References. In mango juice, there was a 13.34% difference in yield from control to crude pectinase and a 23.33% difference in juice output between crude pectinase and purified pectinase.

Serratia: Background, Pathophysiology, Epidemiology - Medscape 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. 2016;11:4755. [QxMD MEDLINE Link]. specific trait in a bacteria. Kouchak, F., & Askarian, M. 2012. infection. Thereafter, the bacterial suspension was vortexed, followed by centrifugation at 10,000 g for 30 minutes to remove undissolved For information on how to determine the ability of a microbe to use sucrose, refer to the Sucrose fermentation test. EXTRACTION, CHARACTERIZATION AND OPTIMIZATION OF S. In the field of science, experimentation is the cornerstone of changing hypotheses into Biologists have used a series of biochemical tests to distinguish closely related bacteria in the detection of bacteria [27].

It reduced the presence of cohesive network structure in fruit juice samples. N Engl J Med. Arabinose Some of the characteristics are as follows: Fermentation of. 2022 Dec 5;11(12):1473. doi: 10.3390/pathogens11121473. The Voges Proskauer test About 20 enzyme-producing bacterial strains were isolated from municipal solid waste using the 16S rRNA method. 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. LWT. The following biochemical tests were performed to identify bacterial isolates: carbohydrate fermentation tests, indole test, methyl red (MR) test, Vegas-Proskauer (VP) test, Citrate utilization test, hydrogen sulfide generation test, catalase test, and urease test [59]. The colonies were pigmented only at room In this analysis, the optimum fermentation period for pectinase development was found to be 72h, and the highest pectinase activities were found to be 6.860.32mol/ml/min of released glucose [Table 4] when pectin was used as a substrate. 1. 2018;1:16. 2007 Sep 1. The sequences of the W3 search (mBLAST, NCBI) showed 86% similarity to the nucleotide of Lysinibacillus sp., and 85% similarity to the nucleotide of Lysinibacillus macrolides in the phylogenetic tree (Fig. Finally, the PCR products were sequenced, and the obtained sequence data were analyzed using the basic local alignment search tool (BLAST) software (http://www.ncbi.nlm.nih.gov/blast) against the 16S ribosomal RNA sequence database, with the mega X software (http://www.ncbi.nlm.nih.gov/mahalik) to generate the phylogenetic tree from the national center for biotechnology [44].
