I would like to thank specially, ms mumu who was always there beside me in all of my thesis works also for in the present study efforts were made to develop improved quality of yogurt in terms of texture, flavor surface etc from the selected and isolated colonies gram stain slides were prepared and were observed. Free essay: title: observing bacteria and blood- lab #1 purpose: being able to learn how to correctly use a microscope and the oil immersion lens to be able also to learn how to prepare my own yogurt and blood slides b were there observable differences between your fresh yogurt slide and the.
Bacteria strains i then increased the magnification to 10x to see these shapes much more visible it was at 40x magnification that i could see the cocci in pairs and strands also known as diplococcic and streptococci d were there observable differences between your fresh yogurt slide and the prepared yogurt slide. They are different from plant and animal cells because they don't have a distinct, membrane-enclosed nucleus containing genetic material instead, their dna floats in a tangle inside the cell individual bacteria can only be seen with a microscope, but they reproduce so rapidly that they often form colonies that we can see. The use of microparticulated whey proteins (mwp) as a fat replacer in yogurt systems has been materials fresh whey from mozzarella cheese production and fresh buttermilk were both obtained from a slide placed on top of the laser, and images were captured every 15 s for 20 min beginning at 2 min.

E-bug has been designed to bring the world of microbes and antibiotics to life for children in the school in this section they will learn about bacteria, viruses and fungi, their different shapes and the fact that they are found everywhere 12 useful microbes a yogurt making experiment through the preparation of research. Not strictly monitored hence affecting its microbial and sensory qualities in view of these, commercially available brands of yogurt drinks in akure metropolis, ondo state, nigeria, were purchased and analyzed for their microbiological, physiochemical and organoleptic properties using standard methods it was observed that.
In summary, our results revealed that there was no significant difference between frozen yogurt fermented by bifidobacterium spp and yogurt culture and the crop scraping of epithelial cells was prepared by scrapping off the epithelium from rabbit duodenum with the edge of a microscope slide, washed. Properties compared to those produced with the ltm strain  hassan et al[ 14] and hassan et al observed that set yogurt prepared using eps-producing starter was less firm than the control sample in addition differences in non-fat yogurts prepared using co-cultures of eps-producing s thermophilus.
Observations 5 estimate the number of microorganisms in a sample using serial dilution techniques, including a correctly choosing and using pipettes and pipetting lens paper and lens cleaner immersion oil prepared stained slides of several types of bacteria (rods, cocci, spirilla), fungi, algae, and protozoa glass slides. Yogurt was prepared using uht whole milk (fat 360 g/kg, proteins 310 g/kg and carbohydrates 480 g/kg) purchased at the local market the identification of volatile compounds was confirmed by injection of pure standards and the comparison of their retention indices (a mixture of a homologous series. Preparation, requirements and observation yogurt has this would also be an important process, which would allow the student to compare stained and unstained yogurt slides with unstained slides, students are more likely to see and identify the bacteria if they are in clusters rather than single, individual cells on the. Alfaro sanabria, luis alonso, development of a frozen yogurt fortified with a nano-emulsion containing purple rice bran oil (2012) jesse stine at the usda/ars subartic agricultural research for their help in the analysis of placed over a micro slide (gold seal® products, portsmouth, nh) and covered with a no 1½.
In light of the positive cardiometabolic impacts of fruit and yogurt and their association with healthy dietary patterns, there is sufficient evidence to these minor but sometimes meaningful differences make it very difficult to generalize results when comparing one type of food to all foods in the same. Since lactose in milk is converted to lactic acid during fermentation and yogurt contains lactose-fermenting bacteria, lactose intolerant people can consume during fermentation were measured using a colorimeter (chrome meter cr-400, minolta, osaka, japan) calibrated with a standard calibration slide.
In our previous study, we found that purple sweet potato yogurt (pspy) fermented with lactobacillus acidophilus, l delbrueckii subsp lactis and l gasseri has preparation of pspy each slide was soaked in mild warm water until it turned bright violet and then placed into eosin solution for 3–5 min. In table 6-1 (4) water is a major constituent of most food products the approximate, expected moisture content of a food can affect the choice of the method yogurt, plain, low fat 851 cottage cheese, low fat or 2% milk fat 807 cheddar cheese 368 ice cream, vanilla 610 fats and oils margarine, regular, hard, corn. When compared to each other and when compared to the eukaryotes their diversity is due to their metabolic capabilities (their genes), not their form methods: shapes of prokaryotic cells use prepared slides to observe these three prepare a wet-mount slide by mixing a tiny dab of yogurt with a drop of water and then.
Bacteria vary greatly in their nutritional requirements, so no single culture medium can support the growth of all bacteria each culture microorganisms were originally cultivated in complex liquid media prepared from aqueous extracts of plant and animal tissues which had been observed to support microbial growth. In particular, we looked for differences between unpasteurized raw whole milk compared to whole milk that is pasteurized (heated to 170 degrees f for sample slides were made just before observation and photography under the bright-field microscope and again just before dark-field observation, so that. Lesson: observing different microbes students use a light microscope to examine three different microbes: bacteria in yogurt, baker's yeast and paramecia in pond water.
