What time the culture does reach Stationary Phase?1. What is the active substance and activity/indication (e.g. antibacterial, anti-inflammatory) of sibuyas or Allium cepa?Enterobacteriaceae species might be differentiated (from one another) by all of the following except: o amino acid fermerntation o lactose fermentation O oxidase test o Eosin Methylene Blue agar o MacConkey agar
- My professor instructed me to make presentation on this topic "Application of FISH for diagnosis of oral microbial diseases". He instructed me to make 4 slides, can you give me proper information and some points which i can include on those 4 slides? It will be great if you do so... Please answer at your own easy words .Temperature plays a very important role in the growth of fungi, bacteria, and other microorganisms. Most bacteria grow at optimal temperatures. Mesophiles are grown mainly at optimum temperature. What is is the impact of the above on a) on unpasterized milk? 2. Expired date and off-putting odor?Microbial secondary metabolites are compounds produced by strains of certain microbial(antimicrobial agent).such as penicillin and cephalosporin. Describe the industrial fermentation process of each of these antibiotics. 1.media preparation (carbon source, nitrogen source, salts, oxygen requirements),Temperature and pH maintained.
