The marine red microalga can simultaneously synthesize long-chain polyunsaturated fatty acids, including eicosapentaenoic acid (C20:5, EPA) and arachidonic acid (C20:4, ARA). However, the distribution and synthesis pathways of EPA and ARA in are not clearly understood. In this study, CCALA 415 was cultured in nitrogen-replete and nitrogen-limited conditions.

A marine red microalga is considered as the potential feedstock for phycoerythrin production. However, the phycoerythrin-related properties of have not been systematically evaluated, especially between the species of and .

In the present study, a novel fractional extraction strategy based on the characteristics of these compounds was established using cold water, 95% ethanol, and hot water. The yield of phycoerythrin, lipids, and polysaccharides was 63.

This study aims to explore risk factors for severe clinical outcomes in children with pneumonia-related bacteremia and evaluate the value of time to first positive blood cultures (TTFP) in predicting prognosis. Children with pneumonia-related bacteremia in Children's Hospital of Chongqing Medical University were included (January 2013-May 2019), respectively.
