relying on features such as morphology‚ arrangements and biochemical reactions. It was done in succession with each step complimenting the other. At the end of the experiment three microorganisms Bacillus azotoformans‚ Staphylococcus aureus‚ and Escherichia coli was identified and one result was inconclusive. The focus of this paper will be on the description of the just one of the three bacteria and some of its effects on humans. The first test done was a differential stain (gram stain) to determine

particularly B. methylotrophicus-SCS2012 exhibited strong antibacterial activity against Streptococcus agalactae‚ Bacillus cereus‚ Escherichia coli‚ Shigella sonnei and Shigella dysenteriae with the zone of inhibition range 28.33 to 32.16 mm at 100μg/disc. Minimum inhibitory concentration (MIC) of the extract against Streptococcus agalactae‚ Bacillus cereus‚ Escherichia coli‚ Shigella sonnei and Shigella dysenteriae was found to be 156‚ 156‚ 312‚ 312 and 625μg/ml respectively.

INTRODUCTION Cassia fistula Linn. (Leguminosae) is a very common plant and is widely known for its medicinal properties. In the Indian literature‚ this plant has been described to be useful against skin diseases‚ liver troubles‚ tuberculous glands and its use in the treatment of rheumatism‚ hematemesis‚ pruritus‚ leucoderma‚ and diabetes.[1‚2] Besides‚ it has been found to exhibit anti-inflammatory and hypoglycemic activity and widely used as a mild laxative suitable for children and pregnant women

Maura Gongora 12th December‚ 2014 MCB 3020L- Section 018 Unknown #16 Abstract This report contains the background information on gram positive and gram negative bacteria‚ which will aid in understanding the use of specific laboratory experiments to distinguish between the two types of bacteria. Included are the materials and methods used to identify the gram positive and gram negative bacteria and methods which also differentiate between microbes of each group. The implications of the methods of

SUMMARY : GOLDEN RICE One of the applications of recombinant DNA technology in enriched foods field is golden rice. The organism used is daffodil or maize‚ bacteria Erwinia uredovora and Escherichia coli. The insertion of phytoene synthase (psy) gene from daffodil or maize and phytoene desaturase (crt I) from Erwinia uredovora into rice genome reintroduced carotenoid biosynthetic pathway in the endosperm that was absent before. This gives the ability of making β-carotene (precursor of Vitamin A)

Today‚ certain antibiotics are used in fighting certain diseases caused by pathogenic bacteria such as Salmonella enterica and Escherichia coli. However‚ due to the improper usage of these antibiotics and the increasing antibiotic resistance of the bacteria‚ a lot of the medicines commonly used before to fight the same bacteria are now considered ineffective and because of it‚ scientists try to find ways such as discovering new antibiotics or recommending to the citizens some procedures and ways

ABSTRACT The aim of this study was to investigate the activity of (28%) ethanolic extract propolis (EEP) of [Bazian‚ Pshdar‚ Sharbazher‚ Khormal‚ Kanakawa and Sulaimani (city center)] against (Staphylococcus aureus‚ Staphylococcus epidermidis‚ Escherichia coli‚ Pseudomonas aerugenosa‚ Klebsiella pneumoniae‚ Proteus mirabilis and yeast Candida albicans). Two methods were employed for propolis activity evaluation; firstly by agar well diffusion method using 40µl of propolis extracts and ethanol 70%

This experiment worked with enteric bacteria which are members of the Enterobacteriaceae and live in the intestinal tract (Willey et al.‚ 2014). Also found in Willey et al (2014) is some characteristics of enterics such as they all degrade sugars by
