There are still a large variety of microorganisms among aquatic animals, especially probiotic lactic acid bacteria in cold water fishes at high latitudes have not been fully developed. Hence, the present study aims to evaluate potential cold-adapted Lactobacillus strains isolated from intestinal tract (Xinjiang) and select candidates be used as new food preservative agents and/or additives feeding aquaculture.A total 43 spp. were 16 kinds cold-water fishes. They characterized by phenotypic...
Chaos wavelength division multiplexing is a key technology to solve incompatibility between chaos secure communication and large capacity fiber data transmission. However, the existing integrated chaotic semiconductor laser can not achieve tuning in range. Here, wavelength-tunable chip has been designed fabricated. The consists of gain section, distributed Bragg reflector (DBR) grating optical amplifier (SOA) phase section. With feedback from reflective facet mode-beating composite cavities,...
