Bacterial Cell Surface Tension Attachment and Implications for Article - 1
Bacterial Cell Surface Tension Attachment and Implications for Bioremediation - Article Example There was no significant relationship between the culturing of the bacteria with their attachment to the different material that was being tested. The environments under which the bacterial species were cultured had the significant influence on the level of attachment of different bacterial species to various surfaces. These results present essentially in seeking to establish the variance of species adherence to hexadecane. The attachment of microbial cells to solids and hydrophobic liquids is an important prerequisite in the degradation of chemicals that are recalcitrant because of extremely low solubility. Bacterial adsorption at interfaces is a physical and chemical process that, for the majority of micro-organisms, does not involve the expenditure of metabolic energy. The attachment process involves non-specific interactions between the cell surface, the solid or hydrophobic liquid and the bulk liquid phase(Abbasnezhad et al. 2011). Many factors influence bacterial attachment at solid/liquid and liquid/liquid interfaces. Environmental factors such as pH, temperature and the presence of cations, anions and organic molecules in the bulk liquid phase all directly affect the attachment process, as does the nature of the solid or the hydrophobic liquid(Mceldowney & Fletcher 1986). Microbial factors are equally important in determining the extent of bacterial attachment to surfaces, and the characterist ics of the cell surface have a considerable impact on attachment. Microbial cell surfaces are complex and consist of a variety of macromolecules, which vary with the microbial type. The macromolecular composition of bacterial cell surfaces, also, differs with growth substrate, growth phase, and growth rate. Such variations alter the charge and hydrophobic characteristics of bacterial surfaces (Rosenberg et al. 1980).Ã Ã
