Description

Fungi influence our life in many ways. The parasitic forms cause serious diseases in crop plants and have been brought about important changes in the history of some countries. They are both beneficial and harmful to mankind Useful activities:-Fungi, like many saprophytic bacteria are scavengers which are responsible for the decomposition of dead bodies of plants and animals and of their wastes. Through these activities they aid in converting complex substance into simple forms, and this ensure continuing soil fertility. Specific bacteria which act on soil is Nitrosomnas (1)Nitrococcus:-Oxidizes NH3 to Nitrite with large energy and nitrites are converted into nitrates by Nitrobecter (2)Industrial uses:- They are the sources of gallic acid gluconic and, pencillin, ethyl alcohol etc?Which are commerciallyvary important. (3)Fungi as food:--E.g. Mushrooms and morels. These are edible and used as vegetables (4)Food yeast:-It is rich in vitamins e.g. thiamin, nicotinic acid, riboflavin and amino-benzoic acid. (5)Fungi and food processing:-Sp.ofPencillium and Aspergillus are employed in processing of certain food products, baking an chese industry. In bread baking Saccharmycescerevisiae is responsible for alcoholic fermentation by which alcohol and C02 forms is evaporated and the bread shows uniform spongy texture. (6)Fungi in medicine:-Number of Fungi are used as medicines Antibiotics:-These are chemical substances synthesized by living organisms which have capacity to inhabit the growth of metabolic activities of other organisms PennicilliumCitrinum:-Produces citrinin P.nottatum:-Pencillin B and Penicillin P.notatum:-Notatin Chaetomium.Cheatomin.

Is This Answer Correct ? 95 Yes 21 No R Fungi act as natural decomposer acting on dead and decaying substances. Some fungi is commercially utilize for fermentation in baking and brewing industry. Antibiotic Penicillium is extracted from Penicilliumnotatum and Ashby gosypii a filamentous yeast is used in the production of vitamin riboflavin. What is this?

Problem: You want to clone a cDNA into an expression vector so you can make large amounts of the protein in E. coli. The cDNA is flanked by BamHI sites and you plan to insert it at the BamHI site in the vector. The manual recommends that you cleave the vector DNA and then treat it with alkaline phosphatase to remove the 5' phosphates. The next step is to mix the treated vector with the BamHIcut cDNA fragment and incubate with DNA ligase. After ligation the DNA is mixed with bacterial cells that have been treated to make them competent to take up DNA. Finally, the mixture is spread unto culture dishes with a solid growth medium that contains an antibiotic that kills all cells that have not taken up the vector. The vector allows cells to survive because it carries a gene for resistance to the antibiotic. The cloning manual also suggests four controls: Control 1: plate bacterial cells that have not been exposed to any vector onto the culture dishes. Control 2: Plate cells that have been transformed with the vector that has not been cut. Control 3: Plate cells that have been transformed with vector that has been cut (but not treated with alkaline phosphatase) and then incubated with DNA ligase (in the absence of the cDNA fragment). Control 4: Plate cells that have been transformed with vector that has been cut and treated with alkaline phophatase and then incubated with DNA ligase in the absence of the cDNA fragment). - This experiment is discussed: You want to clone a cDNA into an expression vector so you can make large amounts of the protein in E. coli.
