However, studies related to the use of enzymes for stone conservation are limited. Within this preliminary study, we applied commercially available enzyme-based treatments on biofouled natural building stones in the laboratory and in situ. Photography and spectrophotometry were used to monitor the effect of the treatment.

Investigating enzymes used in laundry detergents
Enzyme-controlled reactions often give higher product quality, lower manufacturing cost, less waste and reduced energy consumption. The technical effects of enzymes can be controlled by changing enzyme dose, temperature, and reaction time. Because enzymes are catalysts, the amount added to accomplish a reaction is relatively small.

Detergents: How do soaps and detergents bust the dirt from ...
Oct 02, 2018·In washing detergents, you'll find optical brighteners (which make your clothes gleam in sunlight). Biological detergents contain active chemicals called enzymes, which help to break up and remove food and other deposits. The main enzymes are proteases (which break up proteins), lipases (which break up fats), and amylases (which attack starch).
Microbial Proteases and Application as Laundry Detergent ...
The suitability of an enzyme preparation for use in detergents depends on its compatibility with the detergents at a high temperature. An ideal detergent enzyme should be stable and active in the detergent solution and should have adequate temperature stability to be effective in a wide range of washing temperatures (Bhosale et al ., 1995).

In this laboratory, we will study the effect of temperature, concentration and pH and on the activity of the enzyme catalase. Catalase speeds up the following reaction: 2 H 2 O 2-> 2 H 2 O + O 2. Hydrogen peroxide is toxic. Cells …
Effects of Detergents on Activity, Thermostability and ...
Mar 05, 2010·Effect of Detergents on Catalytic Activity . Detergents in general have close resemblance to lipase substrates, i.e., when exceeding their solubility concentrations they form micelles. Different detergents will influence lipase activity differently. Substrate and detergent interactions with lipases can be complex and unpredictable [25, 29-31].

In this laboratory, we will study the effect of temperature, concentration and pH and on the activity of the enzyme catalase. Catalase speeds up the following reaction: 2 H 2 O 2-> 2 H 2 O + O 2. Hydrogen peroxide is toxic. Cells therefore use catalase to protect themselves. In these experiments, we will use catalase enzyme from potato.

the extraction procedure—salt, detergent, and alcohol. Both the cell and nuclear membranes are composed primarily of lipids. In order for the cell to be lysed, the lipid walls must be broken down. The manual grinding and detergent solutions accomplish this. Soap molecules mix with fats or lipids, causing structures made of lipids to break apart.
