A Princeton University team has now developed a method for observing bacteria in 3-D environments. They discovered that when the bacteria grow, their colonies consistently form fascinating rough shapes that resemble a branching head of broccoli, far more complex than what is seen in a Petri dish.

The Petri dish remained almost unmodified, apart from the use of plastic, and became the most commonly used piece of microbiological equipment. Recent microbial cultivation technologies, however are starting to include highly subdivided multi-well plates and capillaries, as well as methods of sorting and counting encapsulated micro-colonies 10-11.

Colony morphology is a way scientists can identify bacteria. In fact there is a book called Bergey's Manual of Determinative Bacteriology (commonly termed Bergey's Manual) that describes the majority of bacterial species identified by scientists so far.

The Answer: The bacteria dish will be full at 09.14 AM or 1 minute after 09.13 AM. Data from The Question: Bacteria duplicates itself per minute. At 09.00 AM, the experiment started with a single cell of bacteria. At 09.13 AM, the dish was half full. The Question: At what time will the dish be complete?

Mutations and natural selection—two primary agents of change—work together to sculpt new genetic combinations, allowing bacteria to resist antibiotic chemicals in their environment. Now you can watch a powerful illustration of E. coli bacteria evolving antibiotic resistance in a video produced by scientists at the Harvard Medical School.

In 1928, British bacteriologist Frederick Griffith conducted a series of experiments using Streptococcus pneumoniae bacteria and mice. Griffith wasn't trying to identify the genetic material, but rather, trying to develop a vaccine against pneumonia. In his experiments, Griffith used two related strains of bacteria, known as R and S.

Datta said two factors seemed to cause the broccoli-shaped growth on a colony's surface. First, bacteria with access to high levels of nutrients or oxygen will grow and reproduce faster than ones.

At 9:00 am, there is 1 cell, and at 9:13 am, the dish is half-full, which means there are 2^(13-9) = 2^4 = 16 cells. So, it took 4 minutes for the dish to go from 1 cell to 16 cells. If the dish is half-full at 4 minutes, it will be completely full at the next minute. Therefore, the dish will be full at 9:13 am + 4 minutes = 9:17 am.
