Biotechnology is a field of applied biology that involves the use of living organisms and bioprocesses in engineering‚ technology‚ medicine and other fields requiring bioproducts. The concept encompasses a wide range of procedures for modifying living organisms according to human purposes. For thousands of years‚ humans have used selective breeding to improve production of crops and livestock to use them for food. In selective breeding‚ organisms with desirable characteristics are mated to produce

English 101 Dr. Coffe 8 December 2013 Genetically Modified Food According to the U.S Department of Agriculture‚ also known as USDA‚ in the United States more than 90% of soybeans‚ cotton‚ corn‚ and certain other crops are genetically engineered. GMOs are organisms that are introduced into plants or meat to alter their DNA. Their main purpose is to create food that can withstand many different environments and climates. The problem with GMO’s is that they have been shown to create health problems

These substances primary function is to kill or injure the host. Biological weapons can be used to harm vulnerable organisms such as humans‚ animals or vegetation (Biological Threats

The spot inoculation method was followed for antifungal activity of bacterial strain Paenibacillus elgii TS33 25. The nutrient agar medium was prepared‚ sterilized at 121ºC‚ poured into the sterilized peteriplates and allowed to solidify under aseptic conditions. After solidification bacterial strain Paenibacillus elgii TS33 was spot inoculated on nutrient agar medium and incubated at 37ºC for 48 hours. After incubation the molten potato dextrose agar medium containing the spores of test fungus‚

Also‚ it improve the virus resistance of crop‚ for example: The Golden Rice‚ scientist add the genes for toxin production from the bacterium Bacillus Thuringiensis‚ this helps to in expend the production of rice.

I noted this result and looked at the lab key to see what the results narrowed my bacteria choices to. My possible results were now: Bacillus cereus‚ Mycobacterium smegmatis‚ or Lactobacillus acidophilus. Next I preformed the acid fast staining. When preparing this slide and viewing it on oil immersion‚ I was a little more

Introduction Succession is the measurable process in which a community changes and thus the community as a whole is altered (Friedman 2017). To study succession‚ one must use one of the following methods: to observe any patterns that occur‚ to conduct experiments that manipulate specific variables in a community‚ or to construct a model that may undergo succession. One example of an experiment that measures microbial succession was an experiment observing changes in traditional Chinese soy sauce

The fungal extracts were assessed for antibacterial activity against three standard pathogenic bacterial strains: Bacillus subtilis‚ Staphylococcus aureus and Escherichia coli. Most of the extracts showed in vitro inhibition of bacterial growth. The phytochemical screening revealed the existence of a diverse group of secondary metabolites in the crude extracts of the
