What is Paenibacillus sp?
What is Paenibacillus sp?
Paenibacillus is a genus of facultative anaerobic, endospore-forming bacteria, originally included within the genus Bacillus and then reclassified as a separate genus in 1993. polymyxa, which is capable of fixing nitrogen, so is used in agriculture and horticulture, the Paenibacillus sp.
Is Paenibacillus pathogenic?
Pathogenicity. Some Paenibacillus species are known to infect various organisms, including honeybees and the parasite vector Biomphalaria glabrata, and occasionally present as opportunistic infections in humans.
Where is Paenibacillus Glucanolyticus found?
Paenibacillus glucanolyticus, formerly included in the genus Bacillus (24), is a facultatively anaerobic, long and thin rod-shaped bacterium that may be isolated from various soils (25). This organism appears mostly Gram negative and may produce oval spores that swell the sporangia (10).
Is Paenibacillus oxidase positive?
All of these isolates were catalase, oxidase, and Voges-Proskauer positive and nitrate negative, and all produced acid when glycerol, esculin, and maltose were added. The isolates produced variable results for 16 of the 49 biochemical tests; negative reactions were recorded in the remaining 30 assays.
Is Paenibacillus motile?
Flagella are essential for motility on hard agar media. Genome sequencing suggests that Paenibacillus sp. possesses at least two potential organelles for motility: flagella and pili. To determine which might be responsible for motility, we carried out gene disruption.
What is the shape of Paenibacillus Polymyxa?
rod-shaped
P. polymyxa is an anaerobic nitrogen-fixing Gram-positive bacterium that is rod-shaped, 0.6 by 3.0 μm in size, and produces pale colonies on agar [3].
What is the shape of paenibacillus Polymyxa?
Where is Bacillus polymyxa found?
Paenibacillus polymyxa, also known as Bacillus polymyxa, is a Gram-positive bacterium capable of fixing nitrogen. It is found in soil, plant tissues, marine sediments and hot springs. It may have a role in forest ecosystems and potential future applications as a biofertilizer and biocontrol agent in agriculture.
Is paenibacillus Gram-positive or negative?
The genus Paenibacillus is characterized as rod-shaped Gram-positive or Gram-variable endospore forming aerobic or facultatively anaerobic bacteria. Originally derived from a Bacillus, group 3 was proposed by Ash et al.
What kind of disease does Paenibacillus lentimorbus cause?
Paenibacillus popilliae and Paenibacillus lentimorbus are obligate pathogens that cause “milky disease” in scarab larvae in the subfamilies Melolonthinae, Rutelinae, Aphodinae, and Dynastinae ( Klein, 1992; Garczynski and Siegel, 2007; Jurat-Fuentes and Jackson, 2012 ).
How does Paenibacillus popilliae cause Japanese beetle disease?
Paenibacillus popilliae causes a fatal illness called milky disease in Japanese beetle larvae. After ingestion by the larvae, B. popilliae germinates in the gut, begins to multiply, and invades the hemolymph. After about 10 days, a typical milky appearance is observed due to the massive numbers of bacteria.
Why are Paenibacillus larvae used for insect control?
Different variants of B. thuringiensis, Paenibacillus popilliae, Paenibacillus larvae, B. cereus, Lysinibacillus sphaericus, and other related species are pathogenic to insects. The use of these strains for microbial insect control offers the advantage of being safer than the more toxic chemical control agents.
Why is Paenibacillus an opportunistic pathogen in humans?
Paenibacillus species are also opportunistic pathogens in humans, more commonly affecting immunocompromised individuals.
