Fermenters are used for the biotechnological production of enzymes and other products using bacteria, yeast and cell cultures. For educational purposes a bubble bioreactor used in this experiment is a more convenient and ecomical alternative to commercial fermenters. To demonstrate how ferm ...
Principle
The properties of the micro-organism Zymomonas mobilis have been used in the production of alcohol for centuries. Nevertheless, the bacterium in palm wine and pulque, the fermented juice of the agave plant, was not identified and recognised as being ...
Scientists first recognised importance of certain bacteria for the extraction of metals from ore in the 1950s. Nowadays t ...
To prepare and analyse diagrams to illustrate the transpiration of plants, depending on different environmental conditions, using a wireless data acquisition system:
Representation of the photosynthesis rate of a plant by measuring the oxygen pressure increase, in white and green light as well as in the dark.
Measurement of the photosynthesis rate as a function of light intensity by counting the oxygen bubbles that are released by a water plant.
The cell membrane controls the transport of nutrients and water into the cell as well as the transport of waste products and water out of the cell. This can be passive, i.e. caused by osmotic processes, as well as active. The aim of this experiment is ...
Why are there only a few different kinds of plants in a deciduous forest? Except for having trees that are all approximately of the same height, hardly any other plants grow in a deciduous forest, except for young plants of the same type of trees. Th ...
Principle and tasks
To investigate the effect of soil temperature on the germination of garden cress (Lepidium sativum). To determine the most favourable value for the germination and growth of cress using a temperature organ.
