21+ Spore Forming Bacteria Examples:Detailed Facts Around It


This article illustrates information on “spore forming bacteria examples” with all different types of bacterial species information in detail.

The word spore or endospore means it is one kind of “non-reproductive structure” that is formed during the condition of nutrient deprivation and some unfavorable or poor condition,that helps bacterial survival and growth.

Now take a look at spore forming bacteria example in details

Clostridium spp.

These bacteria belong to the species of the Clostridiaceae family. It is a most common spore forming bacteria examples.It is obligate anaerobes, rod-shaped and gram-negative bacteria which able to form endospores.The endospores are mostly in a bottle shape. The most common species of this bacteria are also able to form this endospores-like structure. The species are Clostridium botulinum,C.tetani and C.perfringes.

Clostridium botulinum

It is obligate anaerobes, rod-shaped and gram-negative bacteria which able to form endospores. These bacteria are mostly found in freshwater, soil, or naturally found in the environment. The endospores of this bacterial species are oval and very resistant. The vegetative cell is produced and also multiplies during the germination of endospores under favorable conditions and environments. It can grow and produce some toxin named botulinum neurotoxin that acts as a harmful agent.

Clostridium tetani

These bacteria are anaerobic, gram-positive bacilli, and endospore-forming bacteria. The species of this bacteria usually a rod-shaped but after the formation of the endospore, the shape is a change to drumstick and wider than the other species like bacillus. They are mostly found in dust, soil, and everywhere in the environment.

Clostridium perfringens

These bacteria are anaerobic, gram-positive, and endospore-forming bacteria. It is a type A strain of clostridium. They can able to survive in harsh and extreme adverse conditions for a longer period because they are more resistant to cold and heat. The germination time of endospore is very fast and short compared to other organisms and it’s around 6.3minuts.

Bacillus spp.

These bacteria belong to the species of the Bacillaceae family. It is a most common spore forming bacteria examples.It is a gram-positive, rod-shaped, and protective endospore-forming bacteria. Different species of this bacillus form endospores are Bacillus thuringiensis, Bacillus cereus and Bacillus anthracis.

Bacillus thuringiensis

The bacteria is a gram-positive, rod-shaped, and protective endospore-forming bacteria. The vegetative cell contains endospore with released some toxin crystals which act as a delta-endotoxin or also known as crystals of insecticidal protein toxin which have a bipyramidal shape.

Bacillus cereus

The bacteria is a motile, gram-positive, usually aerobic or facultatively anaerobic, and resistant endospore-forming bacteria. most of them form spores in the presence of oxygen. The endospores of this bacteria produce different kinds of enterotoxins like heat-stable emetic cereulide toxin and some tissue destructive enzymes.

Bacillus anthracis

The bacteria is a rod-shaped, gram-positive, aerobic spore-forming bacteria that form spores that are oval-shaped. During the non-reproductive cell have a deficiency of certain nutrients, it starts to form the spore.  The spore of this bacteria can able to survive in very harsh conditions as well. The spores of this bacteria act as infectious particles of toxin named anthrax.

Sporolactobacillus spp.

These bacteria belong to the species of the Sprolactobacillaceae family. The bacteria are gram-positive, rod-shaped, anaerobic, and form resistant and dormant forms of endospores. The most common species of this bacteria include, Sporolactobacillus dextrus, Sporolactobacillus terrae, Sporolactobacillus laevis, Sporolactobacillus vineae , Sporolactobacillus inulinus

Sporosarcina spp.

These bacteria belong to the species of the Caryophanaceae family. The bacteria are gram-positive, heterotrophic, and rod-shaped and some of the species are aerobic or facultative aerobic. They are able to form endospores. The most common species of this bacteria are Sporosarcina aquamarine and Sporosarcina halophila, Sporosarcina ureae. These all species of bacteria belong to the species of the Planococcaceae family. It is a gram-positive, motile, aerobic, and spore-forming bacteria.

Thermolithobacteria

These bacteria belong to the Thermolithobacteraceae family. It is a rod-shaped gram program. The most common species of this bacteria are Thermolithobacter ferrireducens and Thermolithobacter carboxydivorans.

Thermoactinomyces vulgaris

These bacteria belong to the Thermoactinomycetaceae family.It is a most common spore forming bacteria examples.It is a gram-positive bacteria. It can also able  to form endospores where In a natural habitat with extreme longevity, it can form viable endospores.

Sporohalobacter

These bacteria belong to the Haloanaerobiaceae family. It is an anaerobic and spore-forming bacteria. It can able to live and grow in hypersaline environments. The most common species of this bacteria that can form endospores are Sporohalobacter salinus  and Sporohalobacter morettii.

Oxobacter

These bacteria belong to the Clostridiaceae family. It is a rod-shaped, obligatory anaerobic, and endospore-forming microorganism. They can able to do catabolize activity to convert private into acetic acid and carbon dioxide. The most common species of this bacteria is Oxobacter pfennig.
