To name a new bacterium, microbiologists have several conventions at their disposal. All that matters is that the new name be different from all other names in biology. 1 shows common naming conventions. 1 Origins of bacteria names Naming Method Example Reason for the Name In honor of a famous Pasteurella microbiologist multocida Genus named for Louis Pasteur Unique feature Magnetospirillum magnetotacticum Spiral-shaped bacteria with magnetcontaining magnetosomes inside their cells Extreme growing conditions Thermus aquaticus Grows in very hot waters such as hot springs Bacterial names will likely never be replaced regardless of scientific advances in classifying and reclassifying the species.
Three years after Koch and Hesse switched to agar-based media, another assistant in the laboratory, Richard J. Petri, designed a shallow glass dish to ease the dispensing of the sterilized molten media. The dishes measured a little less than a half-inch deep and 4 inches in diameter. This Petri dish design has never been improved upon and is a staple of every microbiology lab today. 3 Pouring molten agar. Agar melts when sterilized, and then solidifies when it cools to below 110°F. The microbiologist here pours the agar aseptically from a sterile bottle to a sterile Petri dish.
The common soil inhabitant Bacillus breaks down proteins, fats, and carbohydrates by excreting the enzymes protease, lipase, and amylase, respectively. Thousands of other species break down organic matter in similar ways. For example, Cellulomonas bacteria produce the enzyme cellulase—rare for bacteria—that digests plant cellulose fibers. Bacteria emit carbon dioxide as an end product, which enters the atmosphere. A massive population of photosynthetic bacteria in the Earth’s surface waters then captures this gas and inserts the carbon into a new food chain of bacterial cells, protozoa, invertebrates, and so on until the carbon ends up in tuna sashimi on a restaurant menu.
