Proteins composting

Recovery of Riologieal Conversion Products Biological conversion produces that can be derived from solid wastes include compost, methane, various proteins and alcohols, and a variety of other intermediate organic compounds. The principal processes that have been used are reported in Table 25-64. Composting and anaerobic digestion, the two most highly developed processes, are considered further. The recovery of gas from landfills is discussed in the portion of this sec tion dealing with ultimate disposal. 

So let us have a closer look at human bone material. You might say that bone is mineralised tissue with a complex compostion. Another description of bone is a fibre-like matrix (mother matrix) in which inorganic salts are imbedded . The fibre-like matrix consists for 90-95% of the protein collagen and for about 5% of other proteins. 

The liquid is very nourishing, and the flesh is a rich source of protein that can be pressed to produce oil. The sap of the tree is fermented to produce an alcoholic drink, the trunks are used as timber, the leaves are plaited to make thatch, and the fibrous layer of the uit is made into coir matting, rope or compost. 

The proximate compostion of the tamarind fruit depends on locality (3) (Table I). The pulp has a low water content and a high level of protein, carbohydrates and minerals. However, (P) reported that the fruit pulp is relatively poor in protein (87.9 g/kg) and oil (25.3 g/kg). 

For the study of drug membrane interactions and of the influence of drug structure and membrane composition, artificial membranes simulating especially mammalian membranes can easily be prepared because of the readiness of phospholipids to form automatically lipid bilayers, i.e. their tendency for self-association in water. The macroscopic structure of dispersions of phospholipids depends on the type of lipids and on the water content. The structure and properties of self-assembled phospholipids in excess water have been described [32], and the mechanism of liposome formation has been reviewed [33]. While the individual components, i.e. the membrane proteins and lipids, are composted of atoms and covalent bonds, their association with each other to produce membrane structures is governed largely by the hydrophobic effect This hydrophobic effect is derived from the structure of water and the interaction of other components with the water structure. Because of their enormous hydrogen-bonding capacity, water molecules adopt a structure in both the liquid and the solid state.
