Detailed explanation-1: -An average bacillus is 0.5-1.0 µm wide by 1.0-4.0 µm long.
Detailed explanation-2: -Bacillus is a genus of bacteria that are rod-shaped, aerobic and gram-positive.
Detailed explanation-3: -Bacteria display a wide diversity of shapes and sizes. Most bacteria are 0.2m (micron) in diameter and 2−8m (micron) in length. Bacterial cells are about one-tenth the size of eukaryotic cells. Q.
Detailed explanation-4: -An average rod-shaped bacterium measures about 1 um in diameter and 4 um in length. However, bacteria vary considerably in size ranging from 0.5 to 1.0 um in diameter to 10 to 20 um in length in some of the longer spiral forms.
Detailed explanation-5: -Bacillus species are rod-shaped, endospore-forming aerobic or facultatively anaerobic, Gram-positive bacteria; in some species cultures may turn Gram-negative with age. The many species of the genus exhibit a wide range of physiologic abilities that allow them to live in every natural environment.
