You have isolated a new species of bacterium, Mustget caffeinum, from a compost heap that was heavily enriched with coffee grinds. You discover that it can grow using caffeine as its only carbon source but seems to grow better on other carbon sources, You decide to compare its growth rate in defined minimal media (MM) supplemented with either sucrose or caffeine as the sole carbon source. You inoculated M, caffeinum into both MM-caffeine and MM-sucrose at 8 AM. Because this...

Question 9 1 pts You are given a flask with standard liquid media containing a population of S. pombe cells that have a temperature sensitive mutation of a gene that causes complete loss of function of the gene product at the restrictive temperature. The flask had been incubating at the permissive temperature in the dark before it was given to you, and the cells in the flask were replicating asynchronously with respect to the stage of the cell cycle. The...

Title: Development of an Adhesion Assay and Characterization of an Adhesion-Deficient Mutant of Pseudomonas fluorescens RESULTS Bacterial adhesion to sand columns. In the initial column assays with soil-and-sand mixtures, P. fluorescens PfO-1 and E. coli SLH25 had the highest and lowest adhesion values, respectively. Therefore, the sand column assay was optimized to yield the greatest difference in percent adhesion for these two strains. PfO-1 bacteria grown in minimal medium to the logarithmic phase were washed and suspended in either minimal...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
