Abstract: Elastomer-based soft-robotic micro-tentacles capable of winding around and holding microscale objects and methods of fabricating same are provided. To realize the thin, highly deformable microtubes, a fabrication technique based on in situ thermal solidification of PDMS dip-coated around a cylindrical template and direct peeling of the cured structure is presented. This process is capable to asymmetrize the microtube's cross-sectional shape and enable the microtube to bend up to a single turn. To amplify the bending into a life-like, multi-turn spiraling motion, a semi-analytical model to shape-engineer the microtube and turn it into a micro-tentacle was produced. As a result, a hump is added to the microtube to enable the multi-turn spiraling motion.

Abstract: The present invention provides a fed-batch culture method comprising a step of fed-batch-feeding a carbon source base and a base in such a manner that the pH level can be maintained at a level suitable for the growth of microorganisms for fermentation of a carbon source. The present invention also provides a method for preparing organic acids using the fed-batch culture method. The present invention fed-batch-feeds a neutralizing agent such as ammonium bicarbonate, ammonium carbonate or alkali metal-containing weak base, and a carbon source substrate in preparing organic acids by microorganism fermentation. Thus, a pH level suitable for the survival of microorganisms for carbon source fermentation can be maintained, and the speed of injecting the carbon source base which is the source material can be appropriately adjusted.
