Provided are CadA polypeptides with mutations that increase activity in alkaline pH compared to the wild-type lysine decarboxylase. Methods of generating such mutant polypeptides, microorganisms genetically modified to over-express the mutant polypeptides, and methods of generating such microorganisms are also provided.

The invention is suitable for the field of panoramic images, and provides a color correction method of the panoramic image, a device thereof and electronic equipment. The method comprises the steps ofacquiring a first fisheye image and a second fisheye image; respectively expanding the first fisheye image and the second fisheye image for obtaining a first image and a second image of an RGB colorspace; calculating overlapping areas between the images; converting the first image and the second image from the RGB color space to a Lab color space; in the Lab color space, adjusting brightness ofthe first image and brightness of the second image; converting the first image and the second image from the Lab color space to the RGB color space; according to the mean color value of a first overlapping area and the mean color value of a second overlapping area, adjusting the color value of the second image through using the first image as a reference, or adjusting the color value of the firstimage through using the second image as a reference. Obviously, the color correction method, the device thereof and the electronic equipment can realize smoother transition of the spliced panoramic image and higher vividness in view.

The invention relates to a beauty product of a Chinese medicament scar-dispelling repair cream and a method for preparing the same. The formula of the beauty product is mainly characterized by comprising the following Chinese medicaments and cosmetic substrates: 6 to 40 grams of rhubarb, 1 to 8 grams of pangolin scales, 1 to 15 grams of saffron, 6 to 40 grams of immature bitter orange, 5 to 35 grams of dragon's blood, 6 to 40 grams of zedoary, 6 to 40 grams of Szechuan lovage rhizome, 6 to 40 grams of sanchi, 3 to 20 grams of ground beetle, 1 to 12 centipedes, 1 to 10 grams of borneol and the like. The preparation method is characterized by comprising the following steps of: (1) weighing up the rhubarb, the immature bitter orange, the zedoary, the Szechuan lovage rhizome and the sanchi in a weight ratio specified in the formula, adding distilled water in an amount which is 6 to 8 times of the total weight of the raw materials into the raw materials to boil he raw materials for 90 minutes for three times, , filtering the mixed solution, mixing filtrates, distillation-condensing the mixed filtrate to 50mL to obtain a water phase for being used later; (2) weighing the Chinese medicaments of the pangolin scales, the saffron, the ground beetles, the centipedes and the like in a weigh ratio in the formula and grinding, filtering the raw materials by a 80-mesh screen, and obtaining the products for being used later; and (3) dissolving the dragon's blood by 10 percent butylene glycol, adding substrates in certain quantity to make the dragon's blood dissolved so as to obtain an oil phase, heating the water phase to the temperature of nearly 90 DEG C, adding the oil phase homogenate to the water phase while stirring, after even emulsification, cooling the mixed solution to the temperature of 50 DEG C, adding the mixed powder obtained at the step(2), evenly stirring the mixed solution, adding the borneol and evenly stirring, and obtaining the finished product.
