Question

What are Actinomycetes? Are they Fungi or Bacteria?

Answer 1

Hint: Gram-positive bacteria are bacteria that test positive in the Gram stain test, which has historically been used to swiftly categorise bacteria into two main groups based on their cell wall type. When Gram-positive bacteria are stained with the crystal violet dye used in the test, they appear purple when seen under an optical microscope. This is because the stain is retained after it is washed away from the rest of the sample during the decolorization step of the test by the thick peptidoglycan layer in the bacterial cell wall.

Complete answer:
Actinomycetales is an Actinobacteria order. An actinomycete is a member of the order Actinomycetales. They have filamentous and branching mycelia with a gram-positive and anaerobic growth pattern. Some actinobacteria have the shape of rods or coccoids, while others produce spores on aerial hyphae. Bacteriophages, sometimes known as actinophages, can infect Actinomycetales bacteria. Actinomycetales include bacteria that are harmless to pathogens that are resistant to antibiotics. Actinomycetales are typically found in soil and decomposing organic waste, but they may also be discovered in live creatures like people and animals. They develop symbiotic nitrogen-fixing relationships with over 200 plant species and may also act as growth promoters or biocontrol agents, as well as cause disease in some plant species. In the form of Helicobacter, Actinomycetales can be found in the human urogenital tract as well as the digestive system, including the mouth, throat, and gastrointestinal tract, without producing illness in the host. They are also utilised as a source of numerous antibiotics and insecticides, and have a wide range of medical and botanical uses.

Note:
Under specific circumstances and growth medium, several Actinomycetes species generate antibacterial chemicals. Medically significant antibiotics isolated from Actinomycetes bacteria include streptomycin, actinomycin, and streptothricin. Actinomycetes are responsible for about two-thirds of all natural antibacterial medication compounds now in use.
