Paenibacillus macerans

Paenibacillus macerans is a diazotroph bacterium found in soil and plants capable of nitrogen fixation and fermentation. This bacteria was originally discovered in 1905 by an Austrian biologist named Schardinger and thought to be a bacillus.

Paenibacillus macerans is a part of the Paenibacillaceae family which are facultative anaerobes. It is gram-variable, being gram-positive or gram-negative rods. Does not have a capsule and has peritrichous flagella for movement. It does form ellipsoidal, terminal, or subterminal spores which may last in the soil for many years.

P. macerans can be grown in the lab on a nurtient agar with a slightly acidic pH around 5. Optimal growth temperature is 30 °C. Also is able to grow in 5% NaCl making it a halotolerant bacteria.

P. macerans has been shown to have some of the broadest metabolic capabilities of any of the Paenibacillus genus. It is able to ferment hexoses, deoxyhexoses, pentoses, cellulose, hemicellulose and glycerol under anaerobic conditions. The high fermentation rates of glycerol makes this an important organism in the study of fuel and chemical production. P. Macerans also produces a significant amount of histamines which may cause allergies in some individuals if ingested. This bacterium is a facultative anaerobe capable of nitrogen fixation so in the absence of oxygen it is able to convert nitrogen gas to ammonia which is more easily used by plant.
