You have been asked to consult for a biotech company that is seeking to understand why some fungi can live in very extreme environments, such as the high temperatures inside naturally occurring hot springs. The company has isolated two different fungal species, F. cattoriae and W. gravinius, both of which can grow at temperatures exceeding 95°C. The company has determined the following things about these fungal species (see attached image)
By sequencing and examining their genomes, the biotech company hopes to understand why these species can live in extreme environments. However, the company only has the resources to sequence one genome, and would like your input as to which species should be sequenced and whether you believe a shotgun strategy will work in this case.
What is one distinct feature of fungi that could be exploited for antibiotic therapy?

- In 1971, Dr. Akira Endo, working at the Sankyo company in Tokyo speculated that fungi not only contained antibiotics but also inhibitors of other processes such as cholesterol metabolism. Over a period of several years, he screened more than 6,000 fungal cultures until a positive result emerged. This compound, which was named compactin, came from the blue-green mold Penicillium citrinum Pen-5 that was isolated from a rice sample collected at a grain shop in Kyoto. Based on biochemical assays, compactin is the first known statin. 1. The original kinetics data for compactin inhibition of HMG-CoA reductase enzyme that was published by Dr. Endo in 1976 is shown on the right. a) Determine the Km and Vmax values for enzymatic activity.

- How do the authors of the study interpret the information shown in Figure 3? (Choose one.) Group of answer choices The speed (number of days) at which fig saplings die from wilting disease is much faster when the saplings are inoculated with two species of fungi at the same time, compared to only one of the species. The number of days which saplings survive is significantly longer when fig saplings are inoculated with C. ficicola and F. kuroshium at the same time, compared to just inoculated with C. ficicola. There were significantly higher densities of C. ficicola than of F. kuroshium found in plants suffering from fig wilt disease. The number of saplings dying from fig wilt disease was significantly higher in plants inoculated with C. ficicola than in plants inoculated with F. kuroshium plus C. ficicola.arrow_forwardDescribe the process of host: bacteria recognition, attachment and infection for Rhizobium and legumes.
