Vernon wanted to determine the colony forming units of bacteria per gram of soil in their school garden. He obtained 10 grams of soil from the garden and serially diluted it. He spread plated the samples of 10-3, 10-4, and 10-5 After incubation, the colony counts are as follows: 1:1000 1:10 000 1:100 000 TNTC, TNTC* 222, 217 19, 13 *Too numerous to count Calculate for the CFU/g of bacteria. Show your solution and express your final answer to 2 significant figures.
Bacterial Morphology
The bacteria are prokaryotic organisms that are single-celled, and are found to exist as free-living and possess a microscopic size. The morphology is found to vary in the bacteria, where some of them are identified as individual organisms and the others are detected as colonies. The size and shape of the bacterial cell also represent its morphology.
Bacterial cell structure
Bacteria are single-celled, tiny creatures that may enter healthy tissues and grow rapidly. Bacteria are microscopic organisms that are tiny and unicellular. These are members of the prokaryote kingdom. They live in water, air, soil, and all-natural environments. They are used in industrial and therapeutic processes, and they support a wide range of plant and animal life. The first organism to appear on the planet. Bacteria-like creatures are the oldest known fossils. Bacteria can consume a wide range of organic and inorganic elements, and some may even survive in harsh conditions.
