In the endogenous respiration concept the biodegradable fraction of X OHO is regarded as a homogenous substrate that undergoes self-destruction in the absence of external substrate. The degradation process of X OHO is modelled with Eq. (4) and Eq.xperimental evidence for the validity of the endogenous respiration model comes from Marais and Ekama (1976) . Using the OUR method, the value of b OHO was found to be 0.24 d â1 and independent from SRT in the range of 2.5â30 days. Similar results were obtained by van Haandel et al.
The taste buds of the tongue occur within papillae (foliate, fungiform, and vallate) present in the stratified squamous epithelium of the tongue. The taste buds consist of basal cells (near the basal lamina), supporting cells, and gustatory cells (sensory or neuroepithelial cells).The gustatory cells, which can be distinguished from supporting cells with a specific staining only, have microvilli at their apical ends extending in the taste pore.he taste buds of the tongue occur within papillae (foliate, fungiform, and vallate) present in the stratified squamous epithelium of the tongue.

Differentiation of Keratinocytes: Keratinocyte stem cells reside in the basal layer of the epidermis, which is the lowest layer of the stratified epithelia. These cells divide to give rise to transient amplifying cells which divide further, and differentiate, as they move upwards in the epidermis.quamous keratinocytes are also found in the mucosa of the mouth and esophagus, as well as the corneal, conjunctival, and genital epithelia. These cells are responsible for forming tight junctions with the nerves of the skin. They also keep Langerhans cells of the epidermis, and lymphocytes of the dermis, in place.
