Agar plates are used as a canvas, while pigmented or fluorescent bacteria and yeasts represent paint. In order to preserve a piece of microbial art after a sufficient incubation, the microbe culture is sealed with epoxy. [2] Microbe species can be artistically chosen for their natural colours to form a palette.

Non-motile bacteria cannot recognize surfaces or aggregate together as easily as motile bacteria. [21] During surface colonization bacteria cells are able to communicate using quorum sensing (QS) products such as N-acyl homoserine lactone (AHL). Once colonization has begun, the biofilm grows by a combination of cell division and recruitment.
About 8% of the shelf with diatomaceous mud has free gases are present in shallow depths. [17] When the gas is released from the sediment, sulfide is released into the water column. T. namibiensis is more prevalent in areas with free gas, suggesting that the presence of suspended sulfide is beneficial to the bacteria.
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
The material can affect the time bacteria can survive on door handles, but more important is the temperature and humidity of the environment. A hospitable environment can allow bacteria to thrive for anywhere from a few hours to a few weeks on a surface. A crucial factor in the bacterial growth and spread is the location of the handle.
The attacks on the family continued, with large posters appearing around town spreading rumors about their 12 year old child. One day in 1977, the husband left the house after receiving a call ...
At low cyclic di-GMP concentration, P. aeruginosa has a free-swimming mode of life. But when cyclic di-GMP levels increase, P. aeruginosa start to establish sessile communities on surfaces. The intracellular concentration of cyclic di-GMP increases within seconds when P. aeruginosa touches a surface ( e.g. : a rock, plastic, host tissues ...
