HYPOTHESIS: Microbial growth will be present in two of the three Agar plates (those containing the food product) due to the suspected presence of microbes‚ whilst the control Agar plate (containing no food products) will remain free of contamination and microbial growth. MATERIALS: - 3x Agar plates - 10g of berry yoghurt - 10g of

Research Plan Title: In vitro Antibacterial Activity of Santol (Sandoricum koet jape) at Different pH of Agar School : Ramon Magsaysay (Cubao) High School School Address: Ermin Garcia St.‚ Cubao Quezon City Research Adviser: Mr. Ryan D. Balandra Statement of the Problem The aim of the study is to identify the effect of different pH level of the Agar plate to the antibacterial activity of Santol (Sandoricum koet jape). Specifically‚ the study will seek for the answer of the question:

2 agar plates divided into 4 equal sections were used for this experiment. Each section was labeled with a number from 1-8. 8 Sterile swabs were used‚ 1 for each surface swab. 8 surfaces in my home were then identified that could serve as a fomite and swabbed with a sterile swab that was dipped in distilled water to moisten it. Surface #1 was the garbage disposal in the kitchen sink. It was swabbed and the microbes transferred to the appropriately labeled section marked #1 of the agar plate. Surface

CHAPTER I INTRODUCTION Background of the Study Mangrove swamps are forested intertidal ecosystems that occupy sediment-rich sheltered tropical coastal environments. By trapping and stabilizing fine sediments‚ mangroves control the quality of marine coastal waters. Aside from maintaining coastal food webs and populations of animals‚ mangroves have an important role in pollution control through their absorptive capacity for organic pollutants and nutrients‚ and they play an important role in storm

Method and it will be discussed in detail below. 2.1.1 Rodac Method The purpose of this Standard Operating Procedure is to describe a program that will adequately measure the efficacy of disinfection of Rooms and equipment in each laboratory‚ RODAC plates can detect the presence or absence of live microorganisms (Longrée and Armbruster 1996). This Method is used to monitor the contamination level of personnel gowns and Personal Protective Equipment (PPE) before or during manufacturing production. The

and starch agar. OBJECTIVES: distinguish between different bacterial species based on colony morphology on agar plates To distinguish the growth characteristics of microorganisms in various differential‚ and selective media. Differentiate bacteria based on their ability to hydrolyze starch. Materials: Plates of EMB‚ Starch and blood agar. Stool sample. Inoculating loop. Bunsen burner. Soil sample. Cotton soap. Skin sample. Gram iodine. Results: Starch agar: Special

bacteria‚ the first step was to isolate each bacterium using streak plate technique. Tryptic Soy Agar (TSA) plate‚ and differential media such as mannitol salt and Eosin methylene blue (EMB) were used for isolation streak technique. This step is imperative because the bacteria need to be separated and isolated before they can be identified. Moreover‚ gram staining was used to understand the basic morphology of these bacteria. As these plates were incubated and grown‚ the presence of two separate bacteria

unknown is. This experiment will also determine if our bacteria is a fermenter of sugars and if it is catalase positive. If the bacteria is a fermenter they will use the sugars to make ATP. If the bacteria is a fermenter of lactose/sucrose the EMB plate we used will “clearly differentiate between the colonies of lactose fermenting and non-fermenting microbes. In the same medium sucrose was also included to differentiate between coliforms that were able to ferment sucrose more rapidly than those that
