what is the bacteria that can be seen with naked eye?

Answer 1

A team of German scientists studying sediment samples collected off the coast of Namibia say they have discovered the largest bacteria cell ever observed.

The organism can grow to as large as 3/4 of a millimeter across, which means it is visible to the naked eye as a speck -- about the size of the period at the end of this sentence.

To put the size of the big bacterium in perspective, it is a true giant in the world of the very small. For instance, scientists, drawing an analogy, said if the largest of the newly discovered bacteria was the size of a blue whale, the typical bacterium would be the size of a new-born mouse.

As for what it looks like, the large bacteria shines kind of like an opal -- blue, green and white. They grow in long, loosely connected strands, reminiscent of a strand of pearls.

The bacteria is named Thiomargarista namibiensis, which means "Sulfur Pearl of Namibia."

Answer 2

I remember a couple of years ago the report from Africa about the bacteria found in the Atlantic ocean shores. Individual cells are the size of an ink pen dot. They grow in strings. I don't remember the name, but run a search with the key words Africa, Atlantic and bacteria.

Answer 3

Larger than life bacteria were isolated from a kind of surgeon fish (Source: JC Brown). Large bacteria were also found off the coast of Namibia. The Thiomargarita namibiensis can be seen with the naked eye! (Source: Microbes at ASM).

A single-cell organism has been found that is large enough to trip over! This little? critter was discovered within a Red Sea surgeonfish, >>-)))))))o > [the best surgeonfish - what is that, anyway? - I could do..] and was first thought to be a protozoan (another kind of little critter - but unlike bacteria, pretty big - big enough to see without a microscope). Remember, we can't see anything that is less than about 200 micrometers in size (200-millionths of a meter - which would appear as an incredibly tiny speck, but could indeed be seen). Bacteria range from about 0.2 micrometer to 1.5 micrometers. (this "sizing" in fact, is one means of classifying something as a bacterium, and not a horse). Take a gander at some relative sizes of living cells by accessing Jim Sullivan's Page at: Cells Alive! This bug we are presently discussing, Epulopiscium fishelsoni is almost 250 micrometers! However, Norman Pace, now at the University of California, Berkeley, has been looking at the genes of this bug and is using PCR (polymerase chain-reaction) to amplify DNA sequences known to be associated only with bacteria. From these studies, Pace has produced evidence that this bug is actually a bacterium! If the data hold up, and they appear to be pretty darn strong, then this bug will be the largest bacterium ever discovered - several hundred-times larger than the largest known bacterial cell. You could spot the darn thing on your tablecloth! This information is causing quite a stir among taxonomic types, and is causing everyone who works on bacterial physiology, bacterial genetics, and, who classify bacteria, to re-evaluate things - especially the rules of classification. Ah, science, the more we learn, the more we need to learn. Keeps you hoppin'.

Take a look at a related article which discusses the fact that bacteria of this species (Epulopiscium) have babies! Please see: Bacteria Have Babies - No Kidding!

ALSO

Without even looking at it under a microscope, Andreas Teske could tell immediately that this bacterium was unusual.

That’s because he didn’t need a microscope. Unlike other bacteria, this one could be seen with the naked eye. The newly discovered bacterium is about as large as the period at the end of this sentence, making it gargantuan by bacterial standards. It was found buried in smelly, sulfur-rich, sedimentary, seafloor muck off the coast of Namibia. Growing in long lines of single cells, each stuffed with reflective white globules of sulfur, the bacterium resembled a string of pearls to its discoverers, who named it Thiomargarita namibiensus -- “Sulfur pearl of Namibia.”
