An ultramarine fluorescent protein, is a protein selected from (a) and (b) protein: (a) a protein consisting of an amino acid sequence set forth in SEQ ID:NO. 2; (b) a protein derived from (a) by substitution, deletion or addition with one or more amino acids in the amino acid sequence of (a) and having activity of the ultramarine fluorescent protein. The ultramarine fluorescent protein (UFP) has the characteristics of pH-insensitivity and light stability, and its chromophore can absorb long-wavelength ultraviolet (UVA) and release fluorescence at wavelength longer than 400 nm. And the aromatic amino acids residue (with content of 9.2%) can absorb medium wavelength ultraviolet (UVB) and release UVA.

Integrated automatic sea cucumber cooking and soaking system

The disclosure discloses an integrated automatic sea cucumber cooking and soaking system, which belongs to the technical field of sea cucumber processing. The system includes a cabinet body for holding sea cucumbers; the cabinet body is communicated with an external circulating cooling and filtering system and a cold and hot pipe system; the external circulating cooling and filtering system is used for providing cooled filtered circulating water for the cabinet body; the cold and hot pipe system can be used for increasing or decreasing temperature of circulating water in the cabinet body; a top of the cabinet body is provided with a weighing device; the weighing device is connected, through a tension column, to a weighing bracket arranged in the cabinet body; a plurality of groups of supporting holders are arranged on the weighing bracket along a vertical direction; a slotted hole drawer for holding sea cucumbers is arranged on each group of the supporting holder in a supported manner; and the circulating water in the cabinet body is subjected to internal circulation through an internal circulating pipeline arranged outside. According to the disclosure, sea cucumber cooking and soaking processes can be integrated; the cooking and soaking efficiency can be improved; and waste of water is reduced.
