TL;DR: Zhang et al. as discussed by the authors examined the influence of corruption and resource misallocation on ecological efficiency and found that corruption can directly reduce ecological efficiency; however, it can also intensify resource mis-allocation, which leads to further decline in ecological efficiency.

TL;DR: Marine yeast strain 1, isolated from the surface of a marine alga, was found to secrete a large amount of inulinase into the medium, indicating that the crude inulin enzyme had a high exoinulinase activity.
Abstract: Marine yeast strain 1, isolated from the surface of a marine alga, was found to secrete a large amount of inulinase into the medium. This marine yeast was identified as a strain of Pichia guilliermondii according to the results of routine yeast identification and molecular methods. The crude inulinase produced by this marine yeast worked optimally at pH 6.0 and 60°C. The optimal medium for inulinase production was seawater containing 4.0% (w/v) inulin and 0.5% (w/v) yeast extract, while the optimal cultivation conditions for inulinase production were pH 8.0, 28°C and 170 rpm. Under the optimal conditions, over 60 U ml−1 of inulinase activity was produced within 48 h of fermentation in shake flasks. A large amount of monosaccharides and a trace amount of oligosaccharides were detected after the hydrolysis, indicating that the crude inulinase had a high exoinulinase activity.

TL;DR: In this article, two cruises were carried out in the Changjiang (Yangtze River) Estuary and adjacent area in spring and summer, and the results of CHEMTAX calculation indicated that in spring diatoms and chlorophytes contribute equally to phytoplankton biomass, while phyto-ankton community structure is mainly composed of diatom in summer.
Abstract: Environmental factors in estuaries are highly variable in terms of both spatial and temporal dimensions and hence phytoplankton biomass, as well as community structure, is dynamic. Two cruises were carried out in the Changjiang (Yangtze River) Estuary and adjacent area in spring and summer. The result of CHEMTAX calculation suggests that in spring diatoms and chlorophytes contribute equally to phytoplankton biomass, while phytoplankton community structure is mainly composed of diatoms in summer. We encountered blooms in summer with chlorophyll a (CHLa) over 10 μg l−1 off the Changjiang Estuary and they were mainly caused by diatoms (>90%). Based on the HPLC analysis of samples collected, phytoplankton pigments mainly concentrated beyond the front between 122.5°E and 123°E where nutrients and turbidity were best balanced. Euphotic depth (Zeu, calculated from Secchi disk depth) to surface mixed layer depth (Zmix) ratio (i.e. Zeu/Zmix) were comparable in spring (average value 1.2) and the ratio increased to 5.2 in summer. Variation of the ratio indicates an apparent shift of light and physical conditions from spring to summer. Correspondingly, CHLa was positively related to Zeu/Zmix ratio (r2 = 0.83) in spring, indicating the light limitation over the whole investigation area. On the other hand, the relationship of CHLa and Zeu/Zmix ratio became unclear when Zeu/Zmix ratio >3 in summer. This is probably due to the combination of both light limitation before the front and nutrient limitation beyond the front. In addition, evidence was found that light condition can impact the diagnostic pigments in the Changjiang Estuary.

TL;DR: This review summarized the challenges toward the oral delivery systems including instability and poor permeability in gastrointestinal environment and recently developed chitosan-based nanocarriers administered via oral route were highlighted for protecting drugs against degradation, releasing drugs in small intestine, enhancing drug uptake, thus improving oral bioavailability.
