2) Starter culture is the culture of microorganisms used to inoculate media in fermentation process. For example, in case of production of milk products like curd and cheese, a culture of lactobacillus is used as starter culture to inoculate the milk. 3) Ganoderma is a genus of polypore mushrooms(mushroom species forming fruiting bodies with pores on the underpart.They are populary refrred as shelf or bracket fungis.They are under investigation for use in fields such as bioremediation , medicine, etc. 4) The basic difference between induced mutation, recombinant technology and natural variants lies in the fact that in both induced mutation and recombinant technology a foreign agent is used (mutagenic factors like UV rays, X rays etc. for induced mutation and a foreign host DNA for the recombinant genes) whereas in natural variants the mutations arise naturally and randomly during sex cells formation.
