They are the sex pili. Magnetotactic behaviour thus enables these bacteria to migrate downwards into the oxygen-poor or oxygen-free sediments. Bacteria are simple most primitive organisms. The layer accumulates the excretory substances and protects the bacteria from un-favourable conditions. Capsule layer formation is also responsible for diseases in human and animals because white blood corpuscles are unable to kill the bacteria due to the presence of capsule.

The pili are concerned with attachment of the bacterial cell over the solid surface. The cytoplasm contains organelles living structures and inclusions non-living matter. SASPs are considered to perform at least two important functions: Independent variables generally answer the question What do we change?
