Microbial Diversity and Ubiquity Microorganisms are microscopic organisms that are so small that that they can only be visualized by the aid of a compound-brightfield microscope. While we generally cannot see individual microorganisms with the naked eye‚ they are present in virtually every habitat known to man. Microorganisms can be prokaryotic—the bacteria or eukaryotic—the algae‚ protozoa or fungi. While viruses are acellular they are also studied in the scope of microbiology because

Biology 1003 - Cells: Size‚ Structure and Microscopy Introduction What is life? What are the key factors that biologists have defined that apply to every single organism on the planet? In the 17th century‚ due to the amazing advancement of the microscope‚ biologists created a theory to differentiate the living from the non-living called the cell theory. One concept from the theory is that all living organisms are composed of one or more cells. The importance of studying cells is akin to the

Saccharomyces cerevisiae R-8 exhibited the best attributes for ethanol production by being highly flocculent‚ tolerant to v o v 6 - 12% ( /V) ethanol‚ fermentatively active at 37 - 42 C and fermented 40% ( /V) glucose. S. cerevisiae T-7 and S.cerevisiae R-2 showed rapid fermentative activity on maltose by liberating 150 and 120 µl of CO2 in 6 h‚ respectively.

INTRODUCTION Background of the Study Jackfruit (Artocarpus heterophyllus L) is an evergreen tree that grows up to 10 feet under favorable conditions. They are an important food wherever grown. Archeological findings have revealed that jackfruit were cultivated in India 3000 to 6000 years ago. Jackfruit is widely grown in Bangladesh‚ Burma‚ Sri Lanka‚ Malaysia‚ and Indonesia‚ Philippines‚ Brazil and other tropical countries. It bears fruits that are green or yellow in the exterior when ripe. The

As suggested‚ we performed the enzymatic experiments as described in material and methods. It was observed that CgAKR-1 has activity on acetaldehyde‚ corresponding to 59.2 % of the activity with the standard substrate 2-nitrobenzadehyde. Moreover‚ the enzyme had no activity against acetone (Propanone); the result was included in Table 1. According to Santoro et al. [76]‚ it was not detected acetaldehyde in hemicellulosic hydrolysate‚ which was produced at the same conditions described in the present
