New materials of Sphinxiocarpon,a seed-like organ of putative lycopsid affinity,from the Late Devonian of Hubei,China

New materials of a seed-like organ, Sphinxiocarpon wuhanium (Li, Hilton et Hemsley) Wang, Xue et Prestianni, from the lower part of the Wutung Formation (Frasnian) at Xiannüshan Quarry of Wuhan, eastern Hubei, China provide new insights into its dehiscence mechanism. It is suggested that the oblique, longitudinally striated fibers within the sporophyll tissue serve as a structural mechanic to dehisce, and that the fimbriately opened apex of S. wuhanium is likely a result of the tissular dissolution and mechanical dynamics within its sporophyll and sporangial wall when it becomes mature. Sphinxiocarpon Wang, Xue et Prestianni, neither a seed nor a preovule, has the closest affinity to lycopsids and might represent an aberrant developmental form and/or an ecological adaptation to the local adversity.     

Ether phospholipids govern ferroptosis

Ferroptosis is a cell death modality triggered by excessive lipid peroxidation. Two recent studies(Zou et al.,2020; Cui et al., 2021) not only reveal critical roles of ether-linked phospholipids as an additional source for providing polyunsaturated fatty acid-containing phospholipids in driving ferroptosis but also suggest a context-dependent role of TMEM189-mediated vinyl-ether phospholipid(plasmalogen) synthesis in ferroptosis.     

Quantification of power consumption and oxygen transfer characteristics of a stirred miniature bioreactor for predictive fermentation scale-up

Miniature parallel bioreactors are becoming increasingly important as tools to facilitate rapid bioprocess design. Once the most promising strain and culture conditions have been identified a suitable scale-up basis needs to be established in order that the cell growth rates and product yields achieved in small scale optimization studies are maintained at larger scales. Recently we have reported on the design of a miniature stirred bioreactor system capable of parallel operation [Gill et al. (2008); Biochem Eng J 39:164-176]. In order to enable the predictive scale-up of miniature bioreactor results the current study describes a more detailed investigation of the bioreactor mixing and oxygen mass transfer characteristics and the creation of predictive engineering correlations useful for scale-up studies. A Power number of 3.5 for the miniature turbine impeller was first established based on experimental ungassed power consumption measurements. The variation of the measured gassed to ungassed power ratio, P(g)/P(ug), was then shown to be adequately predicted by existing correlations proposed by Cui et al. [Cui et al. (1996); Chem Eng Sci 51:2631-2636] and Mockel et al. [Mockel et al. (1990); Acta Biotechnol 10:215-224]. A correlation relating the measured oxygen mass transfer coefficient, k(L)a, to the gassed power per unit volume and superficial gas velocity was also established for the miniature bioreactor. Based on these correlations a series of scale-up studies at matched k(L)a (0.06-0.11 s(-1)) and P(g)/V (657-2,960 W m(-3)) were performed for the batch growth of Escherichia coli TOP10 pQR239 using glycerol as a carbon source. Constant k(L)a was shown to be the most reliable basis for predictive scale-up of miniature bioreactor results to conventional laboratory scale. This gave good agreement in both cell growth and oxygen utilization kinetics over the range of k(L)a values investigated. The work described here thus gives further insight into the performance of the miniature bioreactor design and will aid its use as a tool for rapid fermentation process development.
