Disclosed herein are methods of producing aqueous dispersions comprising insoluble alpha-glucan having at least 50% alpha-1,3 glycosidic linkages. For example, in addition to dispersing insoluble alpha-glucan that has never been dried, methods are disclosed for effectively dispersing insoluble alpha-glucan that has previously been dried. Further disclosed are aqueous dispersions comprising insoluble alpha-glucan, such as those produced by the disclosed methods. Aqueous dispersions of the present disclosure have enhanced features of viscosity, stability, and particle size distribution, for example. Application of aqueous dispersions in various products and uses are also disclosed.

A method is described to produce cellulose sheets and suspensions by fermenting biomass obtained from household and/or industrial waste. The inoculum in the fermentation includes cellulose producing bacteria and optionally yeast cells. The method has a high cellulose productivity. The resulting sheets or suspensions can be used to produce various further materials, such as disposable vessels, sachets, artificial leather. The sheet and suspensions can be used as additives in material production, such as paper making production. The method provides an alternative to make disposable items that are currently made of plastic, and textiles.

A conjugation device includes at least one flow reactor having an inlet and an outlet, the flow reactor(s) being completely filled with a support such as a matrix including 1) chromatography beads, fibers or membranes, and 2) a biologic catalyzer, namely the enzyme ligase, which is immobilized onto this support; a fluid delivery unit in fluid communication with the inlet of the flow reactor(s) and configured to continuously provide the flow reactor(s) with at least one kind of reaction fluid such as antibody and linker-payload according to stages of the conjugation process, the at least one kind of process fluid including a first moiety and a second moiety of a conjugate to be produced; and a fluid collection unit in fluid communication with the outlet of the flow reactor(s) and configured to control collection of fluid flowing out of the outlet of the flow reactor(s) according to the stages of the conjugation process. In a period of enabling the at least one kind of reaction fluid to continuously flow through the flow reactor(s), a conjugation reaction is conducted between the first moiety and the second moiety under catalysis of the ligase to produce the conjugate.

Methods and systems are described herein for manufacturing oligosaccharides, including maltosyl-isomaltooligosaccharides. The methods involve removing undesired components from fermentation fluids that contain maltosyl-isomaltooligosaccharides.
