Biotechnology and probiotic GOS (Galacto-oligo-saccharides) INTRODUCTION What are Prebiotics? Prebiotics are commonly defined as non- digestible polysaccharides and oligosaccharides. These prebiotics enhance the growth of beneficial bacteria like lactic acid bacteria in intestinal tract and also exert antagonistic property against some other species like salmonella sp. or E. coli. Some scientist also defined other properties of prebiotics; which includes resistance to gastric activity,…

around the disc were measured and sensitivity and resistance of strains were determined and then results were compared with CLSI standard table.20 In each experiment, a disc containing the solvent dimethyl sulfoxide (DMSO) 10% was determined as a negative control and a disc containing Vancomaycin 30 μg/disc and Ciprofloxacin 5 μg/disc standard positive control was used as an antibiotic. The tests were repeated three times and the results were presented in the…

difference between gram negative and gram positive bacterium. This is important when doing gram staining experiments. It also looks at the importance of microbiology. DIFFERENCES OF GRAM NEGATIVE AND GRAM POSITIVE BACTERIUM There are notable differences between the gram negative and gram positive bacterium. Gram negative bacterium is surrounded by a thin peptidoglycan cell wall while Gram positive has a thick layer of peptidoglycan. The peptidoglycan around the gram negative is about 8-10 mm…

trillion of US dollars a year (Pugh). We will also have to use the negative income tax system. A negative income tax will tax the first $35,000 of additional income by 50%. People that are making an additional $35,000, will have an offset in paying taxes and will not be affected by the program (Pugh). Based on the income levels of the 2010 census, providing $17,500 to citizens will only cost the government $1.9 trillion dollars with the negative income tax in effect ("Annual Social and Economic…

and I were given unknown number 3 in the laboratory. After performing various tests over the course of a few weeks on our unknown, we came to the conclusion that our unknown organism is Klebsiella pneumoniae (K. pneumoniae). K. pneumoniae is a gram negative bacillus shaped microorganism. We observed that K. pneumoniae is a nonmotile organism. We performed multiple tests on our unknown culture, therefore we are very confident that it is correctly identified. We identified that K. pneumoniae is…

reagent in the nitrate broth to see if the color would change. After doing every experiment, it appeared that the nitrate color was red and the citric agar turned blue while we identified our unknown bacterium as Enterobacter cloacae, a clinically gram negative, facultative-anaerobic, rod shaped and motile bacterium. E. cloacae infections can include bacteremia, lower respiratory tract infections, skin and soft-tissue infections, urinary tract infections (UTIs), endocarditis, intra-abdominal…

Discussion: The isolate studied was tested for innate antibiotic function on the following media: AC, LB, and 10% TSA. The ESKAPE relative strain that presented a response to the isolate was B.subtilis. In all cases except for that of LB, the isolate showed antibiotic qualities towards B.subtilis by presenting a zone of clearance on AC and 10% TSA media. This behavior is shown in Figures 4, 5, and 6.In the case with LB, B.subtilis inhibited the growth of the isolate as depicted by the empty…

Gathered from the data, it seems that commercial products are more effective than natural remedies; natural remedies made little if no contribution in inhibiting bacteria. This result however, does not signify that natural remedies are inadequate at inhibiting bacteria. It reflects that natural remedies are ineffective in inhibiting gram-positive bacteria. First natural product: Saliva for instance, is one of the body’s many defence mechanisms. Its main function is to prevent adhesion of…

López, C. Sánchez, R. Batlle, and C. Nerín from Spain in 2005, they conducted the antimicrobial activity of clove on several gram negative bacterium E. Coli, Yersinia enterocolitica,Salmonella choleraesuis, Pseudomonas aeruginosa, and several gram positive bacterium, S.aureus, Bacillus cereus, Entero faecalis, and Listeria monocytogenes. The clove essential oil was supplied by ARTIBAL…

differentiates between a Gram-positive and Gram-negative microorganism. This is done in four steps. The microorganism was stained with iodine, crystal violet, alcohol and acetone, and safranin. Iodine was used first as it acts as a mordant. It forms an insoluble complex by binding with the primary stain. It is then stained with crystal violet. Alcohol and acetone acts as a decolorizer. A distinct feature between both Gram positive and Gram negative is the thickness of their peptidoglycan. A…
