The article entitled, “The advantages of spore forming bacteria is quite intriguing”. My college studies were telling me they were spoilage microorganisms, toxin producing and relatively hard to kill. Those characteristics are advantageous to microorganisms itself but not to manufacturers and consumers.
The spore forming bacteria a.k.a. the endospore forming bacteria are able to convert itself to a defensive dormant structure when the environment becomes unfavorable and wait until condition become conducive.
Bacterial endospore has several protective layers. 1) The outer proteinaceous coat – provides chemical enzymatic resistance. 2) Specialized peptidoglycan cortex – provides resistance to high temperature. 3) Germ cell wall – will become the bacterial cell wall when activates. 4) Inner membrane – barrier against harmful chemicals. 5) The central core in a very dehydrated state. 6) Small acid-soluble proteins (SASPs) which tightly bound and condensed the DNA enables UV resistance. Other bacterial spores may have stalks, toxin crystals and additional shell layers which add extra protection.
There are cases where bacterial endospore are advantageous not only to itself but to human too. A probiotic microorganism is one. Like the new ProDura strain of spore-forming probiotics by Nebraska Cultures. A strain of Bacillus coagulans that has great potential. Its heat stability and extreme resilience make it suitable to undergo food processing conditions and later do its probiotic function once in human tummy.
