Introduction:

These are prokaryotes, which means nuclear materials are not membrane-bound in them. They may or may not have a cell wall and can be autotrophic or heterotrophic. All organisms of this kingdom are unicellular. These organisms are the simplest and oldest forms of life on Earth. They are incredibly diverse and play essential roles in the environment, human health, and industry. They are microscopic and come in various shapes, such as spherical (cocci), rod-shaped (bacilli), spiral (spirilla), and comma-shaped (vibrios).

Experiment

1. Aim: To observe lactobacilli bacteria in curd or buttermilk under a compound microscope.

2. Requirements: a clean glass slide, a drop of curd or buttermilk, water, a cover slip, and a compound microscope.

3. Procedure

  • Take a clean glass slide and place a small drop of curd or buttermilk on it.
  • Add a tiny amount of water to dilute the drop.
  • Carefully place a cover slip over the drop to avoid air bubbles.
  • Use a compound microscope to observe the sample under high power.

4. Observation: Small, moving, rod-shaped microbes, known as lactobacilli bacteria, can be observed.

5. Conclusion: The experiment shows that curd or buttermilk contains lactobacilli bacteria, which are part of the Kingdom Monera. This kingdom includes all types of bacteria and bluegreen algae.
