Biology science research laboratory Report - try Example quaternity disinfectant cleanable (concentrate), 2007). It may write out in arduous pack indicated as Pseudomonacidal, Staphylocidal, Salmonellacidal, Bactericidal, Fungicidal, Virucidal, and mildewstatic disinfectant (LYSOL strike out I.C. quaternate antimicrobic washed (concentrate), 2007). It is overly cat valiumly know as decontaminant in almost every spheres where microorganisms are non welcome (LYSOL brand name I.C. Quaternary antimicrobic Cleaner (concentrate), 2007). Its participating ingredients are Didecyl dimethyl ammonium ion chloride, 10.14%, and n-Alykl (C14 50%, C12 40%, C16 10%) dimethyl benzyl radical ammonium chloride , 6.76%. Its trifling ingredients are 83.10% (LYSOL shuffle I.C. Quaternary disinfectant Cleaner (concentrate), 2007. fit to Reckitt Benckiser the company of professionals that merchandise Lysol, the product has been frame to be legal at imperative transmission by eradica tion of cat valium microorganisms that have been the aetiological agents of gracious and living creature diseases such as colds diarrhea, Rhinovirus (LYSOL stigma I.C. Quaternary germicide Cleaner (concentrate), 2007). Thus, Lysol is anti-bacterial, anti-fungal, and anti-virus agent (LYSOL tick off I.C. Quaternary Disinfectant Cleaner (concentrate), 2007). However, its capacity of mortifying growth of genus genus genus genus genus genus Serratia marcescens must be tested.Serratia marcescens is the common strain of bacteria normally utilize as laboratory experimental subjects. This bacterial strain has a characteristic addiction color of red, and has been piece to be selectively pathogenic to human beings (Owens & McGowan, 1999). As pathogenic organisms, they are unresolved of causing pathogenic diseases (Owens & McGowan, 1999). They may overly be contaminants of materials (Owens & McGowan, 1999). However, they keister be easy eradicated by somatic contact with Lysol as proven by the professionals of Reckitt Benckiser company (LYSOL Brand I.C. Quaternary Disinfectant Cleaner (concentrate), 2007). argumentation of the question Does Lysol repress the growth of Serratia marcescens HypothesisHo Lysol does not inhibit growth of Serratia marcescens.Description of investigate The hold in set-up represent of 2 Petri dishes of nutrient nutrient agar move with Serratia marcescens marked O% Lysol, and the experimental Set-up make up of 10 Petri dishes of agar streamleted with Serratia marcescens marked vitamin C%, 50%, 25%, 12.5%, and 6.25% Lysol. In addition, 12 small musical composition dots, and 50 ml per concentration of Lysol was prepared.PredictionIf a solution contains superior concentration of Lysol, therefore there bequeathing be great zone of prohibition on a plate streaked with Serratia marcescens, and dismay concentrations will not show, if at all, zones of inhibition. substance of Prediction The issue of zones of inhibition s would reveal Lysols set up on Serratia marcescens, whether at gamy concentration or at funky concentration. Methods and Materials a) Independent variable star i) Lysol, Serratia marcescens, and 1 week were the strong-minded variables. ii) Lysol was prepared at 100%, 50%, 25%, 12.5%, and 6.25% concentrations, tour Serratia marcescens was streak on 12 agar plates. iii) These were elect to determine at what concentration of Lysol will there be greater or lower zones of inhibitions on Serratia marcescens as streaked on 12 agar plates. iv) 0% Lysol was indicated for the control group. b) Dependent variables i) The zones
