Answer 1

Answers

The above all the answers that you have written is right, I am answering the item that is kept blank.

1. Deep wound - Alcohol and Oxidizing agents

Alcohol is a widely used antimicrobial agent as it denatures proteins. The alcohol solution that is ranging from 60-80% is highly used as an antimicrobial agent. Higher concentrations of alcohol or the 100% alcohols are less potent as the proteins don't denature efficiently in the absence of water. 70% ethanol or isopropanol are widely used as an antimicrobial agent for deep wounds. Oxidizing agents like Hydrogen peroxide is also used as antiseptic for deep wounds but it has also an adverse effect on the skin.

2. Lab benches - alcohol or phenolics

Phenol is one of the oldest antibacterial agents used in labs.  It acts as a bacteriostat and inhibits the biological process of bacteria. It is used at concentrations of 0.1%-1% for bacterial inhibition and  1%–2% for fungal inhibition.

Alcohol is a widely used antimicrobial agent as it denatures proteins hence 60-80% is highly used as an antimicrobial agent. 70% ethanol or isopropanol are widely used as an antimicrobial agent for cleaning lab benches.

3. Microbes for shipping- Surfactants or phenolics

Surfactants are widely used to clean the ship and various compartment of ships. The surfactants act on the bacterial membrane and disrupt it leading to damage to the bacterial membrane. Due to membrane damage cellular component come out of bacteria and hence microbes are killed.

Phenol acts as a bacteriostat and inhibits the biological process of bacteria. It is used at concentrations of 0.1%-1% for bacterial inhibition and  1%–2% for fungal inhibition. It is used to clean floors of ships.

4. Paper - Hot air and ionizing radiation

Any liquid medium can damage the structure of the paper and also can leave some traces of chemicals hence Hot air and ionizing radiation are used in the paper industry.

Hot air at a temperature of above 100 degrees can disrupt the bacterial surface and evaporate the liquid inside the cell. Due to the loss of liquid bacterial cell die.

Ionizing radiation like UV is used to inhibit bacterial growth. UV radiation acts on DNA and forms thymine dimer and damage the DNA. As the DNA is damaged the bacteria is killed

Hope this is helpful. Thank you
