We also demonstrate the importance of resin selection and thorough chromatography operation optimization by evaluating the cost benefit of maximizing resin binding capacity to target product. Of course, further work is needed to verify whether the use of column chromatography is needed. Transient production of thaumatin in the edible crop Spinacia oleracea was also economically competitive and …

Doubled haploids quickly provide largeamounts of seed for replicated field trials
Since these technologies are unlikely to be mission critical during Artemis, their TRL can be increased and their risk factors studied through in-space evaluation. The Artemis missions also provide a test bed to evaluate the space-based evolution of microbes and alterations of seed stocks as a risk inherent to the biological component of the biomanufactory. This risk …

Similar for trichloroethylene that was observed at extremely low levels indoors
The concentration of toluene in the building exhaust was 120 µg m-3, more than double the highest level measured indoors, suggesting a possible toluene source in the restrooms. The cleaning compound 2-butoxyethanol was slightly higher indoors, but at very low concentrations.The compounds listed in this category have many sources, including outdoor air. For the most …

These changes should be reflected in the concentration of various metabolites after exposure
Direct investigation of N2O production and fate in the soil profile has not advanced far, and is only beginning in the fertigation context. It is increasingly clear that much, if not most, soil N2O might be reduced before emission from surface. It is commonly assumed that the upper 20 cm play the central role in surface …
TEM images further substantiated the intact transport of NPs into plants
The [64Cu]-NP-uptake and accumulation amounts observed within lettuce seedlings were reasonable and comparable to others reports in the literature, reaching the same general conclusions that NP transport and accumulation in plants is species and size dependent.Smaller NPs have been demonstrated to have higher accumulation in plants than larger NPs. For example, Ni-NPs had very high NP …

We first established the glycoform distribution of rituximab derived from untreated plants
The process of Velaglucerase alpha was design to modify the glycosylation profile of the protein toward oligomannose N-glycans to improve mannose-receptor mediated uptake of the drug into macrophages, the target cells. Here, we determined the optimal concentration of kifunensine and demonstrate that kifunensine addition at a concentration of 0.375 µM in the Agrobacterium infiltration solution of …
Several hypotheses have been put forward to explain carbon dioxide acclimation
These products pass through an elaborate biochemical cycle that eventually forms one molecule of a 6-carbon sugar and regenerates RuBP. The reaction of RuBP with oxygen oxidizes the RuBP, splits it into one molecule of a 3-carbon compound and one molecule of a 2-carbon compound , and subsequently releases carbon dioxide, hence the names C2 pathway or, more …

Many microorganisms have the capacity to oxidize and precipitate Mn as manganate
The sensitivity of XRD profiles to the amount, coordination, and position of high-Z interlayer scatterers, and to the number of vacant layer sites is illustrated next.Except for one sample obtained by metal sorption on poorly crystalline Mn oxides , the new Zn-rich phyllomanganate contains higher amounts of vacant layer sites and transition elements than any other natural …

Currently very little information is available on how nanoparticles affect the soil microbial community
Plant growth and yield were modestly reduced but importantly, nitrogen fixation was almost entirely eliminated. Nodule content of ceria approached 11 mg kg−1 in some instances and electron microscopy confirmed the complete absence of symbiotic bacteria. Similarly, Hernandez-Viezcas et al.used synchrotron μXRF and μXANES to observe nanoceria within soybean root nodules and pods, although up …
Acidification helps to reduce the amount of bacteria that will grow on the media
Due to the rotational motion of the water, the levels of turbulence kinetic energy are increased leading to vigorous mixing and hence to uniform exposure to UV radiation. Since the UV lamps are arranged circumferentially around the outside of the quartz cylinder, pathogens that may become imbedded into suspended solids experience increasing probability of receiving …
