Example text

There is a covalent bond between heme and an Fe2þ ion and histidine (His). The heme molecule has a high affinity to bind with oxygen. The core of this molecule is Fe2þ-Fe3þ, surrounded by four porphyrin rings. The porphyrin ring is not only present in heme, but it is also appears in chlorophylls of green plant cells. For oxidation and reduction, shifting may occur from Fe2þ to Fe3þ inside the heme in a reversible reaction for oxyhemoglobin or reduced (redox) forms of globins. 1 represents vitamins functioning as coenzymes.

However, the productivity of lipase in solid media (solid-state fermentation) is much higher than liquid media (submerged fermentation). In tray bioreactors, depth of the solid bed influences the productivity extensively. 94 transfer within the solid bed are considered. In the present case study, this parameter was studied by making paper bags of different dimensions. 0 cm, and the corresponding lipase activities and total proteins were evaluated after 72 h of fermentation at 35  C. 5 cm bed depth.

New York: McGraw-Hill; 1986. 3) are well-known biocatalysts participating in the hydrolysis reaction to produce fatty acids and monoacylglycerols from triacylglycerols. The reaction occurs in the watereoil interface. 9 Their usage offers two advantages: first, it helps to omit or reduce environmental pollution caused by their disposal into open spaces. Second, it results in the production of value-added products (such as enzymes) from invaluable sources. Solid-state fermentation (SSF) and submerged fermentation (SmF) are regarded as two suitable fermentation techniques for the production of enzymes, including lipases.
