days. It did not take much of a leap to discover leavened (raised) bread when yeast was accidentally introduced to the paste. Instead of waiting for fortuitous circumstances to leaven their bread‚ people found that they could save a piece of dough from a batch of bread to put into the next day’s dough. This was the origin of sour-dough‚ a process still used today. In Egypt‚ around 1000 BC‚ inquiring minds isolated yeast and were able to introduce the culture directly to their breads. Also a new strain

Included among the fungi‚ along with mushrooms‚ are molds‚ mildews‚ rusts‚ smuts‚ truffles‚ and yeasts. Toadstool is another name for mushroom. Some people use the name toadstool only when referring to poisonous mushrooms‚ but botanists make no such distinction. A general scientific term for fungi is mycota‚ from the Greek word for mushroom‚ mykes

GENETİCS DATE OF EXPERIMENT: 02.03.2011 ABSTRACT In this experiment‚the cell growth of yeast is measured by using spectrophotometer and hemocytometer.We learnt how specthophotometer and hemocytometer use and also we learnt qualifications of hemocytometer and spectrophotometer.Serial dilution was used for this experiment and it was very important.Because of the serial dilution‚we measured the number of yeast cells. The graph of growth curve was drawn and bacterial life cycle was understood with the

solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then it will break down the peroxide faster because yeast tends to rise faster as the temperature increases. Some constants in this lab are: the 10 mL of peroxide‚ the 190 mL of water‚ the same timer‚ the same sheet of filter paper and the

be the pinnacle of craftsmanship and skill. It is a bread that is quite tricky to make and even more tricky to do well. This is because every aspect of the bread is from scratch‚ most importantly the yeast used in its production. When making sourdough‚ the baker must grow and cultivate their own yeast cultures in order to make the bread rise. It is through this process that more control is given‚ and this allows for better quality bread. This is the essence of making sourdough. The idea that the quality
