Media production demands. In recent years there has been a demand for increased efficiency in media production operations and subsequently a large number of demands made on media, which had previously been selected due to its ability to support large-scale culture of cells (Decaria et al. 2009; Hudson 2013; Jerums and Yang 2005).

Several commercial organizations market such a medium. Regardless of how the culture is handled before it is added to milk, presence of antibiotics in milk (as a result of administering them to lactating dairy cows) will either retard activity and acid production by the culture or completely stop acid production if the starter culture is

Media contra-flows are smaller flows, but they still represent multiple media sites of production, flow and identification. They are important but their impact remains small in comparison to dominant flows. Contra-flows can exist on the transnational level, such as Al-Jazeera, Euro-News, Bollywood, Brazilian shows and Korean drama.

Lipid production in R. toruloides was lower from arabinose and mixed carbohydrates than from glucose or xylose. Although high biomass and lipid production were achieved in both batch and fed-batch cultures with glucose as carbon source, for lipid production from mixtures of carbohydrates fed-batch cultivation was preferable.

Ball-milling influenced the molecular weight and monosaccharide composition of SPS and thus affected the performance of SPS in cellulase production. Finally, the crude enzymes produced in culture with SPS were used for saccharification and provided a 1.3-fold higher yield of glucose than that produced in culture without SPS.

The starter cultures normally used in the production of the majority of hard and medium-soft kinds of cheese not only cause the lactose to ferment, but also have the ability to attack the citric acid in the cheese simultaneously. This produces the carbon dioxide that contributes to formation of both round and granular eyes.

The re-use of culture media could be a solution for the development of large-scale cultures to minimize water use and nutrient consumption (Fret et al., 2017). For the cultivation of Scenedesmus obliquus , Livansky et al. (1996) found that water use and nutrient consumption could be reduced of about 64 and 16%, respectively, by recycling the growth medium.

Abstract In vitro air–liquid interface (ALI) cell culture models can potentially be used to assess inhalation toxicology endpoints and are usually considered, in terms of relevancy, between classic (i.e., submerged) in vitro models and animal-based models. In some situations that need to be clearly defined, ALI methods may represent a complement or an alternative option to in vivo
