microbial cells are producers of natural polymers present in plant cells. production of pullulan (an extracellular microbial polysaccharide) by aureobasidium pullularia pullulans (p. pullulans) was studied under fermentation conditions, and kinetic parameters were determined. pullulan formation obeyed a growth and non-growth associated term. phb (polyhydroxybutyrates) an intracellular biopolyme...

Within the embryology laboratory one of the central components is embryo culture media. The fundamental goal/role of the laboratory and therefore the culture media has been to maintain the inherent viability of the gametes/embryos before replacement to the mother. Over the last 10-15 years there have been major advancements in this area, with culture media developing from simple salt solutions ...

Fetal bovine serum (FBS) is a ubiquitously used essential supplement in cell culture media. However, there are serious scientific and ethical concerns about the use of FBS regarding its harvest and production. During the last three decades, FBS could be substituted by other supplements or by the use of defined chemical components in serum-free cell culture. A number of serum-free medium formula...

The green colonial microalga, Botryococcus braunii is well known for its high lipid content and has already been proposed as a renewable energy source for various aquaculture and biotechnological applications. However, due to its slow growth rate compared with other microalgae, B. braunii has not yet been used in mass culture to produce more biomass. Therefore, in this study we tested different...

Background Cell culture technology has spread prolifically within a century, a variety of culture media has been designed. This review goes through the history, characteristics and current issues of animal-cell culture media. Methods A literature search was performed on PubMed and Google Scholar between 1880 and May 2016 using appropriate keywords. Results At the dawn of cell culture techno...

This paper examines the mutual relationship between the communication richness of media used for conducting organizational communication and organizational culture. The richness of the media influences how well the organization might maintain its culture. On the other hand, a strong organizational culture allows a more effective use of the media by providing members with some of the necessary c...
