Endospores contd Newly formed endospores appear as round, highly refractile cells within the vegetative cell wall, or sporangium Some strains produce autolysins that digest the walls and liberate free endospores The spore protoplast, or core, contains a complete nuclear material, ribosomes, and energy generating components that are enclosed within a modified cytoplasmic membrane.

Some bacteria, notebly those of the genera Bacillus and clostridium, devolope a highly resistant resting phase or endospore, whereby the organism can survive in a dormant state through a long period of starvation or other adverse enviromental condition.

Positioning of LPS molecule The Lipid A head of the molecule inserts into the interior of the membrane The polysaccharide tail of the molecule faces the aqueous environment Where the tail of the molecule inserts into the head there is an accumulation of negative charges such that a magnesium cation is chelated between adjacent LPS molecules This provides the lateral stability for the outer membrane, and explains why treatment of Gramnegative bacteria with a powerful chelating agent.
