• Pruteen(animals fed) is produced by mass culture of Methylophilus methylotrophus bacteria. 

  • Mycoprotein made from Fusarium venenatum fungus.

  • To add flavor by fermenting meat Lactobacillus plantarum and Pediococcus cerevisiae bacteria's are added
  • To produce distinctive flavor Penicillium and Aspergillus fungus are added.   

  • Beer and Wine are made by fermenting sugary juices.  
  • Spirits like whiskey ,gin, and rum are made fermenting juices.  
  • Fermentation produces ethyl alcohol, carbon dioxide, amyl and isoamyl alcohols and acetic and butyric acids which add to the flavor of the beer.  

  • The most common microbes in bread making is Saccharomyces cerevisiae to make the dough remains dense, flat and hard.
  • The yeast metabolism requires a source of fermentable sugar such as maltose or glucose. It ferments aerobically so produces carbon dioxide and water rather than alcohol.     

           

  • Is the process of transferring DNA from one organism to another organism.

  • Results in a genetic modification; the production of a transgenic organism. 

  • Genetic engineering in animal breeding is uses to increasing growth rate, improving milk production, modification of hair, increasing disease resistance 

  • Is a method of a biological research in which fragments of tissue from an animal or plant are transferred to an artificial environment in which they can continue to survive and function.
