Interpreting Plates - Science Buddies
What Can Grow on a Nutrient Agar Plate? Bacteria. Each distinct circular colony should represent an individual bacterial cell or group that has divided repeatedly. Being kept in one place, the resulting cells have accumulated to form a visible patch. Most bacterial colonies appear white, cream, or yellow in color, and fairly circular in shape.
Identifying Bacteria Through Look, Growth, Stain and Strain
Feb 7, 2020 · Buffered charcoal yeast extract agar selects for some Gram-negatives, especially Legionella pneumophila. Sarbouraud’s agar, which has a low pH and high glucose concentration, selects for some fungi. Differential media: X-gal plates identifies lac …
Colony Morphology of Bacteria and Examples - Biology Notes …
Mar 27, 2024 · When certain microorganisms grow in blood agars, they can consume blood within the medium, leading to apparent hemolysis (destruction of red blood cells) on the Agar plate. In the colonial morphology, hemolysis can be divided …

2.2: Introduction to Bacterial Growth and Aseptic Techniques
May 26, 2021 · Describe general characteristics of bacterial growth on agar plates; Explain how to inoculate growth media using proper aseptic procedures; Describe the process for inoculating sterile media; Describe the procedure (T-streak) for isolation of single bacterial colonies
Colony Morphology – its shapes and appearance - Microbial Notes
Feb 10, 2023 · On the surface of the agar plate, staphylococci produce opaque, smooth, and round colonies. What purpose does colony morphology serve? Identification of bacterial species depends heavily on colony shape and its traits.
A Look Inside the Bacteriology Lab: What Does Your Culture …
Besides urine and blood, stool specimens are routinely cultured to identify bacteria – like Salmonella, Shigella, or Campylobacter – that cause food poisoning. You can also test for fungal infections like ringworm, a yeast infection or oral thrush, which appears as …
species identification - What are these white, fuzzy dome-shaped ...
Dec 15, 2022 · The contaminant could have come from the top agar, which was stored in a 55°C water bath. We created four of these plates at the same time, and they all had the same contaminant. What species could these dome-shaped white colonies belong to?
Bacterial Colony Morphology 101 - Hudson Robotics
Its definition is simple: colony morphology is simply the appearance of the colony once it grows on an agar plate. The visual cues provided by a cultivated bacterial colony serve as an important way for microbiologists to identify and isolate them via colony picking for other applications.
Observing Plates - Davidson
When observing your plates, you should notice several things. First, in locations where bacteria are crowded closely together, confluent growth appears. In areas where the bacteria are more spread out, though, individual colonies should appear.
