Oil emulsion dressings are used for wound care, providing a moist environment to aid in healing and protect the wound from further injury. To use it, first clean the wound with a saline solution or as directed by a healthcare provider. Dry the surrounding skin gently. Open the dressing’s sterile package; avoid touching the part that will be in contact with the wound. Place the dressing directly onto the wound. If the wound is large, multiple dressings can be overlapped. Secure the dressing with a secondary bandage, like gauze or a wrap, to hold it in place. Change the dressing according to the instructions provided by the healthcare provider, usually when it becomes saturated or as directed. Dispose of the used dressing properly. Always follow the specific recommendations of healthcare professionals regarding wound care and dressing changes.

Cellulose, a polysaccharide and a major component of plant cell walls, is notoriously tough and resistant to breakdown. Its breakdown primarily occurs through enzymatic actions, specifically by enzymes known as cellulases. These enzymes are secreted by certain bacteria, fungi, and protozoans, which can be found in the digestive systems of some animals, including ruminants like cows and termites, facilitating their ability to digest cellulose-rich plant material. In industrial applications, cellulases are harnessed to convert cellulose into glucose, which can then be fermented into biofuels or transformed into other valuable biochemicals. Additionally, in the human-made processes such as paper and textile manufacturing, cellulases are used to modify the properties of cellulose-containing materials. Though humans and many animals cannot produce cellulases, they rely on symbiotic gut microbes to partially break down cellulose into digestible carbohydrates.
