A compound microscope is enough to observe a bacterium. But as per the need of clarity & resolution ,one can use electron microscope etc.
To learn about the bacteria you are incubating by observing or experimenting.
Telescopes are used for observing stars.
A Petri dish is used in scientific research to culture cells, bacteria, or other microorganisms in a controlled environment. It provides a flat, transparent surface for observing growth and interactions between organisms.
Antony Van Leeuwenhoek discovered bacteria by observing the plaque between his own teeth (as well as others) under a microsope and are known as animal cules which are protozoans
The gene commonly used to identify bacteria carrying a plasmid is the beta-lactamase gene, which confers resistance to beta-lactam antibiotics. Bacteria harboring plasmids with this gene can be identified by growing them on agar plates containing beta-lactam antibiotics and observing which colonies survive.
There are no bacteria on the slide.Your lens cap is on.You are not looking in the right place.The microscope is in the wrong focus.
Genetically modified bacteria can be used to produce. This is a transgenic bacteria.
Agar slopes are growth media for bacteria in bottles. Mainly used to transport the bacteria or for counting colonies. http://en.wikipedia.org/wiki/Bacteriological_water_analysis#Pour_plates

A Gram stain is commonly used to observe bacteria in a sputum sample. This staining procedure helps visualize the bacterial cell wall structure and arrangement, aiding in the identification of different bacterial species.
Bacteria has been used to make cheese.
