Effects of phytase-supplemented fermentation and household processing on the nutritional quality of Lathyrus sativus L. seeds

Autor: Meseret Bekele Buta, Clemens Posten, Shimelis Admassu Emire, Ann-Katrin Meinhardt, Alexandra Müller, Ralf Greiner

Publikováno v: Heliyon, Vol 6, Iss 11, Pp e05484- (2020)

Grass pea (Lathyrus sativus L.) is commonly consumed in cooked, fermented, and roasted forms in Ethiopia. However, the impacts of household processing practices on its nutrients, antinutrients, and toxic compounds have not been adequately studied. Th

Lipophilic compounds, but not fucoxanthin, mediate the genotoxic effect of photoautotrophic grown Phaeodactylum tricornutum in Caco-2 and HT-29 cells

Autor: Andrea Gille, Rebecca Hollenbach, Andreas Trautmann, Manuel Rodriguez Gomez, Ralf Krüger, Stephan C. Bischoff, Clemens Posten, Karlis Briviba

Publikováno v: Journal of Functional Foods, Vol 64, Iss , Pp 103671- (2020)

Phaeodactylum tricornutum (P. triconutum) gained high interest for use in human nutrition. We aimed to investigate the effect of photoautotrophically cultivated Phaeodactylum tricornutum on genotoxicity, cytotoxicity, formation of reactive oxygen spe

A Linear Programming Approach for Modeling and Simulation of Growth and Lipid Accumulation of Phaeodactylum tricornutum

Autor: Clemens Posten, Robert Dillschneider

Publikováno v: Energies, Vol 6, Iss 10, Pp 5333-5356 (2013)

The unicellular microalga Phaeodactylum tricornutum exhibits the ability to accumulate triacylglycerols to a high specific content when nutrients are limited in the culture medium. Therefore, the organism is a promising candidate for biodiesel produc

Effect of Traditional Household Processes on Iron, Zinc and Copper Bioaccessibility in Black Bean (Phaseolus vulgaris L.)

Autor: Sabrina Feitosa, Ralf Greiner, Ann-Katrin Meinhardt, Alexandra Müller, Deusdélia T. Almeida, Clemens Posten

Publikováno v: Foods, Vol 7, Iss 8, p 123 (2018)

Micronutrient deficiencies are a major public health problem. Beans are an important plant-based source of iron, zinc and copper, but their absorption is reduced in the presence of anti-nutrients such as phytates, polyphenols and tannins. Soaking and
