Downstream processing refers to the recovery and purification of biosynthetic products, particularly pharmaceuticals, from natural sources such as animal or plant tissue or fermentation broth, including the recycling of salvageable components and the proper treatment and disposal of waste.
Steps involved in fermentation products producing a viable product output.various steps and process were explained in them. A semester syllabus of undergraduate microbiology student in his/her semester -5 in paper -6 . I think this might be helpful to you and have a good response after reading this .thank you.

The heart of the fermentation or bioprocess technology is the Fermentor or Bioreactor. A bioreactor is basically a device in which the organisms are cultivated to form the desired products. it is a containment system designed to give right environment for optimal growth and metabolic activity of the organism.
A fermentor usually refers to the containment system for the cultivation of prokaryotic cells, while a bioreactor grows the eukaryotic cells (mammalian, insect cells, etc).
Microbial Kinetics in Batch Culture
Culture system containing a limited amount of nutrient, which is inoculated with the microorganism. Cells grow until some component is exhausted or until the environment changes so as to inhibit growth. Biomass concentration defined in terms of cell dry weight measurements (g/l) or total cell number (cells/ml).

Product Yield Coefficient
Maintenance:
Cells use energy and raw materials for two functions, production of new cells and the maintenance of existing cells. In general, consumption of materials for maintenance is small w.r.t. the amount of materials used in the synthesis of new biomass.
Generally it is assumed that the use of materials for maintenance is proportional to the amount of cells present.

Bioprocess technology is a vital part of biotechnology that deals with processes combining all living matter or its components with nutrients to produce specialty chemicals, reagents, and biotherapeutics. These processes form the backbone of translating discoveries of life sciences into useful industrial products.
The various stages of processing that occur after the completion of the fermentation or bioconversion stage, including separation, purification, and packaging of the product

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
How to Split Bills in the Odoo 17 POS ModuleCeline George
Bills have a main role in point of sale procedure. It will help to track sales, handling payments and giving receipts to customers. Bill splitting also has an important role in POS. For example, If some friends come together for dinner and if they want to divide the bill then it is possible by POS bill splitting. This slide will show how to split bills in odoo 17 POS.
This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

2. Downstream processing, what and why
Downstream processing is any treatment
of culture broth after fermentation to
concentrate and purify products.
2
4. Cell disruption
• Some product are intracellular including many
enzymes and proteins required to disrupt the cell
and release these products e.g. Yeast
• Cell disruption can be achieved by both
mechanical and non-mechanical methods.
• Mechanical- sonication and liquid shear
homogenization etc
• Non mechanical- autolysis, osmosis shock etc.
6. Filtration
Separation of particles from liquid by applying
a pressure to the solution to force the solution through
a filter. Filters are materials with pores.
Particles larger than the pore size of the
filter are retained by the filter.
Particles smaller than the pore size of the filter pass
through the filter along with the liquid.

Membrane Fraction Technologies
Reverse Osmosis
(<200 MW)
Ultrafiltration
(2000 - 50,000 MW)
Nanofiltration
(200 - 700 MW)
Micro filtration
(100,000 MW)
8. Centrifugation
Centrifugation used to separate particles as
small as 0.1μm diameter and is also suitable
for some liquid-liquid separations.
Higher speed centrifuge are required for the
separation of the smaller particles
Use of the centrifugal force for the separation
of mixtures
11. Product purification
• Removing components with properties similar
to those of the products
Chromatography
• Separates molecules by their chemical and
physical differences
E.g. – adsorption chromatography
•
affinity chromatography
•
ion exchange chromatography etc.
13. dialysis
• These membrane separation techniques are
primarily used for the removal of low molecular
weight solutes and inorganic ions from a
solution
Distillation
• Separating components with different
volatilities. Such as organic solvents , beer, wine
and sprits.
14. Product Polishing
Final processing steps which end with
packaging of the product in a form that is
stable and easily transportable
Crystallization, concentration and drying
are typical unit operations
17. Drying
Drying involves the transfer of heat to the
wet material and removal of the moisture as
water vapor.
Drying Methods

Atmospheric drying
Vacuum drying (Decompression )
Freeze-drying (lyophilization)
Spray drying
18. lyophilization
Freezing the material
Reducing the surrounding pressure and
adding enough heat to allow the frozen
water in the material to sublime directly
from the solid phase to gas.
