bioreactors and fermentors are culture systems to produce cells or organisms. They are used in various applications, including basic research and development, and the manufacturing of biopharmaceuticals, food and food additives, chemicals, and other products. A broad range of cell types and organisms can be cultivated in bioreactors and fermentors, including cells (like mammalian cell lines, insect cells, and stem cells), microorganisms (like bacteria, yeasts, and fungi), as well as plant cells and algae.Bioreactor and fermentor are two words for basically the same thing. Scientists who cultivate bacteria, yeast, or fungi often use the term fermentor. The term bioreactor often relates to the cultivation of mammalian cells but is also generically used.

Bioreactors - Basic Designing and Types.pptxKaviKumar46
A bioreactor is a device that supports a biologically active environment. It is used for growing cells or fermenting chemicals produced by cells. Bioreactors come in various designs depending on their application and scale of production. They provide control over environmental factors like temperature, pH, and aeration to optimize cell growth and product formation. Common bioreactor types include stirred tank, bubble column, packed bed, fluidized bed, and membrane bioreactors. Each bioreactor design aims to efficiently culture cells while controlling critical process parameters.
A fermentor, also known as a bioreactor, is a closed vessel used for commercial fermentation processes. It provides controls for factors like temperature, pH, aeration and agitation to maintain optimal conditions for microbial growth. Early large-scale fermentors had capacities over 20 liters and were used to produce products like yeast and acetone.

A Review on Recent Advances of Packaging in Food IndustryPriyankaKilaniya
Effective food packaging provides number of purposes. It functions as a container to hold and transport the food product, as well as a barrier to protect the food from outside contamination such as water, light, odours, bacteria, dust, and mechanical damage by maintaining the food quality. The package may also include barriers to keep the product's moisture content or gas composition consistent. Furthermore, convenience is vital role in packaging, and the desire for quick opening, dispensing, and resealing packages that maintain product quality until fully consumed is increasing. To facilitate trading, encourage sales, and inform on content and nutritional attributes, the packaging must be communicative. For storage of food there is huge scope for modified atmosphere packaging, intelligent packaging, active packaging, and controlled atmosphere packaging. Active packaging has a variety of uses, including carbon dioxide absorbers and emitters, oxygen scavengers, antimicrobials, and moisture control agents. Smart packaging is another term for intelligent packaging. Edible packaging, self-cooling and self-heating packaging, micro packaging, and water-soluble packaging are some of the advancements in package material.

determine the relative importance of causes of illness, disability, and death;
identify those segments of the population that have the greatest risk from specific causes of ill health; and
evaluate the effectiveness of health programs and services in improving population health.
