A heterogeneous catalyst for Fenton reaction was prepared by immobilizing Fe(III) onto
collagen
fiber and its catalytic activity for the photo-assisted decomposition of Malachite Green (MG) was investigated. The results indicated that this Fe(III)-immobilized
collagen
fiber (Fe-CF) can effectively catalyse the decoloration and decomposition/mineralization of MG in aqueous solution. Catalysed by Fe-CF, MG solution was completely decolorized in 30 min, while 55.0% of
TOC
was removed from the dye solution within 120 min in the presence of H(2)O(2) and UVA irradiation (365 nm, 10 W). Fe-CF was recycled for seven times with certain activity loss (32.6% in decoloration, 18.5% in
TOC
removal), and its catalytic activity can be easily recovered by re-immobilization of Fe(III). Therefore, Fe-CF could act as an efficient and cost-effective catalyst for the photo-assisted decomposition of MG, and shows potential applications in practice.

Fish muscle, the main edible parts with high protein level and low fat level, is consumed worldwide. Diet contributes greatly to fish growth performance and muscle quality. In order to elucidate the correlation between diet and muscle quality, the same batch of juvenile grass carp (
Ctenopharyngodon idellus
) were divided into two groups and fed with either grass (
Lolium perenne, Euphrasia pectinata
and
Sorghum sudanense
) or artificial feed, respectively. However, the different two diets didn't result in significant differences in all the detected water quality parameters (e.g., Tm, pH, DO, NH
3
/[Formula: see text]-N, [Formula: see text]-N, [Formula: see text], TN, TP, and
TOC
) between the two experimental groups. After a 4-month culture period, various indexes and expression of myogenic regulatory factor (MRFs) and their related genes were tested. The weight gain of the fish fed with artificial feed (AFG) was nearly 40% higher than the fish fed with grass (GFG). Significantly higher alkaline phosphatase, total cholestrol, high density cholestrol and total protein were detected in GFG as compared to AFG. GFG also showed increased hardness, resilience and shear force in texture profile analysis, with significantly bigger and compact muscle fibers in histologic slices. The fat accumulation was most serious in the abdomen muscle of AFG. Additionally, the expression levels of
MyoG, MyoD, IGF
-
1
, and
MSTNs
were higher, whereas
Myf
-
5, MRF4
, and
IGF
-2 were lower in most positional muscles of GFG as compared to AFG. Overall, these results suggested that feeding grass could promote muscle growth and development by stimulating muscle fiber hypertrophy, as well as significantly enhance the expression of
CoL1A
s. Feeding
C. idellus
with grass could also improve flesh quality by improving muscle characteristics, enhancing the production of
collagen
, meanthile, reducing fat accumulation and moisture in muscle, but at the cost of a slower growth.
