Michael Stuart Bronze, MD David Ross Boyd Professor and Chairman, Department of Medicine, Stewart G Wolf Endowed Chair in Internal Medicine, Department of Medicine, University of Oklahoma Health Science Center; Master of the American College of Physicians; Fellow, Infectious Diseases Society of America; Fellow of the Royal College of Physicians, London Three different fruits which have the signs of physical damage (lemon, mango, and apple fruits) were bought from a fruit market (Akaki Kality, Addis Ababa) and brought to microbiology laboratories for juice preparation [61]. The miracle microbe: Serratia marcescens. The purity of the test isolate was assessed using colony morphology and microscopy; pure colonies of bacteria were preserved with 20% of glycerol and stored at -80C for further study [56].

The Voges Proskauer test Other recent investigations indicated that the highest amount of pectinase produced byEntero bactertabaci NR1466677 was at the optimal temperature of 35C [9, 30]. Marcescens Voges <> Serratia marcescens is negative for acid production on lactose, but positive glucose and sucrose (with gas production) fermentation. Nitrate tests are positive since nitrate is generally used as the final electron acceptor rather than oxygen . Citrate (positive test) is used by Serratia marcescens to produce pyruvic acid. DTC agar was the enrichment Observe each tube for color change to yellow, indicating production of acid.Also, examine the Durham tube in each tube for the presence of large gas bubbles.2. The relative activity of each parameter was calculated as the percentage by using the following formula:-, where As = the activities of sample in mol/ml. Growth on Macconkey's agar.

The production of pectinase was optimized by using four parameters namely, fermentation time, temperature, pH, and substrate concentration. The medium is a nutrient broth to which 0.5-1.0% sucrose is added. The researchers isolated four different bacterial strains from avocado peel waste samples.

It also speeds up tea fermentation and eliminates the foam-forming property of instant tea powder by destroying the pectin present in tea powder. This happens with Salmonella and Shigella.
