MODEL RELEASED. Microbiological research. Scientist examining microbiological cultures in a petri dish

Bacterial antibiotic production. Colony of Streptomyces coelicolor bacteria growing on an agar medium (not seen) in a petri dish

Hydrating copper sulphate
Copper (II) sulphate crystals being hydrated. Anhydrous copper (II) sulphate is white, while hydrated copper sulphate is blue

Rocket seeds (Eruca sativa) in a petri dish of water. Soaking improves the germination rate of some plant seeds. It is also used as a method to determine the vigour of seeds

Phosphorus pentachloride hydrolysis. Spatula of phosphorus pentachloride (PCl5) being added to a petri dish of water (H2O). A reaction with water is called a hydrolysis reaction

Diffusion in agar
Diffusion. Image 1 of 2. Crystal of potassium dichromate (orange) in a petri dish containing agar gel. Over time, the crystal dissolves, spreading out to colour the entire dish

Bacterial culture. Petri dish containing bacterial cultures (red). The bacteria are grown on agar jelly (beige), which provides all the nutrients needed by bacteria for growth

In the world of microbiology, the a canvas for scientific exploration. It serves as a platform to cultivate and study various organisms, from bacteria to fungi. One captivating example is the culture of Aspergillus nidulans fungus, which thrives within these glass plates. When peering into a petri dish under a microscope, one can witness mesmerizing patterns formed by Paenibacillus bacteria. These intricate structures are adaptive responses to laboratory-imposed stresses that mimic their natural environments. The C type exhibits chiral formations, while the T type showcases tip-splitting morphotypes. The significance of petri dishes extends beyond bacterial cultures; they also play an essential role in plant biotechnology research. Scientists utilize these vessels to propagate and manipulate plants for various purposes such as genetic modification or disease resistance studies. Looking back at history, we find iconic images associated with this scientific tool. A colorful lithograph from 1948 depicts a chemistry set and microscope - symbols of discovery and experimentation. Another black-and-white photograph captures Alexander Fleming himself around 1945, whose groundbreaking work on antibiotics revolutionized medicine. Even before modern times, pioneers like Oswald Theodore Avery paved the way for our understanding of microbial life through their tireless efforts in bacteriology and molecular biology. And let's not forget historical depictions showcasing antibiotic action against harmful bacteria during the nineteenth century. From Salmonella cultures to diverse bacterial colonies thriving on agar surfaces - petri dishes have become indispensable tools in unraveling nature's microscopic wonders.
