Grams staining method and reliability of this method. According to me‚ Grams staining process is a simple technique that assists in recognition of etiological agent and therefore can be called as one of the most significant staining practices in microbiology. Though‚ Gram is concerned that the staining process developed by him is imperfect because not all bacteria can be stained by it‚ but in my opinion‚ when we pour ethanol over the slide to wash away the dye then only definite bacteria can retain

CHAPTER I INTRODUCTION 1.1 Background Food is one of human sources of calorie‚ protein‚ fats‚ and nutrition. Yet‚ because of the highly nutritious content‚ food is susceptible to growth of microorganisms. By the presence of microorganisms in food‚ the food is more likely to have shorter shelf life. Thus‚ mostly it is resolved by the addition of antimicrobial substances to food‚ such as condiments and preservatives. Condiments and preservatives could inhibit the growth of microorganisms

primary focus of this lab was on microscopy and simple stains. Crystal violet and Carbol fuchsine‚ simple staining components‚ were used to stain the slide in order to see the different microbes in order to determine their cellular shape and identify unknown ones by comparing. Introduction Bacterial cells are usually colorless because cytoplasm‚ for the most part‚ is transparent. Since the bacteria are colorless‚ it is almost essential to add a stain to make the bacteria more visible. Once stained

Biology was fascinated me tremendously particularly when I was introduced to field of microbiology. I used to wonder how these primitive microbes grow and communicate with each other. Theoretical knowledge of microbiology grabbed my attention and made me curious about these tiny microbes which we cannot be seen through our naked eyes. Therefore I decided to pursue my higher studies and specialisation in microbiology. I started my graduation

Themes of W.H. Auden’s "The Unknown Citizen" Conformity and Anonymity in the Modern World "Social Security Number? Birth date? Nine digit telephone number starting with area code? Mother’s Maiden Name?" In many ways‚ we are simply faceless numbers to modern society‚ not individuals with feelings and emotions and dreams. W.H. Auden‚ a well-known English poet and dramatist‚ discusses this important theme in his poem "An Unknown Soldier." Auden‚ being a modernist‚ is concerned with this modern idea

Pure and impure solids were tested to see what affect pureness/impureness had on a melting point. Background: The melting point of a solid can be used to determine the purity of the solid. Pure samples usually have
