Inactivation of Bacterial Vegetative cells and Endospores with some Chemical Disinfectants January 2007 Project: Research on Biomaterials at Institute of Tissue Banking and Biomaterial Research

bacterial vegetative cells. The bacterial endospores need a staining which can penetrate wall thickness of spore bacteria. A method of endospores staining is Schaeffer Fulton method that used Malachite Green. It is an alkaline substance staining that can staining the spore bacteria.

A normal bacterial cell is known as a vegetative form of a bacterial cell.It can multiply freely when provided with conducive environmental conditions like the provision of nutrients, temperature, water, and oxygen. Spore-forming bacteria are natural contaminants of food raw materials, and sporulation can occur in many environments from farm to fork. In order to characterize and to predict spore formation over time, we developed a model that describes both the kinetics of growth and the differentiation of vegetative cells into spores.

- bacterial smears provide scientists with the means to look at microorganisms - preparing smears disperses bacterial cells on a slide so that individual cells can be visualized under the microscope - preparation of bacterial smears is required for bacterial staining procedures This stain is designed to distinguish vegetative cells of bacteria (active, living cells) from endospores.

Control strategies: inactivation of vegetative cells. Brown (this issue) deals with control of bacterial spores. It should be emphasised that, if spores survive a heat

In prokaryotes, the primary function of the cell wall is to protect the cell from internal turgor pressure caused by the much higher concentrations of proteins, and other molecules inside the cell compared to its external environment. It is the commonest type of reproduction under favorable conditions in which cell divides into two similar daughter cells. During the process, the bacterial chromosomes get attached to the cell membrane and replicates to the bacterial chromosomes.
