We hypothesized that commercial feeds processed at 75 °C or higher would present no risk for EHP transmission, even if they test positive for EHP by PCR. To test this hypothesis, the purified EHP spores (1 × 10⁶ spores) were incubated at 25 °C (non-heated) or 75 °C (heated) for 45–60 s prior to determining v ...

Abstract:
... Microalgae are a source of diverse high-value compounds, such as carotenoids and fatty acids, which have a potential application in aquafeeds. Some microalgae species present complex cell wall structures, which make them poorly digestible, thus limiting their use as a feed ingredient. Consequently, applying extracted compounds to aquafeeds instead of using the whole algal biomass is advantageous a ...

Abstract:
... The increased use of plant ingredients in aquafeeds over the last decades, as replacement for fish meal, has led to rising levels of undesired non-starch polysaccharides (NSP) and phytate. Both NSP and phytate degrading enzymes and probiotics have been widely studied. They can be used as a tool to deal with increasing levels of NSP and phytate in aquafeeds. However, studies combining both probioti ...
