Provided are: a microorganism harvesting and oil production method using a nanoclay such as Al-APTES, Ca-APTES, Mg-APTES, Fe-APTES, Mn-APTES or Cu-APTES starting from an oil-containing microorganism; and a method for making oil and biodiesel from an oil-containing microorganism following a biodiesel production method involving esterification and transesterification reactions with an alcohol in the presence of an acidic or basic catalyst starting from extracted microorganism-derived oil. With effective cohesion of microbes, oil can be extracted from microbes in a state where there is a water fraction by using the Al-APTES, Ca-APTES, Mg-APTES, Fe-APTES, Mn-APTES or Cu-APTES as the nanoclay. The oil extracted from the microorganism containing the nanoclay can be converted to biodiesel via the esterification and transesterification reactions using the alcohol in the presence of the acidic or basic catalyst, and the problem of elevated processing costs is alleviated in microalgal harvesting ...

The present invention relates to a method for producing biodiesel in microalgae. The method comprises: a first step of proliferating and culturing microalgae for a predetermined period of time; a second step of converting polar lipid coupled with a cell membrane into a triglyceride type by applying pressure stress to microalgae for a predetermined period of time separately from the first step; a third step of converting biodiesel from triglyceride. According to the present invention, since a large quantity of lipid droplets (LDs) containing triglyceride can be accumulated, costs consumed in extracting oil in overall steps for producing biodiesel can be remarkably reduced. Accordingly, biodiesel can be produced from microalgae at low costs and in an industrially applicable scale. COPYRIGHT KIPO 2017 ...

The present invention relates to a method for enhancing the efficiency in hydrogen production in a biological aqueous gas conversion reaction using a mixing reactor. The method is to effectively accelerate the substance transfer rate, which is a critical issue in conventional gas fermentation while being capable of increasing the substance in a stirring process and gas solubility through a pressurization process for increasing the pressure in the reactor. By increasing the pressure of the reactor having a predetermined stirring speed, the method can increase the solubility of the gas in a liquid reaction product by increasing the pressure in the reactor. Accordingly, the method can enhance the substance transfer efficiency without increasing the stirring speed additionally, reduce the power cost in accordance with the reactor operations, and increase the efficiency in the hydrogen production through the aqueous gas conversion reaction by enhancing the gas-liquid substance transfer efficiency ...
