Abstract
Considered bacteria Alastervtomiss of the most important types of bacteria Gram positive that live in the soil, where it produces many antibiotics and other sections of the outputs of bioactive secondary representation in human and veterinary Alsthaddam In the plant.
Alaktinomystadt produces about two-thirds of the antibiotics produced by micro-organisms and note that gender Alastervtomiss colonize the soil, especially in the area Rhizosphere and can produce many biologically active substances, this encourages on to say that he plays an important role in bio-control BIOLOGICAL CONTROL, especially with plant pathogens.
He called it the planning of this study in order to reach the strains with high efficiency in the production of antibiotics and the introduction recipes recipes and new genetic through mergers cellular and possibly get new antibiotics in addition to an assessment and genotype at the micro level of some of these genotypes New Subjects were Pfsm Genetics, Faculty of Agriculture, University of Kafr el-Sheikh, Egypt.
The results obtained can be summarized as follows: -
1 - when the comparative study between dynasties Alastervtomiss used in the study on the environment RYE FLAKES at intervals incubated different so as to know the best period incubated to produce antibiotics found that the best period incubated for higher productivity was after incubation for five days from the start of fermentation on the degree of 28 m and 120 rpm .
2 - chemical led treatment of MNNG different concentrations (3,2,1 mg / mL with bacteria S.fradiae and 6,5,4 mg / ml S.endus) for exposing one hour to the following results:
1 - Ntaqs percentage of vitality with increased exposure to higher concentrations.
