Her research interests include Bio-fertilizers, Plant-Microbe Interactions, Molecular Microbiology, Soil Fungi, and Fungal Ecology. Nutrient agar is a general-purpose medium used to grow bacterial species. Definition ; it is an synthesis method to grow the bacteria from infect material like blood sputum. Liquid culture media are solidified with agar, typically at 1–2%. Liquid media are generally poured into test tubes or culture bottles. The text deals with the industrial processing of milk, the problems solved in the industry, and those still affecting the processes. Selective Media. Bacteriology is the branch of biology that studies the morphology, ecology, genetics and biochemistry of bacteria. Since 1935, BD BBL ™ prepared media have brought high quality and high performance to the microbiology laboratory.
