The selection and adaptation of activated sludge inoculum through successive transfers in batch conditions were performed successfully and continued unhindered for several months.
On the other hand, anaerobic sludge (both, heat pretreated and not) exhibited inactivation after a few transfers in batch conditions, probably due to the presence of high concentration of lipidic compounds.
Lactate dehydrogenase (Ldh) and phosphotransacetylase (Pta) genes were deleted and the Δhpt Δldh Δpta mutant strain was transferred in batch culture for 2,000 hours and a stable strain was achieved [ 19].
As can be seen in Figure 6, repeated transfers in batch conditions with the hexane-treated crude glycerol led to high substrate degradation efficiency and the MMC was never inactivated, showing glycerol fermentation performances comparable with those obtained with activated sludge.
High gas pressure also influences the mass transfer in certain batch processes, although the presence of impurities in the gas would impede the process.
This might sound slow compared with rival technologies, but it is in fact very fast because the page-based approach means that rather than being written and read bit by bit, information is transferred in batches of around a million bits at a time, says Lisa Dhar of InPhase.
In the case of IP lookup studied in this work, the IP addresses are stored in the host memory and are transferred in batches through the PCIe channel to the Intel Phi for processing.
Upon emergence, neonate larvae were transferred in batches of 20 to Petri dishes of artificial diet (a modification of Rogers et al. (2002) as described by Romo et al. (2015)) and reared at 20 ± 1.5 °C until treatment.
Let the soup cool for a few minutes, then transfer it in batches to a blender — removing the center lid and placing a dish towel over the opening to contain splash-ups — and puree until extremely smooth.
In this work, the sunflower oil ethanolysis was performed in a micro-scaled continuous device, inducing better control for heat and mass transfer in comparison with batch processes.
