Abstract:
A tracer particle is provided. The tracer particle includes: a core structure; a nucleic acid molecule immobilized on the core structure; and a shell layer covering the core structure and the nucleic acid molecule; wherein the core structure has a first porosity, the shell layer has a second porosity, and the first porosity is greater than the second porosity.
Abstract:
The disclosure provides a culturing medium for culturing a bacterium of genus Tepidimonas, including: a carbon source which is an organic acid, selected from a group consisting of acetate, lactate and butyrate; a nitrogen source selected from a group consisting of ammonium sulfate ((NH4)2SO4), ammonium nitrate (NH4NO3), ammonium chloride (NH4Cl) and urea; phosphate; magnesium chloride (MgCl2); yeast extract; and trace elements.
Abstract:
A biological hair shape change composition including a macromolecular component, a small molecular component and an alkali agent component is provided. The macromolecular component includes a protease belonging to the class of alkaline proteases, and the small molecular component includes a peptide with reduction activity. Both the macromolecular component and the small molecular component are obtained from a fermentation product of Bacillus licheniformis and a keratin and/or keratin polymer-containing medium. Molecular weights of ingredients in the macromolecular component are greater than or equal to 3 kDa and are 3-1000 kDa, and molecular weights of ingredients in the small molecular component are less than 3 kDa and are 0.01-2.99 kDa.
Abstract:
The disclosure provides a method for producing extracellular proteins from genus Tepidimonas, including: performing a fermentation culturing to a bacteria of genus Tepidimonas with a culturing medium to form a fermented liquid, wherein the composition of the culturing medium includes a carbon source which is an organic acid, selected from a group consisting of acetate, lactate and butyrate; a nitrogen source selected from a group consisting of (NH4)2SO4, NH4NO3, NH4Cl and urea; phosphate; carbonate; MgCl2; yeast extract; and trace elements, and wherein the gas feeding rate for the fermentation culturing is about 0-0.1 vvm; and after the fermentation culturing is completed, collecting the fermented liquid, wherein the fermented liquid contains extracellular protein secreted from the bacteria of genus Tepidimonas.
