Yellow pigmented colonies of Pseudomonas sp. on Mueller-Hinton agar. Cultivation 72 hours, 28°C.
Pseudomonas species are widespread in nature. The members of the genus demonstrate a great deal of metabolic diversity,
and consequently are able to colonise a wide range of niches. Their ease of culture in vitro and availability of an increasing number of Pseudomonas strain genome sequences has made
the genus an excellent focus for scientific research. Pseudomonas have the ability to metabolise a variety of diverse nutrients. Combined with the ability to form biofilms, they are thus
able to survive in a variety of unexpected places. A simple carbon source, such as soap residue or cap liner-adhesives is a suitable place for them to thrive.
Most Pseudomonas spp. are naturally resistant to penicillin and the majority of related beta-lactam antibiotics.
