Passive phloem loading and long-distance transport in a synthetic tree-on-a-chip [PDF]

open access: yes, 2017
Vascular plants rely on differences of osmotic pressure to export sugars from regions of synthesis (mature leaves) to sugar sinks (roots, fruits). In this process, known as M\"unch pressure flow, the loading of sugars from photosynthetic cells to the ...

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

open access: yesAdvanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...

The proton electrochemical gradient induces a kinetic asymmetry in the symport cycle of LacY. [PDF]

open access: yes, 2020
LacY catalyzes accumulation of galactosides against a concentration gradient by coupling galactoside and H+ transport (i.e., symport). While alternating access of sugar- and H+-binding sites to either side of the membrane is driven by binding and ...

Comparison of Plasmid yield between L.B. and using Molasses as a medium [PDF]

open access: yes, 2009
During the initial studies I have found that the molasses may be a good alternative to costly L.B media where one can manipulate the C/N ratio as per requirement of cell.

Role of potassium and nitrogen on sugar concentration of sugar beet

open access: yesAfrican Crop Science Journal, 2004
Sugar is obtained from root of sugar beet (Beta vulgaris L.) in addition to other sources. Three important economic parameters are often considered and these are root yield, sugar concentration in root juice and total sugar yield. All the three are affected by cropping period and use of fertilisers.
