Longer term, it no longer seems lunacy to believe in the possibility of "meat without feet" — meat produced in vitro, by growing animal cells in a super-rich nutrient environment before being further manipulated into burgers and steaks.
In temperate regions a pulse of polluting substances enters the alpine system with the annual snowmelt, bringing possibly detrimental consequences in this low-nutrient environment.
Even though the chemical, physical, and genetic bases of growth are elusive, much has been learned about the process by growing tissues in a sterile nutrient environment.
More importantly, nutrient environment affected the expression of genetic variation.
New findings in yeast describe how a metabolic gene network behaves in response to a changing nutrient environment.
Effectiveness of non-aflatoxigenic genotypes varies by crop, location and nutrient environment (Mehl and Cotty 2010, 2013; Mehl et al. 2012).
Photoacclimation models for marine phytoplankton describe the changes in their composition (typcially C, N and chlorophyll) and growth in response to changing light and nutrient environment.
The nutrient environment and metabolism play a dynamic role in cellular differentiation and research is elucidating the mechanisms that contribute to this process.
This suggests that genetically homogeneous viruses are less able to adapt to perturbations in the nutrient environment, hence medium changes should be avoided.
When a population of bacteria first enter a high-nutrient environment that allows growth, the cells need to adapt to their new environment.
