For example, the 'kit' developed by Global Ocean Acidification Observing Network (GOA-ON), the Ocean Foundation, the International Atomic Energy Agency (IAEA), and the Ocean Acidification International Coordination Centre (OA-ICC) includes inexpensive pH-stat
systems allowing manipulation of the pH in a wide range of experimental systems from small aquariums to large-scale mesocosms (e.g.
The pH-stat in vitro method has been widely used in the evaluation of the nutritional quality of raw materials and processed feeds, because it is simple, fast, and with high reproducibility (Moyano et al., 2014).
This research contributes to the knowledge of the protein in vitro digestibility, by using the pH-stat method, of protein from animal, vegetal and microbial origin, with actual or potential for inclusion in feeds for M.
In vitro PH-STAT DIGESTIBILITY OF PROTEIN INGREDIENTS IN THE MAYAN CICHLID Cichlasoma urophthalmus
Alarcon FJ, Moyano JF, Diaz M (2002) Evaluation of different protein sources for aqua feeds by an optimized pH-stat system.
This mechanism appears to maintain cerebral blood flow and better cerebral oxygenation during hypothermia and has been given the name pH-stat regulation.
However, with pH-stat regulation, the change in ventilation or the addition of [co.sub.2] results in a respiratory acidosis.
The TitraLab workstations from Radiometer Analytical, Loveland, Colo., are customized for end point, inflection point, pH-Stat
or Karl Fischer titrations.
Evaluation of different protein sources for aquafeeds by an optimized pH-stat system.
Species specific in vitro protein digestion (pH-stat) for fish: method development and application for juvenile rainbow trout (Oncorhynchus mykiss), cobia (Rachycentron canadum), and Nile tilapia (Oreochromis niloticus).
However, with pH-stat regulation, the change in ventilation or the addition of CO2 results in a respiratory acidosis.
Advocates of the pH-stat method argue that since hemoglobin's affinity for oxygen increases as temperature decreases the addition of CO2 or decrease in ventilation (resulting in a respiratory acidosis) during this method will counter the left shift and therefore oxygen release at the tissues will be improved.
