D'Aguanno E, Altamura E, Mavelli F, Fahr A, Stano P, Luisi PL.
PMID: 25793278
Life (Basel). 2015 Mar 18;5(1):969-96. doi: 10.3390/life5010969.

How did primitive living cells originate? The formation of early cells, which were probably solute-filled vesicles capable of performing a rudimentary metabolism (and possibly self-reproduction), is still one of the big unsolved questions in origin of life. We have...

Bioprospecting of indigenous resources for the exploration of exopolysaccharide producing lactic acid bacteria.

Journal, genetic engineering & biotechnology

Phloem sap proteins from Cucurbita maxima and Ricinus communis have the capacity to traffic cell to cell through plasmodesmata.

Proceedings of the National Academy of Sciences of the United States of America

Balachandran S, Xiang Y, Schobert C, Thompson GA, Lucas WJ.
PMID: 9391168

In angiosperms, the functional enucleate sieve tube system of the phloem appears to be maintained by the surrounding companion cells. In this study, we tested the hypothesis that polypeptides present within the phloem sap traffic cell to cell from...

Intestinal permeation enhancers enable oral delivery of macromolecules up to 70 kDa in size.

European journal of pharmaceutics and biopharmaceutics : official journal of Arbeitsgemeinschaft fur Pharmazeutische Verfahrenstechnik e.V

Fein KC, Gleeson JP, Newby AN, Whitehead KA.

The decades-long effort to deliver peptide drugs orally has resulted in several clinically successful formulations. These formulations are enabled by the inclusion of permeation enhancers that facilitate the intestinal absorption of peptides. Thus far, these oral peptide drugs have...

Optimization of process parameters of self-purging microwave pyrolysis of corn cob for biochar production.

Heliyon

Quillope JCC, Carpio RB, Gatdula KM, Detras MCM, Doliente SS.

Microwave pyrolysis offers rapid and low-cost technology to upgrade agro-forestry residues to high-value products. I-optimal experimental design was used to determine the optimal combination of microwave power and exposure time to maximize biochar yield from corn cob. A validation...

Products Released from Structurally Different Dextrans by Bacterial and Fungal Dextranases.

Foods (Basel, Switzerland)

Pittrof SL, Kaufhold L, Fischer A, Wefers D.
PMID: 33530339
Foods. 2021 Jan 26;10(2). doi: 10.3390/foods10020244.

Dextran hydrolysis by dextranases is applied in the sugar industry and the medical sector, but it also has a high potential for use in structural analysis of dextrans. However, dextranases are produced by several organisms and thus differ in...
