Study Notes
Gram-Negative Bacteria
- Spheroplasts are formed when Gram-negative bacteria are treated similarly, retaining much of their outer membrane structure.
- The distinctive feature of Gram-negative bacteria is lipopolysaccharides (LPS), also known as endotoxin, which is composed of different molecular types.
Structure and Function
- LPS is present in all Gram-negative species, with varying numbers depending on the species.
- Flagella are long, flexible structures used for motility.
- Pili (or fimbriae) are short, rigid, hair-like structures scattered on the bacterial surface, used for attachment.
Composition
- Pili consist of 97-98% water and 2-3% dissolved solids.
Endospores
- Endospores are highly heat-resistant, dehydrated resting cells formed intracellularly, mainly in Bacillus and Clostridium genera.
- Endospores are resistant to chemical reactions that lead to decomposition and breakdown of large molecules into smaller, simpler ones, resulting in energy production.
