Human Interactions With Microbes
Human interactions with microbes include both practical and symbolic uses of microbes, and negative interactions in the form of human, domestic animal, and crop diseases. Practical use of microbes began in ancient times with fermentation in food processing; bread, beer and wine have been produced by yeasts from the dawn of civilisation, such as in ancient Egypt. More recently, microbes have been used in activities from biological warfare to the production of chemicals by fermentation, as industrial chemists discover how to manufacture a widening variety of organic chemicals including enzymes and bioactive molecules such as hormones and competitive inhibitors for use as medicines. Fermentation is used, too, to produce substitutes for fossil fuels in forms such as ethanol and methane; fuels may also be produced by algae. Anaerobic microorganisms are important in sewage treatment. In scientific research, yeasts and the bacterium ''Escherichia coli'' serve as model organisms e ...

Tomb Of Nakht (13)
The Theban Tomb TT52 is located in Sheikh Abd el-Qurna, part of the Theban Necropolis, on the west bank of the Nile, opposite to Luxor.

Architecture The tomb architecture and decoration conforms to the standard design of Theban tombs of the New Kingdom by using such scenes that are commonly found in contemporary tombs. Some of these decorations display differences from scenes found in Old Kingdom mastabas of Memphis, where one of the principal functions of the tomb was to ensure magical sustenance for the ka, whereas in the New Kingdom tombs, the primary function was to identify oneself on the tomb walls. The tomb has the typical T-shaped architectural design that was common for non-royal Theban tombs of th ...
