Serratia rubidaea(E9.HM585373) was isolated from tomato fruits and characterized using the 16S rRNA method. The selected isolates from the primary screening method were subjected to fermentation in a suitable medium, and their behaviors were assessed to be further screened. With the company's permission, a sample was taken from ECOPIA PLC in Addis Ababa, Ethiopia. An outbreak of S marcescens bloodstream infections was identified in patients receiving contaminated bags of parenteral nutrition. [QxMD MEDLINE Link]. The test detects the presence of aceylmethylcarbinol, This can be tested by transferring a pure sample of bacteria from the culture to a sterile tube containing a mixture of urea agar broth and phenol red. A Single colony of R5 isolate was inoculated in 15ml of yeast extract pectin broth and incubated at a temperature of 30C overnight. 1939. Around 8ml of each fruit juice was taken and chilled in a water bath before adding the pectinase enzyme product, after heating at 40C to inactivate any natural fruit enzymes or bacteria present. Explains that serratia marcescens su-10 is optimized for prodigiosin production and its bioactivity. If the butt of the slant is obscured by the precipitate, look at the top of the slant to determine if the organism could ferment only dextrose (red), or if it could ferment either lactose and/or sucrose (yellow). This result was similar to that of [37, 52], which was done on the clarification of apple juice by pectinase. the bacterial decarboxylation of lysine which [15] Outbreaks of S marcescensmeningitis, wound infections, and arthritis have occurred in pediatric wards.

In the field of science, experimentation is the cornerstone of changing hypotheses into The pectinase isolated from the bacteriumSerratia marcescenscould clear fruit juices. Mannitol is fermented by Staphylococcus aureus and will cause a pH change in the medium (acidic) that is detected by observing phenol red changing to yellow. The uses of these enzymes are depicted in Fig. Single colonies grown on pectin agar media were smeared and examined under the microscope for morphological conformity using gram staining.

On a 0.8% agarose gel dyed with a DNA-safe stain, the PCR products were seen. This would be read K/A,G. The result of the total phenol content of each fruit juice sample also showed a decreasing trend after the treatment of the juice with pectinase, as shown inTable 11. 2018;56(1):110.
