摘要： Muscle quality, antioxidant status, and inflammatory and apoptotic molecule expression were investigated in juvenile largemouth bass fed five levels of Chlorella for 60 days. The results showed that muscle quality can be improved by increasing the muscle crude protein content, muscle and skin brightness value (L*), redness value (a*) and yellowness value (b*) in Chlorella-supplemented diets without affecting the growth and muscle fiber development of fish. Chlorella supplementation did not cause oxidative stress in muscle, but optimal Chlorella administration alleviated the muscle inflammatory response by downregulating the nuclear factor kappa B (NF-kappa B)mediated proinflammatory factors such as interleukin 1 beta (IL-1 beta) and interleukin 8 (IL-8). Moreover, antiapoptotic effects were induced by upregulation of anti-apoptotic genes, such as b cell lymphoma-2 (bcl-2) and myeloid cell leukemia-1 (mcl-1), and downregulation of pro-apoptotic genes, including bcl2-associated x (bax) and caspase3. In conclusion, Chlorella improved muscle quality, alleviated muscle inflammation and resisted muscle apoptosis.
