MILK FABRIC ABSTRACT: The milk fabric is new born fabric. The milk protein fabric moistens skin and it is healthy and bacteriostatic - it is the perfect material to produce underwear and socks‚ pants‚ long-sleeve T’s and jackets also. The important ingredients of milk protein fiber are milk casein proteins‚ which can nourish and lubricate the skin. The milk protein contains the natural humectant factor‚ which can capture the moisture and maintain skin’s moisture to make the skin tender and smooth

bacterium was gram-negative bacilli that did not utilize citrate‚ and the ability to hydrolyze urea using urease. These results indicate that the identity of unknown number 34 is Proteus mirabilis. Introduction Proteus mirabilis is a gram-negative bacillus bacterium. It is found naturally in the human gut flora. However‚ if P. mirabilis comes into contact with the urinary tract‚ urinary tract infections can result. Urinary tract infections caused by P. mirabilis are correlated

[32] have also reported a new alkaline serine protease from Bacillus subtilis DM-04 with highest activity at 45 °C‚ 72 h of incubation and 1.25% (w/v) of beef extract as the most effective factors on protease production. In order to verify the model adequacy‚ optimum conditions for protease yield was performed and

OBSERVATION OF BACTERIAL CELLS VIA MICROSCOPE In this experiment‚ we have learned several basic molecular biology techniques. Here they are; Simple staining: Only one type of dye used for simple staining and it stains all cells the same color. Creating contrast between cell and background to observe cell morphology is aimed. Differential staining: A differential stain uses more than one dye and stains different kinds of organism with different colors. Positive staining: If cell itself is stained

have been injected with genes that allow them to have five times more grain heads than regular rice plants. Also‚ with this easier farming‚ there is more food to feed to hungry or starving populations. Many GMO’s are injected with bacteria called bacillus thuringiensis. Making BT crops makes the plant have more resistance to pests and viruses that could harm the plant. The bacteria injected in it causes insects to resist the plant. But‚ using BT is better than spraying plants with insecticides because

similar in their chemical composition and chemical reactions. Prokaryotes have peptidoglycan in the cell wall. Prokaryotes are Bacteria that are unicellular. Most Bacteria multiply by binary fission. There are three kinds of bacteria shapes: coccus‚ bacillus and spiral.

The shape appears to be corkscrew in nature and vary in length throughout the sample slide. The length varies but the width seems to be uniform. The color most likely arises from the stain used to allow for better visualization of the organism. The Bacillus sample has no discernable morphology and appears as round ended‚ and cylindrical shaped in nature. The organisms have a black tint which is probably related to the type of statin used for visualization of the organism. Question C Bullet 1 The

GMOs are plants or animals that have undergone a process where scientists alter their genes with DNA from different species of living organisms‚ bacteria‚ or viruses to get desired traits such as resistance to disease or tolerance of pesticides. How do scientists Genetically modify organisms? Genetically modifying organisms works just like an advanced form of cut and paste. During genetic modification‚ DNA is taken from and unrelated plant‚ animal or bacteria and inserted into a different organism

the mold had something in it that inhabited the bacterial growth. Fleming soon called this “mold juice.” He noticed that it was capable of killing a variety of harmful bacteria. These bacteria included streptococcus‚ meningococcal‚ and diphtheria bacillus. In due time trying to extract penicillin-incentive bacteria from penicillin sensitive bacteria; however this soon failed and the process was tried again. The discovery of how this drug was life saving happened from two individuals who let their
