[Function]

Grapes (Vitis vinifera) have been heralded for their medicinal and nutritional value for thousands of years. Egyptians ate grapes a very long time back, and several ancient Greek philosophers spoke about the healing power of grapes — usually in the form of wine. European folk healers made an ointment from the sap of grapevines to treat skin and eye diseases. Grape leaves were used to stop bleeding, inflammation, and pain, such as the kind brought on by hemorrhoids. Unripe grapes were used to treat sore throats, and dried grapes (raisins) were used for constipation and thirst. Round, ripe, sweet grapes were used to treat a range of health problems including cancer, cholera, smallpox, nausea, eye infections, and skin, kidney, and liver diseases.

Grape seed extracts are industrial derivatives from whole grape seeds that have a great concentration of vitamin E, flavonoids, linoleic acid and phenolic OPCs. The typical commercial opportunity of extracting grape seed constituents has been for chemicals known as polyphenols having antioxidant activity in vitro.

Griffith’s experiment, reported in 1928 by Frederick Griffith,[1] was one of the first experiments suggesting that bacteria are capable of transferring genetic information through a process known as transformation.[2][3]

Griffith used two strains of pneumococcus (Streptococcus pneumoniae) bacteria which infect mice — a type III-S (smooth) and type II-R (rough) strain. The III-S strain covers itself with a polysaccharide capsule that protects it from the host’s immune system, resulting in the death of the host, while the II-R strain doesn’t have that protective capsule and is defeated by the host’s immune system. A German bacteriologist, Fred Neufeld, had discovered the three pneumococcal types (Types I, II, and III) and discovered the Quellung reaction to identify them in vitro.[4] Until Griffith’s experiment, bacteriologists believed that the types were fixed and unchangeable, from one generation to another.

In this experiment, bacteria from the III-S strain were killed by heat, and their remains were added to II-R strain bacteria. While neither alone harmed the mice, the combination was able to kill its host. Griffith was also able to isolate both live II-R and live III-S strains of pneumococcus from the blood of these dead mice. Griffith concluded that the type II-R had been “transformed” into the lethal III-S strain by a “transforming principle” that was somehow part of the dead III-S strain bacteria.

Today, we know that the “transforming principle” Griffith observed was the DNA of the III-S strain bacteria. While the bacteria had been killed, the DNA had survived the heating process and was taken up by the II-R strain bacteria. The III-S strain DNA contains the genes that form the protective polysaccharide capsule. Equipped with this gene, the former II-R strain bacteria were now protected from the host’s immune system and could kill the host. The exact nature of the transforming principle (DNA) was verified in the experiments done by Avery, McLeod and McCarty and by Hershey and Chase.

Product Review: Bee Pro Pollen Substitute – Feeding – #Beekeeping Basics – The Norfolk Honey Co.

In the previous video I showed how I mix up my pollen substitute and in this video I am showing you how I feed it to the bees. I picked a sunny day and the bees were very active!

I have used a few different types of Pollen Substitute but never Bee Pro from Mann Lake which is stocked in the UK by Bee -Equipment.co.uk
This video is not sponsored and the product has not been supplied free of charge. I purchased it from their website paying the full amount including postage.
In this video you will hear my honest thoughts of this product in terms of the purchase, delivery and mixing of the product. I will follow this video with another showing how I use it on my colonies and how the bees react to it.

Here is the description from the Mann Lake product page:
Amino acids are the building blocks of protein. Different protein sources contain different amino acid levels; it’s for this reason that a mixture of protein sources should be included in a pollen substitute. A correct amino acid balance is the key to efficient utilization of protein.

Protein quality is determined by its level of essential amino acids. A shortage of any one essential amino acid makes overall protein utilization by the bee less efficient. For example, the bees require 4% Iso-leucine. If the current feed you are using only has 3% Iso-leucine, your bees can only utilize 75% of the available protein.

Can be fed in dry form in a feeder box placed in the yard or made into patties by mixing with high fructose corn syrup or sugar syrup and placed in the hive.
Free of all contaminants. Natural pollens may contain pesticide residue and disease carrying bacteria (foulbrood).
Can be used for building colonies in late winter or early spring, to prepare for pollination and to maintain or increase brood production prior to and after honey flow.
Gives your bees the best nutrients available for the production of larval food.
High protein pollen substitute which supplies the lipids, minerals, and B-complex vitamins honey bees need to produce larval food.
Specially formulated for the commercial beekeeper who is feeding syrup as the source of carbohydrates in the bee’s diet.

I purchased this product in the UK from the following website, I do not currently (Jan 2017) receive any commission for promoting this company or product:
