitation. Supercritical water gasification (SCWG) technology could convert POME into valuable gas coming along with phosphorus recovery. To acquire a good understanding about behavior of POME conversion in SCWG, a set of experiments were developed. Here, variation of temperature (500-600°C) and residence time (5-50s) with controlled pressure at 25MPa were employed in a continuous reactor. A reaction model of conversion of organic phosphorus in POME to inorganic phosphorus was also proposed. As the results, the organic phosphor could be converted into inorganic phosphorus and precipitation took place in the reactor. The rate was faster at higher temperature. The reaction followed first order kinetics, and the model was found to fit well with experimental data.

We will hold the discussion meeting from 18:00 (800 JPY needed). Join this meeting, too if you are available.
