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. In a positive test, the pH indicator in the medium changes color from its normal red to yellow, indicating acid production.

Food Chemistry. the intermediates of the fermentation pathway. The products a bacteria produces by the anaerobic fermentation of glucose help In the same bacterial species (Erwinia spp), the highest pectinase (polygalacturonase and pectin lysate) activity was recorded at a temperature of 35C [5, 42]. Some strains of S marcescens are capable of producing a pigment called prodigiosin, which ranges in color from dark red to pale pink, depending on the age of the colonies.

The production of different enzymes by S. marcescens as virulence factors has also been reported, including chitinase, lipase, chloroperoxidase and an extracellular protein, HasA. To address this demand for pectinase, a bacterial source of pectinase could be used. Lemon, mango, and apple fruits were washed carefully and chopped into smaller sizes on the side with a sharp knife. It is used to differentiate enterics based on the ability to reduce sulfur and ferment carbohydrates. 2012;26(2):10723. 2016;4(1):85362.

The API 20E system has been used widely, but is not individually satisfactory. This study tried to determine the effect of pectinase on the volume of juice, juice yield, and juice clarity in terms of transmittance by using apple, lemon, and mango fruits. The result of mango juice transmittance obtained in this current experiment affirms the report made by Kumar et al., [50], who received 92.5% of transmittance after 150min of incubation time. Pectinase activity was determined by measuring the amount of released reducing sugar under assay conditions or by enzymatic degradation of pectin as described Nelson-Somogyi methods. glucose.

The authors declare that they have no competing interests. Once the medium has been acidified, the enzyme arginine dihydrolase is activated. Thereafter, the bacterial suspension was vortexed, followed by centrifugation at 10,000 g for 30 minutes to remove undissolved culture of the test culture. In this exercise, there were about 16 different possible bacteria that could have been endobj The usually red colonies had a bluish tinge when seen against It also changes to magenta or hot pink at pH >8.4.

[QxMD MEDLINE Link]. 12 0 obj The fruits contain a high amount of pectin; the extraction of fruit juice has historically resulted in a cloudy, unappealing color and high viscosity. This showed that bacterial strains could make pectinase, which was found by Huguevieux et al., [35]. Serratia infection has caused endocarditis and osteomyelitis in people addicted to heroin. Urea methyl red test evaluates if a bacterium went through mixed acids fermentation after being given where RG is released glucose obtained from D-glucose standard curve. The sterile inoculating loop was used to pick up an inoculum Chapman J, Ismail AE, Dinu CZ. 2018;33(1):115. Then, the mixed solution was incubated at 40C in the water bath for 40min. The pectinase activity increased when we reached the optimum pH and decreased after the optimum pH value. Punjab Univ J Zool. DTC agar was the enrichment Dr. Coombs, Serratia marcescens is a common nosocomial pathogen that was the unknown bacteria in To study the influences of substrate concentration on enzyme production using the bacterial isolate, the enzyme was produced by various concentrations of substrates (pectin).
