Potato dextrose agar is a good nutrient agar for mycelia to thrive on which is present in most fungal moulds.1 Standard nutrient agar is a general utility used for non-fastidious microorganisms.2 Aim The aim is to isolate fungi and bacteria colonies from diseased and healthy leaves. Materials and Methods Materials used for the experiment was two of each: standard nutrient agar plate and potato dextrose agar plate. To remove any epiphytic or saprophytic

turn the agar plate over and divide the plate into four quadrants and label the agar plate whether you used the E. coli or B. megaterium and number the quadrants 1 through 4. Please keep in mind that one pair will test the E. coli and Environment 1 or 2‚ and one pair will test B. megaterium and Environment 1 or 2. After‚ you will need to swab the E. coli and B. megaterium on two different nutrient agar plates using a sterile disposable inoculating loop. Remember not to dig in into the agar or the

Chapter 1 The Problem Introduction Today’s technological innovation and medical advances gave birth to formulation of synthetic drugs used to treat respiratory infections‚ urinary tract infections‚ diarrhea‚ arthritis and other diseases. These pharmaceuticals are costly and to a point‚ inaccessible to many Filipinos. These may also pose adverse effects like nausea‚ dyspnea‚ and diarrhea. Researchers are challenged to produce natural medicines‚ which could be lower in cost and more synergistic

source. Simmon’s citrate agar will be prepared by using Oxoid well-prepared Simmon’s citrate agar powder. The Simmon’s citrate agar was prepared by using Oxoid well-prepared Simmon’s citrate agar powder. The preparation was began by suspending 5.75g of the powder in 250 ml of distilled water and mixed thoroughly. The following shows the amount of each composition in 1 litre of Simmon’s citrate agar solution prepared using Simmon’s citrate agar powder. This Simmon’s citrate agar solution was then heated

Little Celleste the cell was in the middle of his meal‚ when he thought for a minute about what he was eating‚ and how it had gotten there. The great Father Cellmas came to his mind‚ so he called out for him because he knew he could solve his answers. Since after all Father Cellmas was the man who knew all the questions you asked him about yourself. Father Cellmas was in the middle of a nap when he heard the yell of a small cell. “I wonder who is calling for me?” Father Cellmas wonders‚ and gets

Data has been presented in the tables‚ charts and drawings herein and reflect the results of microscopic observations as well as the differential tests results on various agars and broth cultures. Although all tests were not conclusive‚ the unknown organism labeled Unknown #11 was found to be a member of the family Enterobacteriacea and Genus Serratia marcescens.

a given sample. It enumerates the number of actual live‚ viable cells in the sample that form colonies on a suitable agar medium. As the optimum medium and conditions varies for one sample to another‚ the colony count methods provide an estimate of the number of viable cells according to the medium employed‚ time and temperature of incubation. Each colony that appears on the agar plate arising either from a clump of cells or from a single cell is referred as a colony forming unit (CFU). The sample

known as "red seaweed." The specific chemical that we are interested in is agar‚ which appears in red seaweed in abundance. When you hear Cereplast and other companies talk about developing bioplastic made from seaweed‚ they really mean that they will be using the chemical agar‚ which is extracted from the seaweed. Fortunately (or unfortunately?) this project won’t have you traipsing out to the ocean to collect seaweed. Agar is used as a food additive in confectionaries‚ desserts‚ beverages‚ icecream

facilitates the handling of large numbers of bacterial clones for classification on a variety of media. METHODS Replica plating. A frequent chore in bacteriological work is the transfer of isolates from one substrate to other selective or indicator agar media. In place of an inoculating needle‚ one might imagine a device consisting of many needle tips in fixed array‚ so that one operation would substitute for repeated transfers with a single needle. The requirements of this design are met by pile
