Which process is also called product recovery?

Which process is also called product recovery?

Explanation: Downstream processing implies manufacture of a purified product fit for a specific use, generally in marketable quantities, it also refers to the recovery and purification of biosynthetic products, particularly pharmaceuticals, from natural sources such as animal or plant tissue or fermentation broth.

What is product recovery?

the series of activities, including collection, separation, processing, by which products or other materials are recovered from or otherwise diverted from the solid waste stream for use in the form of raw materials in the manufacture of new products other than fuel [12]. 4.1 Summary of Research Definitions.

Which material is disengaged in the disengagement zone?

Which material is disengaged in the disengagement zone? Explanation: The sudden widening at the top of the reactor slows the bubble velocity and thus disengages the bubbles from the liquid flow. Carbon-dioxide rich bubbles are thus prevented from entering the downcomer.

Which of the following is not a probiotic?

Which condition is correct according to the growth of cells in beginning?

Which condition is correct according to the growth of cells in beginning? Explanation: Growth always appears much slower at the beginning of culture because the number of cells present is small. 5. The specific growth rate of cells is independent on the concentration of nutrients in the medium.

What are the phases of growth?

There are three phases of growth – meristematic, elongation and maturation. We can understand this better by looking at a seed. We already know that the tips of roots and shoots exhibit continuous growth and hence are meristematic. The cells in this region are rich in protoplasm and have large nuclei.

What affects the growth of bacteria?

Warmth, moisture, pH levels and oxygen levels are the four big physical and chemical factors affecting microbial growth.

What are the 4 conditions which allow bacteria to grow?

Most bacteria grow best within certain ranges of temperature, and have specific requirements related to their need for air, the proper amount of water, acid and salt. By controlling nutrients, water, temperature and time, air, acidity, and salt, you can eliminate, control, or reduce the rate at which bacteria grow.

What are the 6 conditions that affect the growth of microorganisms?

FAT TOM is a mnemonic device used in the food service industry to describe the six favorable conditions required for the growth of foodborne pathogens. It is an acronym for food, acidity, time, temperature, oxygen and moisture.

What food is at a temperature that allows bacteria to grow?

Warmth – the ‘danger zone’ temperatures at which bacteria grow best are between 5ºC and 63ºC. Food – like any other living things, germs need food to grow. High-risk foods that bacteria love best include dairy products, meat, poultry, fish and shellfish.

What are high risk foods?

High risk foods share a tendency to spoil as a result of unsuitable storage conditions or improper cooking methods. Meats, fish, gravy, sauces, shellfish, dairy products, pasta and even cooked rice are all examples, and the smallest errors can lead to contamination.

Is flour a high risk food?

These foods include cereals, flour, sugar, unopened canned goods, dried products, sauces and spices. They do not support the growth of bacteria like the high risk/high moisture foods. They can lose quality from being kept too long in storage and their major source of contaminants is pests.

What is the safest way to eat eggs?

Overall, shorter and lower-heat cooking methods cause less cholesterol oxidation and help retain most of the egg’s nutrients. For this reason, poached and boiled (either hard or soft) eggs may be the healthiest to eat. These cooking methods also don’t add any unnecessary calories.
