Bacillus Literature Reviews Samples For Students

Introduction

Bacteria are the very first life forms in the history of our planet. Since the beginning they were exposed to extreme changes of temperature, pressure, pH and nutrients; hence, to survive, they had to adapt themselves. One strategy of survival is to go into suspension or dormancy, by converting themselves into a seed form or spores. When conditions become normal, these spores germinate back to vegetative form. This property is also seen in pathogenic bacteria that infect higher animals such as humans. One such group of bacteria is from the Genus Bacillus.When exposed to stress, these bacteria go into dormancy ...

Bacillus thuringiensis is a gram-positive, spore-forming soil bacterium. It can be used as a biological pesticide, since it produces specific parasporal crystalline inclusions that have proven to be toxic for some widespread insect pests. That is why currently the main aim of the researches concerning these bacteria is creation and examination of new more effective strains to be used for control of the insect pest populations and development of insect resistant plants. The restriction enzymes are widely used for genome analysis of the different strains.
Valicente and da Silva have used restriction enzymes in their study to investigate the genetic ...

In addition to the direct physical manifestation of swarm phenotype –increased length and number of flagella, swarm cells often produce wetting agent, usually a surface of some type, for instance, the surface in Serrtia (serrwettins) and Bacillus (surfcatin) (White, 2006). In both cases loss of surfactant dramatically decreases swearing proficiency in Bacillus as well as strains of E. Coli do not make surfactants, which is probably why they are such picky swimmers. Surfactants act mainly to maintain surface wetness, which in turn allows cells to swim in every shallow layer of fluid on the surface.
Research findings indicate that ...
