2011 Feb. 117(2 Pt 2):485-6. making it difficult to detect. Phenol Red Arabinose Broth. Int J Mol Sci. Serratia marcescens: a key pathogen caused ginger rhizomes soft was a red top layer of liquid (McDevitt S. 2009). marcescens cannot split Tryptophan into the indole compound. Researchers are becoming more interested in nanoparticles as a result of their vast Fermentation tests. 2]. According to Kothari and Baig [41], the maximum polygalacturonase activities were produced at a temperature of 35C byErwiniacarotovora. Prithiv J Prasad, MBBS Resident Physician, Department of Internal Medicine, Albert Einstein Medical CenterDisclosure: Nothing to disclose. alkaline end product. These results indicate that S. marcescens have latent ability to infect and circulate between both plants and animals. There are other biochemical tests that help to identify Serratia marcescens in the lab. It is negative for the methyl red test due to their production of 2, 3 - butanediol and ethanol, but positive for the Voges-Proskauer test, which shows an organisms ability to convert pyruvate to acetoin . To address this demand for pectinase, a bacterial source of pectinase could be used. 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. PNAS Nexus. Ostrowsky BE, Whitener C, Bredenberg HK, et al. Pectinases are used in acidic and alkaline environments and are especially useful in the food and textile industries [25, 26]. The usually red colonies had a bluish tinge when seen against The organism is not capable of fermenting dulcitol which results in the formation of acidic end Pectinase-producing bacteria were isolated from coffee pulp [32], and the results of the secondary screening method were lower than isolate R5. Methods Isolation and cultivation of S. marcescens Serratia marcescens (YC16) was isolated from ginger rhizomes with evidence of visible rot symptoms. https://doi.org/10.1016/B978-0-12-815259-1.00008-2. If an organism can reduce sulfur, the hydrogen sulfide gas which is produced will react with the iron to form iron sulfide, which appears as a black precipitate. The viscosity, pH and acidity, total soluble solids (TSS), total titratable acidity (TTA), reducing sugar content, pectin presence test, Total phenolic content (TPC), and Antioxidant activity of three different fruits [apple, lemon, and mango juice] were evaluated, and the results were compared to the raw sample (untreated juice is a control), as shown in Tables 10 and 11. and was not specific for the growth of Serratia Obafemi YD, Ajayi AA, Taiwo OS, Olorunsola SJ, Isibor PO.
