Enzymatic Activity of Lactobacillus Grown in a Sweet Potato Base Medium

Enzymatic activity of Lactobacillus reuteri grown in a sweet potato based medium with the addition of metal ions

The effect of metal ions on the enzymatic activity of Lactobacillus reuteri was studied. The enzymatic activity was determined spectrophotometrically using the corresponding substrate. In the control group, L. reuteri MF14-C, MM2-3, SD2112, and DSM20016 produced the highest α-glucosidase (40.06 ± 2.80 Glu U/mL), β-glucosidase (17.82 ± 1.45 Glu U/mL), acid phosphatase (20.55 ± 0.74 Ph U/mL), and...

Evaluation of β-amylase Activity of Sweet Potato (Ipomoea batatas) Cultivated in Iran

Besides the high starch content, sweet potato contains endogenous amylases where the two Predominants are - and β-amylases. Sweet potato is thought to be a promising source of β -amylase since β -amylase is one of the major protein in the tubers. This investigation has focused on the properties of β amylase from white-flesh sweet potato that has been grown in Iran as a potential source for indu...

Acid Base Considerations in Stone-Age Farming Sweet Potato Eaters, Modern-Day Sweet Potato Eaters, and High-Protein Consumers

Net endogenous acid production (NEAP) can be estimated by a primarily anthropometry-dependent organic acid anion (OA) component and the particularly diet-dependent potential renal acid load (PRAL). However, there is evidence that certain foods may also impact on the OA component. Here, we discuss measurements of urinary 24-h OA excretion obtained in healthy subjects, against the background of r...

Induction of peroxidase activity by ethylene in sweet potato.

Detection of sweet potato virus C, sweet potato virus 2 and sweet potato feathery mottle virus in Portugal.

Field sweet potato plants showing virus-like symptoms, as stunting, leaf distortion, mosaic and chlorosis, were collected in southwest Portugal and tested for the presence of four potyviruses, sweet potato virus C (SPVC), sweet potato virus 2 (SPV2), sweet potato feathery mottle virus (SPFMV), sweet potato virus G (SPVG), and the crinivirus sweet potato chlorotic stunt virus (SPCSV).
