Solution Preview

There are several bacteria that are capable of fixing nitrogen; however, Rhizobium family is a well-known family that forms a symbiotic relationship with plants to fix atmospheric nitrogen. Bacteria of this family are Gram-negative and rod-shaped. They can reproduce by budding at one pole of the cell. They are motile due to peritrichous flagella, which can number from one to six. Species in this family produce slime composed of extracellular polysaccharides.

Bacteria are vital in the recycling of many vital elements that make up all living systems on Earth, such as oxygen, ...

Solution Summary

This solution answers questions about bacteria in the environment and their jobs. It discusses Bdellovibrio and E. coli, which microbes are responsible for the spoilage of food, and the functions of pharmaceuticals, such as growth hormone, human rennin, interferons, tissue plasminogen, and interleukin-2.

Microbiology Career Specialization

The science and practice of Microbiology impact on many facets of life and the functioning of the Earth. Microbiology also plays important roles in human affairs. As a testament to this, every spring, thousands of microbiologists gather for the Annual General Meeting of the American Society for Microbiology (ASM), which is the world's oldest and largest life science organization. These microbiologists represent a diversity of disciplines of microbiological specialization.
