Fermentation, 2022 Pyrolytic aqueous condensate (PAC) might serve as a cost-effective substrate for microbial malic acid production, as it is an unused side stream of the fast pyrolysis of lignocellulosic biomass that contains acetol and acetate as potential carbon sources.

Gram-scale production of recombinant microbial enzymes in shake flasks [PDF]
FEMS Microbiology Letters, 2017 Heterologous production of recombinant proteins is a cornerstone of microbiological and biochemical research as well as various biotechnological processes. Yields and quality of produced proteins have a tremendous impact on structural and enzymology studies, development of new biopharmaceuticals and establishing new biocatalytic processes.

Obstructions to shake sliceness for links [PDF]
arXiv, 2021 Shake slice generalizes the notion of a slice link, naturally extending the notion of shake slice knots to links. There is also a relative version, shake concordance, that generalizes link concordance. We show that if two links are shake concordant, then their zero surgery manifolds are homology cobordant.

Floquet Topological States in Shaking Optical Lattices [PDF]
Phys. Rev. A 89, 061603 (2014), 2014 In this letter we propose realistic schemes to realize topologically nontrivial Floquet states by shaking optical lattices, using both one-dimension lattice and two-dimensional honeycomb lattice as examples. The topological phase in the two-dimensional model exhibits quantum anomalous Hall effect.

Frontiers in Bioengineering and Biotechnology, 2021 Cultivations of mammalian cells are routinely conducted in shake flasks. In contrast to instrumented bioreactors, reliable options for non-invasive, time-resolved monitoring of the culture status in shake flasks are lacking.

Metabolic Engineering of Escherichia coli for the Production of β-Nicotinamide Mononucleotide [PDF]
Shipin Kexue, 2023 A modular metabolic engineering for Escherichia coli was designed for efficient production of β-nicotinamide mononucleotide (β-NMN). First, eight enzymes involved in the shunt metabolic pathways of nicotinamide (NAM) and β-NMN were inactivated to reduce ...

Shaking Force Balancing of the Orthoglide [PDF]
In: Zeghloul S., Laribi M., Sandoval Arevalo J. (eds) Advances in
Service and Industrial Robotics. RAAD 2020. Mechanisms and Machine Science,
vol 84. Springer, pp.227-234, 2020, 2211-0984, 2020 The shaking force balancing is a well-known problem in the design of high-speed robotic systems because the variable dynamic loads cause noises, wear and fatigue of mechanical structures. Different solutions, for full or partial shaking force balancing, via internal mass redistribution or by adding auxiliary links were developed.

BMC Biotechnology, 2011 Background Dissolved oxygen tension (DOT) is an important parameter for evaluating a bioprocess. Conventional means to measure DOT in shake flasks using fixed Clark-type electrodes immersed in the bulk liquid are problematic, because they inherently ...
