“…This can be explained in part by the saturation of digestive enzyme activity. The results from Chasmagnathus granulatus are in contrast to our results, as the pyruvate kinase level in the jaw muscle of crabs fed a high-CBH diet was 4-fold greater than in crabs fed a highprotein but low-CBH diet (Marqueze et al 2006). In European sea bass and gibel carp, hepatic pyruvate kinase activity increased when fish were fed diets with a high starch content (Enes et al 2006, Tan et al 2009).…”

“…HK and PK are two key enzymes involved in glycolysis, and they play an important role in maintaining the level of blood glucose and the rate of glycolysis (Allert, Ernest, Poliszczak, Opperdoes & Michels, 1991;Sangiao-Alvarellos et al, 2006). SDH is involved in the tricarboxylic acid cycle and oxidative phosphorylation, and its activity can reflect the levels of aerobic metabolism to some extent (Marqueze, Kucharski & Da Silva, 2006). More energy may be needed to resist the high-speed impact of water currents as flow velocity increases.…”

“…The organisms may have obtained the energy required to resist the stress from external environmental factors by enhancing glycolysis. SDH is involved in the tricarboxylic acid cycle and oxidative phosphorylation, and its activity can reflect the levels of aerobic metabolism to some extent (Marqueze, Kucharski & Da Silva, 2006). LDH is involved in anaerobic metabolism and has been regarded as a stress indicator (Albert & Ellington, 1985).…”

To study the effects of different flow velocities on growth, metabolism and nitrogen (N) and phosphorus (P) budget of Haliotis discus hannai Ino in a recirculating aquaculture system, abalones (shell length: 45.71 AE 3.09 mm, body weight: 8.62 AE 0.75 g) were cultured at three different flow velocities with four replicates each: high (400 L/hr), medium (300 L/hr) and low (200 L/hr). At the end of the 70 days experiment, the survival rate, food intake and P utilization rate of abalones in the 200 L/hr group were significantly lower than those in any other group (p < .05), whereas the total ammonia nitrogen and nitrite nitrogen concentrations in the water were significantly higher than those in any other group (p < .05). The body weight specific growth rate, food conversion efficiency, abalone-harvested N and P outputs and N utilization rate were ranked as follows: 300 > 400 > 200 L/hr (p < .05). In the 300 L/hr group, the activities of hexokinase, pyruvate kinase and lactate dehydrogenase were significantly lower than those in the 400 L/hr group, whereas the activity of succinate dehydrogenase was significantly higher than that in the other two groups (p < .05). Aerobic metabolism was the main source of energy acquisition for abalones in the 300 L/hr group. In the 400 L/hr group, the expression levels of manganese superoxide dismutase and thioredoxin peroxidase significantly increased from Day 35 to Day 70, but they still were significantly lower than the values in the 200 L/hr group (p < .05). In the 200 L/hr group, the expression levels of catalase and heat shock protein 70 were significantly higher than those in any other group, and they significantly increased from Day 35 to Day 70 (p < .05). These results indicate that maintaining flow velocity at 300 L/hr will minimize oxidative damage due to deterioration of water quality, reduce the energy consumption required for organisms to resist the impact of water flow, improve the N and P utilization rates of the recirculating aquaculture system, and reduce the cost of culturing abalones.

Abstract:The effects of osthol, a plant coumarin, on morphology, sugar uptake and cell wall components of Fusarium graminearum were examined in vitro by electron microscopy, 14 C-labelling and enzyme activity detection. The results revealed that osthol could inhibit the hypha growth of F. graminearum by decreasing hyphal absorption to reducing sugar. After treatment with 100 μg·mL -1 osthol for 24 h, many hyphal fragments of F. graminearum appeared. Microscopy observation showed that the cell walls of hyphal fragments blurred and the organelles of the cells degraded with the increasing vacuoles. The N-acetyl-D-glucosamine contents and chitinase activity both increased when hypha were treated with 100 µg·mL -1 osthol, whereas the activity of β-1,6-glucanase remained unchanged. When F. graminearum fed with 14 C glucose was treated with 100 μg·mL -1 osthol, glucose contents decreased to the lowest level, while the contents in non-osthol treated controls remained unchanged. These results suggested that chitinase activity might be related to glucose starvation under osthol treatment, and that the appearance of hyphae fragments maybe the results of the promoted chitinase activity which itself triggered chitin degradation.
