16/09/ · Pure cultures can be successfully stored at °C either in refrigerators or in cold-rooms. This method is applied for short duration ( weeks for bacteria and months for fungi) because the metabolic activities of the microorganisms are greatly slowed down but not stopped. ADVERTISEMENTS: Thus their growth continues slowly, nutrients are utilized and waste products released in medium. 16/09/ · Enrichment Culture Method. 1. Streak Plate Method: This method is used most commonly to isolate pure cultures of bacteria. A small amount of mixed culture is placed on the tip of an inoculation loop/needle and is streaked across the surface of the agar medium (Fig. ). The successive streaks “thin out” the inoculum sufficiently and the. PURE CULTURE TECHNIQUES I. OBJECTIVES • To demonstrate good aseptic technique in culture transfer or inoculation and in handling sterile materials. • To demonstrate skill in isolation of organisms from a mixed culture using selective and differential media. • To isolate microorganisms from a wide variety of sources and describe their colonial morphology. II. INTRODUCTION Most.

Pure culture techniques were in turn applied to commercial fermentations, which provided more consistent yields of the products desired. Such cultures have been used to make alcohol, yogurt, and citric and lactic acid and other useful products. The techniques also made possible the development of vac- cines and antibiotics. Lab Exercise 5: Pure culture techniques OBJECTIVES 1. Perform a streak-plate to separate the cells of a mixed culture so that discrete colonies can be isolated. 2. Perform a pour-plate (loop) dilution to separate cells of a mixed culture and compare growth characteristics beneath and on the surface of the agar.

A pure culture may be isolated by the use of special media with specific chemical or physical agents that allow the enrichment or selection of one organism over another.
