Stickwater, a by-product of the fish meal and oil industry, is an aqueous suspension of fish proteins, lipids, and other materials, and also contains soluble nonprotein nitrogen but not carbohydrate. It is usually partially evaporated by heat to a marketable form called "fish solubles," which is sold with an acid preservative as an animal feed supplement. However, fish solubles are only used to...

Lactate is an important intermediate metabolite in human bioenergetics and is oxidized in many different tissues including the heart, brain, kidney, adipose tissue, liver, and skeletal muscle. The mechanism(s) explaining the metabolism of lactate in these tissues, however, remains unclear. Here, we analyze the ability of skeletal muscle to respire lactate by using an in situ mitochondrial prepa...

Assessing the compatibility of industrial discharges with biological process a municipal wastewater treatment plant (WWTP) may represent critical task. Indeed, either focusing only on chemical characterization or ecotoxicity tests designed to assess impact surface waters lead questionable misleading conclusions. The feasibility an connection sewer should better take into account features downst...

An investigation was made into polymeric films based on polyvinylpyrrolidone (PVP) as the matrix, in combination with synthetic zeolite and dried or pyrolyzed biocarbon (biochar). The were prepared by casting method, their properties variously analysed (optical microscopy, FTIR analysis, differential scanning calorimetry, mechanical properties, water solubility, uptake). Evaluation also encompa...

In this study, the removal of refractory organic pollutants by UV/TiO2/periodate system and effects different process parameters are investigated. The proves good efficient for degradation various recalcitrant pollutants, including Rhodamine B (RhB), 17?-ethynylestradiol (EE2), diclofenac (DFC), sulfamethoxazole (SMX), ciprofloxacin (CIP) carbamazepine (CBZ). combined (IO4-) demonstrates an imp...

The mixotrophic growth with methanol plus thiosulfate was examined in nutrient-limited mixotrophic condition for Methylobacterium goesingense CBMB5 and Methylobacterium fujisawaense CBMB37. Thiosulfate oxidation increased the growth and protein yield in mixotrophic medium that contained 150 mM methanol and 20 mM sodium thiosulfate, at 144 h. Respirometric study revealed that thiosulfate was the...

To assess energetic costs during rest and locomotion in a small insect, we measured metabolic rate in freely moving ants Camponotus sp. (average body mass 11.9 mg). The animals ran in a straight respirometric chamber in which locomotor speed and CO2 release were monitored simultaneously using flow-through respirometry and conventional video analysis. In resting intact ants, standard metabolic r...
