1. Actinomycetes
gram-positive bacteria that can form branching filaments. They may form true mycelia or produce conidiospore s.

2. Anthrax
Anthrax is an infection by the gram-positive spore-forming aerobic rod-shaped bacterium, Bacillus anthracis. It usually affects sheep, cattle, horses, goats, and swine. It may infect humans, causing meningitis and pneumonia with a high rate of death.

3. Bacillus amyloliquifaciens
B. amyloliquifaciens is a gram-positive , rod-shaped bacterium used to produce alpha- amylase and serine protease .

4. Bacillus licheniformis
B. lichemiformis is a gram-positive , rod-shaped bacterium which is used in the biotech industry to produce the protease enzyme subtilisin.

5. Bacillus popilliae
B. popilliae is a gram-positive bacterium which attacks only the Japanese beetle (Popillia japonica) and is therefore used in some places in the U.S. to kill the beetles. When the larvae are infected, they turn white because of all the bacterial spores (endospores) that develop in the insects' hemolymph (blood equivalent).

6. Bacillus subtilis
B. subtilis is a gram-positive , rod-shaped, nonpathogenic bacterium which lives in soil. Its genome has been widely studied and is frequently used in genetic engineering and microbiology experiments.

7. Bacitracin (Altracin, Ayfivin, Fortracin, Penitracin, Topitracin,Zutracin)
An antibiotic that inhibits the growth of cell walls in gram-positive bacteria.

8. Bacterial endospore
A dormant body which certain gram-positive bacteria can develop within them under conditions of stress (like lack of nutrients), which is highly resistant to harsh environmental conditions and which can develop into a new, live bacterium once conditions are good again.

9. Cell wall
A structure that forms the outer surface of plant cell s, fungi cells, and certain bacterial cells (the gram-positive species ) and is on the outside of the cell membrane . The cell wall is a rigid structure which helps the cell keep its shape and gives the cell strength.

10. Cornybacteria
A group of small, gram-positive bacteria which come in a number of shapes from straight and curved rods to club shapes. One member of the group, cornybacterium diphtheriae, causes the disease diphtheria.
