Abstract |
: |
In this research study are Alaktinomystadt and the spread in the twenty-three soil samples taken from the western region in the Kingdom, have varied the number of these different reporting a large group of the sample to another, where the highest density in the three samples were collected from the soil of Medina. The definition of farmer Alastervyumiss, and found that they follow the race Alastervyumiss, as noted the presence of six chains of color in the soil samples are gray, white, red, yellow, blue, green, and was particularly prevalent in soil samples is the string of gray, and Oqlhma prevalent is the string blue, then the series green, and disagreed vulnerable to counter these isolates, it was noted that isolates of the series Elzimadah red and more active in the inhibition of the microbes tested (bacteria - Khmer - mushroom) for isolates of the chains color yellow and white, while not shown isolates of the chains blue, green, any activity that might protect against these microbes tested.
1 - pointed the way to the filtrate Stervyumiss MR13 (red series) gives effect with a wide range, since the antibiotic was secreted effect against ten strains of the thirteen strains tested (79.92%).
2 - affected the amount of biomass, growth standards, and the activity of the antibiotic to the dynasties Stervyumiss MR13.MY18 strongly depending on temperature and ventilation.
3 - The starch and nitrate Kmusdra carbon and nitrogen, respectively, an important role in increasing the activity of antibiotics in farm leaky.
4 - The results of the continuous development of the strain MY18 Stervtomessis in the laboratory at different rates ease, that the highest efficiency in the use of food additives have been obtained at 0255 t / h, easing rate (5.25 ml / hour rate of addition).
5 - It was noted that the optimal degree of pH (pH) of the strain Stervaomitis MY18 is 7, and to increase it and increase or decrease this level has led to a decline in respiratory rate, and thus the impact on the amount of biomass and antibiotic, and gave the antibiotic crude extract Balbiotanol active abundant compared Balttraseklin. |
