A dyeing method includes immersing a fiber into a dye for dyeing the fiber, in which the dye includes indigo and indirubin, and the indigo and the indirubin have a weight ratio of 20:1 to 80:1. The indigo in the dye has a concentration of 0.1% o.w.f. to 5% o.w.f. The dyed fiber may simultaneously have high luminance, high color saturation, high strength of colorization, and sufficient colorfastness.

Dye for fiber and dyeing method

The disclosure provides a dyeing method using bio-dye. A first compound containing an X group is reacted with a second compound containing a Y group to form a third compound, in which the X group is selected from the group consisting of an isocyanate group, a carbodiimide group, an aziridinyl group and an epoxy group, the Y group is selected from the group consisting of a hydroxyl group and an amine group, and the second compound is an amine compound and contains two or more Y groups. Cationization of the third compound is carried out with a fourth compound containing a carboxyl group to form a cationic modification agent. A cationic modification treatment is performed on a fiber material by using the cationic modification agent to form a cationized fiber material. Thereafter, a dyeing treatment is performed on the cationized fiber material through a dye solution containing bio-dye to color the cationized fiber material.

A genetically modified microorganism includes: an exogenous nucleic acid sequence encoding naphthalene dioxygenase (NDO), wherein the endogenous icd gene of the genetically modified microorganism is knocked out, in which the endogenous icd gene encodes isocitrate dehydrogenase (IDH), and wherein the genetically modified microorganism is capable of using glutamic acid and/or a salt thereof as a nitrogen source to grow and producing indigo dye.

Genetically modified microorganism and method for producing indigo dye

A convective polymerase chain reaction apparatus includes a tube, a temperature control unit, at least one light source and a sensor. The tube includes a cavity used to contain a reaction solution. The reaction solution has a liquid level measured from a bottom of the cavity to a top surface of the reaction solution. The temperature control unit is disposed adjacent to the tube for controlling the temperature of the reaction solution. The at least one light source provides a light beam passing through an incident portion of the tube to excite the reaction solution emitting a fluorescent light. The incident portion is located at a height greater than &#xbd; of a liquid level. The sensor is adjacent to the tube for detecting the excited fluorescence. The light beam has an incident direction forming a non-straight angle with a long axis of the tube.
