Is Bacillus polymyxa Gram-positive or negative?
P. polymyxa is a Gram-positive, rod-shaped bacterium [3], that is also motile. It achieves motion via peritrichous flagella [3].
Where can Bacillus polymyxa be 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.
What is the use of Bacillus polymyxa?
Polymyxin B is an antibiotic derived from the bacterium Bacillus polymyxa, primarily used for the treatment of resistant Gram-negative infections. It is a mixture of a number of identical compounds varying in their fatty acid group.
What antibiotic does paenibacillus Polymyxa produce?
Fusaricidins. Fusaricidins produced by P. polymyxa strains are antibiotics in which six amino acids form a cyclic structure, and these compounds are highly active against Gram-positive bacteria and plant pathogenic fungi and oomycetes.
What is paenibacillus Glucanolyticus?
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 B subtilis aerobic or anaerobic?
Even though B. subtilis is still generally considered to be an obligate aerobe, several recent studies have proved that this bacterium is in fact a facultative anaerobe, which is capable of both fermentation and anaerobic respiration with either nitrate or nitrite used as the terminal electron acceptor (19, 20).
Is Bacillus licheniformis Gram-positive?
Bacillus licheniformis is a Gram-positive, endospore-forming, saprophytic organism that occurs in plant and soil (Veith et al., 2004). A taxonomical approach shows that it is closely related to Bacillus subtilis (Lapidus et al., 2002; Xu and Côte, 2003; Rey et al., 2004).
What is Bacillus licheniformis?
B. licheniformis has been used for industrial production of proteases, amylases, antibiotics, and specialty chemicals with no known reports of adverse effects to human health or the environment. The Agency has reviewed three submissions for production of enzymes using genetically modified B. licheniformis.
Where is paenibacillus Glucanolyticus found?
Can paenibacillus grow on MacConkey Agar?
It grew at 50°C as pinpoint colonies after 72 hours of incubation, but did not grow at 65°C or on MacConkey agar. It was non-motile.
