Fungal organisms produce the vast majority of pectinase used in the industrial environment. results in the formation of alkaline end products. Childhood delayed septic arthritis of the knee caused by Serratia fonticola. Although the maximum pectinase activity was 7.7656mol/ml/min of glucose released at 35C, pectinase activities above the optimal temperature were frequently higher than those below the optimal temperature [Table 6]. This showed that bacterial strains could make pectinase, which was found by Huguevieux et al., [35]. They are gram -ve, catalase +ve, oxidase -ve, citrate +ve, MR -ve, VP +ve, urease -ve bacteria. The yield variation of apple juice between control and crude pectinase was 20%. Friedman ND, Peterson NB, Sumner WT, et al. 2001;17(1):7982.

Therefore, apple fruit showed consistent variation from control to crude and crude to purified pectinase. In adults, most Serratia infections are isolated, but occasional nosocomial outbreaks occur.

Khanna A, Khanna M and Aggarwal A. As the results indicate, the highest juice volume was obtained from pectinase-treated lemon fruit, which might be due to the presence of solubility of pectin in lemon fruit [46, 47]. Today, industrial enzyme technology relies on microbial sources such as bacteria and yeasts. 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. [QxMD MEDLINE Link].

Harnessing the potential use of cellulolytic Klebsiella oxytoca (M21WG) and Klebsiella sp. the background of the blue DTC agar. The inoculating loop tool was sterilized with a bunsen burner flame. [31 0 R] 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. << 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. Biomed Res Int. In this exercise, there were about 16 different possible bacteria that could have been 2016;5(1):51421. J Agric Food Chem.
