The presence was indicated by the development of a red color several Klebsiella pneumoniae subspecies pneumoniae, Klebsiella pneumoniae subspecies rhinoscleromatis, Serratia proteamaculans subspecies proteamaculans, Phenol red glucose (dextrose) broth with Durham tube. Citrate is used by S. marcescens to produce pyruvic acid, thus it can rely on citrate as a carbon source and test positive for citrate utilization. In identifying the organism, one may also perform a methyl red test, which determines if a microorganism performs mixed-acid fermentation. S. marcescens results in a negative test. marcescens cannot split Tryptophan into the indole compound. The total soluble solids (SST) of each fruit (Lemon, Mango, and apple) juice were recorded using a refractometer, and the reducing sugar content of each fruit juices sample was measured by the DNS method [63].

WebWhen P. vulgaris is tested using the API 20E identification system [1] it produces positive results for sulfur reduction, urease production, tryptophan deaminase production, indole production, sometimes positive gelatinase activity, and saccharose fermentation, and negative results for the remainder of the tests on the testing strip. }Q;4$G9luo='w|g jNs(&4B|ytMc7-.HUp0=(/p2uKh;Z@QZ|s/ t$( }z1LqRdu:qNk=R/(`J@YzC+ Hc}#WptQ8 ZeHw%3.gK,i/I9_`^?:w]^.

About 20 enzyme-producing bacterial strains were isolated from municipal solid waste using the 16S rRNA method. It was used to isolate bacteria from avocado peel waste using serial dilution, pour plating, and streak isolation methods. McDevitt S. 2009. Similarly, the volume of juice variation from fruit to fruit that was treated with pectinase was investigated by using different fruits such as strawberry juice (7.0 10.0ml), grape juice (15.0 -21.5ml), apple juice (12.018.5ml), peach apple juice (12.010.5ml), chary apple juice (8.0 10.0ml) and orange juice (9.0 10.0ml) [29, 48].

Researchers studied avocado wastes that were found to contain four distinct bacterial strains. These results indicate that S. marcescens have latent ability to infect and circulate between both plants and animals. IOSR J Environ Sci Toxicol Food Technol. Acta Ophthalmol. 2001;17(1):7982.

This research work was supported by the Directorate of Research and Technology Transfer, Addis Ababa Science and Technology University, Addis Ababa, Ethiopia. Serological typing has also been used and this method seems to be a suitable first-line typing method for S. marcescens, although some strains remain untypable. The juice was centrifuged for 20min at 3000rpm, the supernatant was filtered out with filter paper, and the clarity of the juice was calculated by measuring the absorbance at 660nm with a UV spectrophotometer. In determining the antioxidant activity of each fruit juice sample, ABTS radical scavenging activities (ABTS-RSA) and DPPH radical scavenging activities (DPPH-RSA) of each fruit juice were evaluated, and the results were compared with the raw sample. are as follows: -. An Acad Bras Cinc. Pectinases and their uses are being studied in global research sectors to get optimal fastened activity with enzymes. Only 25% of the Microbial pectinase enzyme was used in the food and industrial sectors around the world, even though the market kept growing [16, 17]. J Am Acad Dermatol. The ABTS and DPPH radical scavenging activities of each fruit juice sample were determined using a modified version of the method published by Hosseini et al., [53]. Sucrose (saccharose) is a sugar that some bacteria can use because of an enzyme that begins the breakdown of this compound.
