Abstract species are Gram-positive, endospore-forming bacteria having a vital role in the sustainable aquaculture production.Bacillusas gut probiotic significantly enhances growth, immune response, and disease resistance in several aquatic cultured organisms. The supplementation ofBacillusas pond probiotics or...
Endospore, Sporulation— Video (Nice run through of how a vegetative bacterium turns into an endospore) Endosymbiont, History of life — Video (great video on the origin and to some degree the diversity of cellular life, with great visuals; though a bit old, © 1981, it is surprisingly ac...
In order to transform to a virulent form of bacteria, non-encapsulated bacteria must: a. divide. b. be exposed to killed capsulated bacteria. c. be exposed to radioactive phosphorous. d. infect a host.After doing an endospore stain on Bacillu...
(1:1). In addition to these three conditions, a Ctrl—control soil neither inoculated nor sown—was also considered. Pots were prepared at the end of March 2023, watered with 1 L of tap water for each pot every two days, and maintained in an open space under natural climatic conditions...
Germination of the spore in the gastrointestinal tract provides a novel route for heterologous antigen delivery We have evaluated the potential of endospores of the Gram-positive bacterium Bacillus subtilis as an oral vaccine delivery system. The key features of the ... HD Le,HA Hong,SM Cutting...
Initially, the key drivers were: (i) the need of the food industry for a nonpathogenic model bacterium to study the characteristics of endospores, and (ii) the observation, in 1959, that B. subtilis strain 168 could be genetically manipulated by transformation. In the intervening period, B....
An endospore-forming bacterium, strain B16, was isolated from a soil sample and identified as a Bacillus sp. The strain presented remarkable nematotoxic activity against nematode Panagrellus redivivus . The crude extracellular protein extract from culture supernatant of the bacteria killed about 80% ...
An endospore is a dormant, tough, and non-reproductive structure produced by a small number of bacteria from the Firmicute phylum. The primary function of most endospores is to ensure the survival of a bacterium through periods of environmental stress. They are therefore resistant to ultraviolet ...
