5.3.7 Effect of carbon supplements Supplementation of sugars‚ which may act either as carbon sources or inducers‚greatly affect the growth of microorganism. In case of CMCase‚out of the supplemented sugars‚glucose‚sucrose‚maltose‚lactose‚wheatbran and CMC‚ wheat bran show maximum increase in enzyme production. On addition of glucose‚ maltose‚ lactose‚wheat bran and xylan‚ the maltose resulted in an increment in xylanase production (24.96 IU/ml) by SmF. An induction in the enzyme production/activity

Between a hypothesis and a prediction? What kinds of hypotheses are useful for scientific investigations that try to explain the natural world‚ and which are not? Give one or more examples of hypotheses that are and are not scientifically useful. (a.) A scientific theory has two components; a pattern

red growth but no change in the appearance of the medium. This indicates no lactose fermentation‚ however since there is growth‚ this means the bacterium in gram-negative. Mannitol salt agar: This medium was inoculated with both specimens and incubated at 37◦C for 18-24 hours. There being no growth and no change in appearance of the medium for either organism‚ this indicates there was no mannitol fermentation and they do not tolerate

Lesson 02.08 DBA/Module Exam Lesson 02.01: Chemistry of Life · Explain why biological macromolecules are important for everyday life. Cells make large macromolecules by bonding smaller molecules together into chains called polymers (from the Greek polys‚ "many‚" and meris‚ "part"). Polymers are large molecules composed of many identical or similar subunits called monomers. There are four categories of biological macromolecules that provide energy and structure to living organisms and their cells

Introduction: Many different species of bacteria look similar under the microscope and also have the same staining results (ex. Gram stain). To be able to differentiate between the different species‚ one can look at the metabolic differences (fermentation)‚ as well as the environmental condition differences (temperature‚ pH‚ oxygen requirements). Being able to manipulate these conditions in a controlled environment can help to correctly identify the exact bacteria. Different media can be used to

analysis of the fermentative metabolism of glycerol in Escherichia coli through the use of kinetic modeling and metabolic control analysis (MCA) to gain a better understanding of glycerol fermentation and identify key targets for genetic manipulation that could enhance product synthesis. The kinetics of glycerol fermentation in a batch culture was simulated using a dynamic model consisting of mass balances for glycerol‚ ethanol‚ biomass‚ and 11 intracellular metabolites‚ along with the corresponding kinetic

As humans‚ we are the most dominant species in the world. We have the ability to walk upright‚ grasping thumbs‚ and large brains. This helps us to live and be successful on earth. But‚ these advantages we have didn’t happen overnight‚ they occurred during the hominine evolution. The skull‚ neck‚ spiral column‚ hip bones‚ and leg bones of the early hominine species changed shape in ways that later enabled species to walk upright. The evolution of dipedal‚ or two-footed‚ locomotion was very important

differential exercises test the different biochemical processes that the EI can preform. Ex 5-2 oxidation-fermentation test showed the EI to be capable of oxidation and slow fermentation or fermentation only. Ex 5-21 Triple Sugar Iron Agar test showed the EI can ferment glucose and sucrose and/or lactose but is not a sulfur reducer. Ex 5-4 showed the EI is able to preform 2‚3 butanediol fermentation and produce acetoin. Many differential tests that tested the enzymatic properties and activity of the
