Biofilm print that page


A biofilm is an aggregate of microorganisms in which cells adhere to each other on a surface. These adherent cells are frequently embedded within a self-produced matrix of extracellular polymeric substance (EPS). Biofilm EPS, which is also referred to as slime (although not everything

Microbial fuel cell print that page

A microbial fuel cell ( MFC ) or biological fuel cell is a bio- electrochemical system that drives a current by mimicking bacterial interactions found in nature . Mediator-less MFCs are a more recent development; due to this, factors that affect optimum efficiency, such as the strain

Bacterial cell structure print that page

Perhaps the most elemental structural property of bacteria is cell morphology (shape). Typical examples include: coccus (spherical) bacillus (rod-like) spirillum (spiral) filamentous Cell shape is generally characteristic of a given bacterial species, but can vary depending on growth

Evolutionary history of life print that page


The evolutionary history of life on Earth traces the processes by which living and fossil organisms evolved. It stretches from the origin of life on Earth, thought to be over 3,500 million years ago , to the present day. The similarities between all present day organisms indicate the presence

Escherichia coli print that page


A strain of E. coli is a sub-group within the species that has unique characteristics that distinguish it from other E. coli strains. These differences are often detectable only on the molecular level; however, they may result in changes to the physiology or lifecycle of the bacterium. For
