Einzeller im Heuaufguss

Einzeller im Heuaufguss

• Zellkultur: A method to cultivate microscopic organisms, specifically using hay infusion
• Material: A glass jar, hay, and water from a puddle or rain barrel create a suitable environment to grow microscopic organisms
• Observation: A microscope is necessary to view the variety of microscopic organisms in significant numbers
• Hay Infusion: The hay is submerged in water, and the suspension is left in a warm place to facilitate growth

Hay Infusion Technique

• Setup: A glass jar with 2-3 grams of hay is filled. The hay is covered, leaving space between the hay and the top.
• Conditions: To allow for the growth of organisms, the jar needs to be kept warm. A lid is not needed because the organisms need oxygen to thrive.
• Growth: A film, called the Kahmhaut (a white film), develops on the surface of the water.
• Organisms: The organisms in the hay infusion feed on the hay and contribute to the growth of other organisms in and on the hay.

Observation and Identification

• Microscope Use: A microscope is indispensable for a detailed examination and identification of the organisms.
• Collecting Sample: Use a pipette to obtain a sample from beneath the Kahmhaut to analyze with a microscope.
• Observation Focus: Examine the organisms, their structure, motility, feeding strategies, etc.
• Comparison: Compare the observed organisms with existing classifications of organisms.

Specific Organisms (with examples)

• Pantoffeltierchen: A specific organism and its movement, as well as the effect of gelatin.
• Amöbe: A microscopic single-celled organism.
• Glockentierchen: A microscopic single-celled organism.
• Waffentierchen: A microscopic single-celled organism.
