1. Classification

a. Higher order taxa

Higher Order Taxa: Bacteria; Firmicutes; Clostridia; Clostridiales; Clostridiaceae; Clostridium

Species: Clostridium tagluense

2. Description and significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

  • Include as many headings as are relevant to your microbe. Consider using the headings below, as they will allow readers to quickly locate specific information of major interest*

3. Genome structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?

4. Cell structure

Interesting features of cell structure. Can be combined with “metabolic processes”

5. Metabolic processes

Describe important sources of energy, electrons, and carbon (i.e. trophy) for the organism/organisms you are focusing on, as well as important molecules it/they synthesize(s).

6. Ecology and Pathology

Clostridium tagluense is a psychrotolerant bacteria that grows in a temperature range from 0-28 oC 2. The microbe creates spherical endospores that allow it to withstand temperatures below freezing. C. tagluense has an optimal pH of 6.5-7.2 and an optimal NaCl concentration of 0-2% 2. It is an obligate anaerobe that cannot grow in the presence of oxygen. These properties allow C. tagluense to reside in vacuum-sealed, frozen meat products and deep within permafrost 2. C. tagluense is not known to cause any human infections. Its main impact on human life lies in its ability to infect meat products. The microbe is known to cause blown-pack spoilage of vacuum-sealed and frozen meat 10. This type of spoilage is unlikely to cause disease in humans because meat with this spoilage is typically disposed of before consumption 11. Strains of C. tagluense have been isolated from spoilage juices from beef and samples of lamb femur bones 4, 10. The meat spoilage caused by C. tagluense can lead to legal and economic problems for the meat industry 11. C. tagluense spores have been found to survive treatment by peroxyacetic acid and the vacuum-sealing and cooling processes of meat packing 12. The best method to stop the growth of C. tagluense found is to lower the pH of its environment below levels it can withstand 4.

8. Current Research

Include information about how this microbe (or related microbes) are currently being studied and for what purpose
