Contrasting community composition of endospores and vegetative Firmicutes in a marine sediment suggests both endogenous and exogenous sources of endospore accumulation.

Environmental Microbiology Reports, 2018
Bacterial endospores are highly abundant in marine sediments, but their taxonomic identity and ecology is largely unknown. We selectively extracted DNA from endospores and vegetative cells and sequenced 16S rRNA genes to characterize the composition of ...

Flow electrochemical inactivation of waterborne bacterial endospores

Journal of Hazardous Materials, 2023
Waterborne pathogens have the risk of spreading waterborne diseases and even pandemics. Some Gram-positive bacteria can form endospores, the hardiest known life form that can withstand heat, radiation, and chemicals. Electrochemical inactivation may offer a promising solution, but is hindered by low inactivation efficiencies resulting from limitation ...

Differential Staining of Bacteria: Endospore Stain

Current Protocols in Microbiology, 2009
AbstractEndospore production is a very important characteristic of some bacteria, allowing them to resist adverse environmental conditions such as desiccation, chemical exposure, extreme heat, radiation, etc. The identification of endospores is also very important for the clinical microbiologist who is analyzing a patient's body fluid or tissue—there ...

Raman spectroscopic study of bacterial endospores

Analytical and Bioanalytical Chemistry, 2007
Endospores and endospore-forming bacteria were studied by Raman spectroscopy. Raman spectra were recorded from Bacillus licheniformis LMG 7634 at different steps during growth and spore formation, and from spore suspensions obtained from diverse Bacillus and Paenibacillus strains cultured in different conditions (growth media, temperature, peroxide ...

Evaluating plant performance with endospores

Journal AWWA, 1996
Monitoring for indigenous spores of aerobic spore‐forming bacteria proves a viable method of assessing treatment plant performance.Spores of aerobic spore‐forming bacteria were used as microbial surrogates for evaluating drinking water treatment plant performance. A method for assaying for the microbial surrogate was developed.

[Actinomyces thermovulgaris endospores].

Mikrobiologiia, 1978
It has been established for the first time that autolysis observed when Actinomyces thermovulgaris T-54 is cultivated on liquid media of various composition is caused by the formation of submerged spores. These, in contrast to exospores of the majority of the actinomycetes, are endospores according to their structure and the following criteria ...

Bacillus subtilis Systems Biology: Applications of -Omics Techniques to the Study of Endospore Formation

Microbiology spectrum, 2014
Endospore-forming bacteria, with Bacillus subtilis being the prevalent model organism, belong to the phylum Firmicutes. Although the last common ancestor of all Firmicutes is likely to have been an endospore-forming species, not every lineage in the ...

Legionnaires’ Disease Bacterium: A Non-endospore-former

American Journal of Clinical Pathology, 1980
This investigation was done to determine whether dipicolinic acid was present in the Legionnaires' disease bacterium. A colorimetric assay for dipicolinic acid was done and the results for the bacterium were compared with those obtained for Escherichia coli and Bacillus subtilis. Dipicolinic acid was not detected in the Legionnaires' disease bacterium.

Early Events During Bacterial Endospore Formation

1980
Publisher Summary This chapter has considered sporulation mainly as a problem in the regulation of a complex sequence of events. Until now, progress toward a solution of this problem has been slow. As a result of genetical analysis to know the dimensions of the problem, progress has been made on the biochemical side.

Coccidioides immitis endospores: Phagocytosis by human cells

Mycopathologia, 1978
Phagocytosis of killed endospores by glass adherent peripheral human mononuclear cells was studied. Phagocytosis continued through 30 minutes of incubation. No difference in rates of ingestion could be detected when cells from coccidioidin-reactive and nonreactive subjects were compared although both groups ingested endospores more avidly than latex ...
