Release of intracellular components in downstream processing

Posted by admin on October 2, 2016 in Uncategorized |

Targets like recombinant proteins and many enzymes are intracellular in downstream processes.

Sometimes breaching of cytoplasm membrane and the cell wall can bring problems. This can occur

when the cell has a strong cell wall. The liberation of the DNA which can, in the long run increase

viscosity of suspension is some of the many problems that are associated with cell disruption. This

can affect further downstream processing. The DNAse addition can help to prevent this problem.

Heat is greatly released if the disruption that is involved is mechanical and this may need cooling

measures to be implemented. Products that are released by eukaryotes are subject to degradation by

the hydrolytic enzymes and this damage can be reduced by adding of enzyme inhibitors, rapid

processing and cooling of the cell extract.

Both mechanical and non mechanical means can be used to achieve cell disruption. The disruption

processes can be measured in terms of quantity by monitoring changes in absorbance, total protein

concentration, particle size or the activity of specific enzymes.

The following are methods for cell disruption in downstream processing

 Mechanical cell disruption

 Non mechanical cell disruption

There are several mechanical methods involved in cell disruption in downstream processing. There

are those methods based on solid shear and those that are based on liquid shear. The extrusion of

frozen cell preparations via a narrow orifice in high pressure is involved in solid shear. This method is

suitable in laboratory operations but not at factory level. Liquid shear methods are more effective.

Non mechanical cell disruptions are downstream processing methods that are alternative to

mechanical methods. This involves causing cells to be permeable. It can be achieved in several ways

including osmotic shock, autolysis, rupture with crystals or heat shock. More techniques have been

developed for small scale operations.

The advantages of outsourcing highly potent API production

Posted by admin on September 22, 2016 in Uncategorized |

The main advantage of outsourcing highly potent API (HPAPIs) manufacturers has abolished the need to

fund expensive containment base which can also be multifaceted to engineer install and maintain.

However, unless the particular the pharmacy company has a broad portfolio of HPAPIs in its pipeline for

instance infrastructure may not be fully utilized. Some of the highly potent API manufacturing benefits


API synthesis

Safe synthesis of HPAPIs requires considerable expertise in chemistry and a careful, rigorous approach to

Environmental Health and Safety (EHS). In API manufacturing, few CMO organizations offer the

services due to its high infrastructure costs the assets dedication to its high potency compounds.

Nevertheless, the GMP is required in the high amount to cross contamination within multi-product assets.

Currently, many biotech’s and emerging pharma companies and also CMOs rely broadly on the external

consultants to deliver pharmacological and toxicological guidance which eventually holds a grand final

categorization of an API. Having an in-house categorization expertise for APIs and upstream is very

critical, it ensures the expensive containment infrastructure is utilized where necessary and eventually

optimizes the economics of HPAPI manufacture in turn.

Cross contamination in API manufacturing

In API manufacturing, HPAPIs compliances with particular GMP aspects, this is also vital it helps to

prevent cross contamination between products which could bring severe harm to a patient. the GMP

necessitates the assessment of biological activities of the products produced to guarantee that proper

carry-over limits are set and followed accordingly while cleaning between the products. This has led the

development of cleaning protocols, analytical controls as well as maintenance of safe working practices

be the main elements of the HPAPI business. However, the entire APi manufacturing practices also

require particular expertise. The maximum allowed carryover limits are always severe since it requires the

development a very sensitive analytical methods to make sure all the limits are met.

Why you should take high potency mineral formula

Posted by admin on September 5, 2016 in Uncategorized |

Scientists normally say that you can meet all your nutritional needs through diet alone theoretically

but practically, most people do not. This is the main reason high potency supplementation comes in.

Probabilities of having a specific diet to meet the recommended dietary allowance for all required

nutrients are extremely unlikely with most people. So while it is theoretically that you can get all

nutrition you need from food. The fact is, most people do not. This is why you need to look for high

potency nutrition to supplement your diet and ensure that you get all the nutrition you need.

Minerals and vitamins serve as essential components in enzymes and coenzymes in the human body.

