Abstract: Processes, systems and microorganisms are described herein for producing glycolate from ethylene glycol. The processes generally comprise supplying a fermentation broth into a fermentation vessel, wherein the fermentation broth comprises ethylene glycol and a microorganism having a functional metabolic pathway for utilizing ethylene glycol as a carbon source. In a growth phase, an oxygen-containing gas is injected into the fermentation broth to provide oxygen bio-availability conditions to promote cell growth of the microorganism and limit accumulation of glycolate in the fermentation broth. In a production phase, an oxygen-containing gas is injected into the fermentation broth to provide oxygen bio-availability conditions to promote production of glycolate from ethylene glycol by the microorganism and accumulation of the glycolate in the fermentation broth, to produce a glycolate enriched broth.

Abstract: A compliant tactile sensor may include sponge-like material, a flexible skin, and a fluid pressure sensor. The flexible skin may have a shape, absorb fluid, compress in response to force applied to the sponge-like material, and decompress and return to its original shape when the force is removed. The flexible skin may cover an outer surface of the sponge-like material. The fluid pressure sensor may sense changes in pressure in fluid that is within the sponge-like material caused by a force applied to the flexible skin. A robotic system may include a movable robotic arm, a compliant tactile sensor on the movable robotic arm that senses contact between the compliant tactile sensor and an object during movement of the movable robotic arm and that cushions the effect of that contact, and a reflex system that causes the moveable robotic arm to move in response to commands.
