Aspergillus

Mucor hiemalis showed high resistance to (Zn, Al) (Table, 37 & Fig. 46). The most interesting, high concentrations of zinc stimulated the growth better than low concentrations (Table 37), Aluminum could stimulate the growth of the fungus slightly in concentrations 100 ppm and 300 ppm respectively. Lower and higher concentrations slightly inhibited the growth but aluminum couldn’t stop the growth of the fungus (Table 37, Fig. 46). While (Mn , Cu and Pb) succeeded to stimulate the growth of Mucor…

Fermentation has been used by mankind for centuries to make useful products such as cheese, breads, yogurts and alcohol beverages. During fermentation, some strains of yeast decompose sugars to derive energy, and in the process they produce ethanol as a waste product. When bread dough is being made, yeast is added to make dough rise. This occurs because the yeast ferments sugar releasing carbon dioxide which causes the dough to rise and creates holes in the bread. This carbon dioxide released…

There are certain animals, plants, fungi, bacteria, and viruses that tolerate and actually thrive in extreme conditions. These organisms are called extremophiles. The word extremophile breaks up into “extreme” and the suffix “phile” literally means “one who loves.” These organisms flourish in the uninhabitable places that vary from extremely high and low temperatures, high pressures, high salinity, the absence of water, and extreme amounts of radiation just to name a few. Many of these…

CHAPTER 1 INTRODUCTION Since time immemorial microorganisms have played a significant role in the life of mankind owing to the production of the myriad enzymes and secondary compounds that they synthesize (Demain 1981). These micro organism live in a highly diverse environment ranging from hot springs to deep ocean sediments. In the hyper diverse environment where one can find a specialized and unique biological niche is the intracellular space between cells of higher plants acts as suite and…
