What is the morphology and arrangement of Bacillus subtilis?

Bacillus subtilis morphology describes rod-shaped, Gram-positive bacteria that show up on both positive and negative Gram stain techniques. A bacterial rod is a symmetrical cylinder with rounded ends. A significant difference in pressure across the cytoplasmic membrane pushes the cell wall into a specific shape.

Does Bacillus subtilis demonstrate any cellular arrangement?

Bacillus subtilis has a single chromosome that replicates bidirectionally. Peptidoglycan surrounds its cell, and it utilizes a flagellum for motility. Bacillus subtilis arrangement is quite diverse, and they may be arranged as single or chain cells.

What is the difference between cell morphology and cell arrangement?

While arrangement refers to the groupings of individual cells, morphology describes the appearance of groups of bacteria, or colonies. Colony shapes can be round, irregular, filamentous or curled.

What is the colony morphology of Bacillus subtilis?

Bacillus subtilis is a typical germ, which is rod-shaped and Gram-positive. When cultured on ordinary nutrient agar, the morphology circular colony of this bacteria is rough, opaque, fuzzy white or slightly yellow with jagged edges [1, 7].

What is the arrangement and cell morphology of Bacillus?

Shape of Bacterial Cell Bacilli (or bacillus for a single cell) are rod-shaped bacteria. Spirilla (or spirillum for a single cell) are curved bacteria which can range from a gently curved shape to a corkscrew-like spiral.

What is the arrangement of Bacillus?

Bacilli usually divide in the same plane and are solitary, but can combine to form diplobacilli, streptobacilli, and palisades. Diplobacilli: Two bacilli arranged side by side with each other. Streptobacilli: Bacilli arranged in chains. Coccobacillus: Oval and similar to coccus (circular shaped bacterium).

What is the structure of Bacillus subtilis?

Bacillus subtilis are rod-shaped bacteria that are Gram-positive (Perez 2000). The cell wall is a rigid structure outside the cell. It is composed of peptidoglycan, which is a polymer of sugars and amino acids. The peptidoglycan that is found in bacteria is known as murein.

What is the arrangement and cell morphology of bacillus?

What is the arrangement of bacillus?

The bacilli are arranged in chains, as the cells divide in one plane.

How many different bacillus arrangements can be found?

There are three basic shapes of bacteria: coccus, bacillus, and spiral. Based on planes of division, the coccus shape can appear in several distinct arrangements: diplococcus, streptococcus, tetrad, sarcina, and staphylococcus. The bacillus shape can appear as a single bacillus, a streptobacillus, or a coccobacillus.