In order for chemical response needed for a person’s physical function to take place, enzyme

molecules need to get involved. Coenzymes help the enzymes in their reactions. They work together

to either join molecules together or split the molecules apart. Major idea in dietary drug is to provide

required aid or nutrients to permit enzymes work to optimum levels.

Most enzymes should be composed of essential minerals and protein in order to function properly. For

example, the enzymes which make active vitamin A in the ocular procedure is zinc, without zinc, and

then vitamin A is not activated to its lively state. The deficiency of either vitamin A or Zinc can result

into night blindness.

This is the reason why you need to take high potency mineral supplements in order to make sure that

your body is supplied with the needed minerals. Below are some of the importances of minerals in our


 Calcium- it is good for healthy teeth and bones

 Iron- building muscles naturally

 Zinc- helps in growth, immunity and fertility

 Magnesium- needed for making protein, nerve transmission and immune system health

Downstream Processing – Stage I

Posted by admin on August 29, 2016 in Uncategorized |

Solid-Liquid Separation

The first step or stage of the downstream processing is called Solid-Liquid Separation. Solid-Liquid

Separation includes the breaking of the cells and elements that are insoluble from the fermentation broth.

If the task is to produce an intracellular metabolite, then the intracellular metabolite has to be released

from the cells before the Solid-Liquid Separation process.

Some biologist instead of using the term Solid-Liquid Separation that refers to the separation of insoluble

elements from the fermentation broth use the harvesting term of the microbial cells.

There are several methods that are used in Stage I of the downstream processing, and those methods are:

 Flotation

 Flocculation

 Filtration

 Centrifugation


When we introduce a particular gas into the liquid broth, the gas produces bubbles in the liquid broth.

Solid particles and the cells in the liquid broth get adsorbed on the gas bubbles. The gas bubbles that form

in the liquid broth rise to the foam layer, and when they do so, they can be then removed and collected.

The foam, from which the gas bubbles are collected, that forms in the liquid broth, is facilitated by the

presence of certain substances known as collector substances.

The usual collector substances that facilitate the foam formation are long chain fatty acids and amines.


During the flocculation phase of Solid-Liquid Separation, the cells form large accumulations to settle

down for the easy removal.

Flocculation phase strictly depends on the cell nature and the ionic constitution of the medium.


The third subphase of the downstream processing process of Solid-Liquid Separation is Filtration.

Filtration is used for separating the biomass and filtrate.


Centrifugation is the fourth and the last process of the first stage of downstream processing called Solid-

Liquid Separation. Centrifugation technique is used for the separation of solid particles from the liquid

Conventional Plant Extraction

Posted by admin on June 26, 2016 in Uncategorized |

Resveratrol is situated in the skins and seeds of grapes, and also in blueberry, mulberries, cranberries and nuts, and in the roots of white hellebore and Japanese knotweed. While early resveratrol products were created from grape skins, most products sold now are manufactured from the more affordable, and more concentrated, Japanese knotweed. This plant extraction can also be known in Japan as kojo kon, and in China as Hu Zhang. Some nutritional supplements contain added red wine extracts, both for their resveratrol content and for advertising functions. At the typical mining process, Japanese knotweed roots are cut before being heated up in big alloy chambers known as extractors.

The plants are first examined to prevent pollution with heavy metals or compounds. Ethanol or methanol is employed as a solvent to individual the resveratrol from the plant extraction tissue, leading to a crude liquid extract. The detached resveratrol extract is prepared more by being go beyond a line of silica under high pressure, or by various other systems. It is then vacuum dry to remove the solvent and make resveratrol powder, which in turn is along with fillers like rice flour or hydroxypropylcellulose to manufacture tablets and capsules. When grapes are utilized to make resveratrol, the generation process is comparable to that described above.

Alcohol is employed to dissolve the resveratrol found in the skins or seeds, and the resultant liquid is refined further and dry. Due to the low relative content of resveratrol in grapes, products made solely from grapes are extremely expensive to produce. Scientists at the University of Alicante in Spain have now developed a biological approach to creating top quality resveratrol from grapevine cells. This method is cheaper and much more reliable than conventional plant extraction from grapes.
