Dec 04, 2012·Enzymatic activities of bioactive washing powder Title: Investigation of the amalyse activity f bioactive washing powder Objective: To investigate the amalyse activity of the two brands of bioactive washing powder – “Super clean” and “Magic power”. Principal: Amalyse can catalyse the breakdown of starch into maltose.
What Are Enzymes in Biological Washing Powder? Most biological laundry detergents contain lipase and protease enzymes, both of which are found in the body. Lipases break down fats and oils, while proteases work to break down protein chains. Their ability to break down these compounds makes them excellent for stain removal.
Feb 05, 2015·On further investigation I found out that he washed most of his clothes on a quick wash and that he overfilled the washing machine with clothes. If you think logically about this, his clothes were not being given sufficient time or space to be thoroughly washed and rinsed! ... The problem with non-biological washing powder is that is simply ...
The control of all the normal activities of a bacterium depends upon its single chromosome and small rings of genes called plasmids.In genetic engineering pieces of chromosome from a different organism can be inserted into a plasmid.
For this experiment the researcher wanted to test different washing powders e.g. biological and non biological and also to leave clothes soak in blood for several minutes in bleach to discover if the blood could still be located, however (Eloisa et al 2009) discovered that using bleach on the materials they had used e.g. cotton and synthetic ...
(b) Some students wanted to find the optimum (best) temperature for using biological washing powder. A Petri dish was filled with agar jelly containing starch. A circular hole was cut into the centre of the agar. A solution of the biological washing powder was put …
Investigate effectiveness of a biological washing powder Plan: We will try and investigate how long it takes for the food stain to dissolve depending on the temperature, since the rate of reaction changes as the temperature changes. We will do this by using water with different temperatures.
Jan 16, 2013·Biological. Biological means the washing powder formula uses enzymes as a way of achieving a really deep down clean. This almost certainly means that you can wash at lower temperatures and with less water to achieve a really deep down clean. Different enzymes are suitable for different applications and fabrics.
1 A suitable dilution of detergent is around 5%, that is 5 cm 3 of detergent per 100 cm 3.This is calculated from the typical detergent pack suggestion of 100 cm 3 of detergent in a medium soil wash and machines using around 20 litres of water for the wash cycle.. 2 Provide portions of enzymes to add to known volumes of the detergent, or make up solutions of enzymes (protease only, lipase only ...
“Washing powders cleared of causing rashes,” reads the headline in The Daily Telegraph today. The newspaper describes a study that claims the idea that “biological washing powders can trigger skin irritations is a myth with no scientific basis”.
Biological washing powders contain enzymes. A student carried out an investigation using both biological and non-biological washing powders. Four white T-shirts were stained with egg yolk which is mainly fat. Each of the T-shirts were treated as follows: A C B D Wash with biological washing powder at 35°C Wash with non-biological washing ...
Problem-Which brand of washing powder will clean the bestAim-To find out which brand of washing powder will clean the best.Hypothesis-I think OMO will clean the best as it contains anionic and nonionic surfactants which are specifically used to lift dirt stains off.Variables- Constant: Stain producer, size of cloth, cloth material, water amount, dishwashing powder amount

Proteases in ‘biological’ washing powders At the start of the 20th century, German chemist Otto Röhm was trying to solve an unpleasant problem. He was trying to develop an improved method of ‘bating’, the process by which animal hides are softened before tanning to make leather. The motivation behind this
Oct 25, 2010·I don't use biological washing powder because in my family three of us have sensitive skin and the enzymes in biological powder can be irritating to sensitive skin (such as eczema). Some parents of babies and small children avoid biological powders for the same reason.
Biological washing powders contain enzymes which hydrolyse substances that cause stains on clothes. A manufacturer tested the ability of two types of the same brand of washing powder to remove different food substances that stain clothes. •€€€€€€€€Type A contained an enzyme.
Jun 13, 2008·an enzyme was used in a biological washing powder is a carbohydrate-digesting enzyme. describe how you would carry out an experiment to determine optimum temperature for this enzyme using the following apparatus and materials. -a solution of the biological washing powder -starch solution -water baths of various temperatures -food test reagents -standard laboratory apparatus
a) Biological washing powders contain protein-, fat- and carbohydrate-digesting enzymes to help remove stains. Name one other use for enzymes in the home or industry. b) Give one advantage of using enzymes in industrial manufacturing processes.

12 Biological washing powder contains enzymes to remove stains from clothes. Describe an investigation to find the temperature at which biological washing . powder is most effective at removing stains.Your answer should include experimental details and be written in full sentences.
Biological powder works best in warm water (that is 40 degrees) because the enzymes which digest the stains are destroyed by much higher heat. If you have dirty clothes (ie. vomity or pooey things or things stained with a lot of spilled food) that you want to wash in non bio, the best thing to do is to soak them in a bucket of hand-hot water ...
