Most of the antibiotics used today are from the microbes. The soil fungi were isolated by the soil dilution method. Selective media were used in theisolation of Aspergillus species from soil and maize kernel samples. Identification and characterization of the soil mycoflora were done with the help of authentic manuals of soil fungi. 3.Shake well for at least one minute. Fungi are very successful inhabitants of soil, due to their high plasticity and their capacity to adopt various forms in response to adverse or unfavorable conditions (Sun et al., 2005).Due to their ability to produce a wide variety of extracellular enzymes, they are able to break down all kinds of organic matter, decomposing soil components and thereby regulating the … Glucose serves as a readily metabolizable carbon source whereas dipotassium phosphate buffers the medium. Out of 20 soil samples 18 Bacillus spp. Introduction It is crucial in the field of microbiology to study the morphology‚ biological activity‚ and the behavior of microbes thus the isolation of such microbes from the environment is necessary because it allows scientists to study them in close proximity. These suspensions were stirred for 20 min before making 7-fold falling dilutions and distributing 0.1-ml (this is the 10-3 dilution). The Fungi grown on the selective media supported the growth of the fungi by using 1 Amjad Khan Afridi 29 /07/ 2016 Isolation of Antibiotic ( Secondary metabolites) producing fungi from soil Purpose: To isolate secondarymetabolites (antibiotic , enzymes, proteins etc..) producing Fungi from soil samples. 2.

The samples were collected in sterile polythene bags, closely tightened, and were taken to the laboratory. Soil Dilution Plate Method (Waksman,1922): soil dilutions were made by suspending 1g of soil of each sample in 10ml of sterile distilled water. Taxa abundance distribution Table 3. Hence in order to have a cross section of the soil micro-flora, it is necessary that several synthetic or semisynthetic media should be used. For the isolation of fungi, bacterial growth is suppressed by adding 1-2 mg/litre Strepto- penicillin after autoclaving or 12 mg Rose Bengal before autoclaving.
