Summary: This study explores a novel approach for protein separations based on High Performance Countercurrent Membrane Purification (HPCMP), demonstrating the feasibility of achieving high selectivity and over 98% yield of proteins without significant pressure-driven flow. The results suggest the potential of utilizing HPCMP for high resolution separations in the preparation of biopharmaceuticals and natural protein products.

Summary: The effects of the [CuL2]Br-2 complex on PSII activity and chlorophyll fluorescence yield in spinach were investigated. The complex was found to inhibit photosynthetic oxygen evolution and the photoreduction of the primary quinone electron acceptor. The inhibition depended on the concentration of [CuL2]Br-2 and was not affected by artificial electron donors.

Summary: This study evaluates tangential flow ultrafiltration as an alternative method for producing protein hydrolysates. The results show that the membrane diafiltration process has the potential to efficiently separate and recover hydrolyzed protein, with a higher protein recovery yield compared to centrifugation and depth filtration methods. Additionally, protein hydrolysates obtained by membrane ultrafiltration exhibit slightly better heat and pH stability.

Summary: The barley cultivar Sarab 1 can continue photosynthesis under low iron conditions through a reduction in P700 over-reduction and an increase in non-appressed thylakoid membranes. In contrast, another cultivar, Ehimehadaka-1, preferentially supplies iron to photosystem I to maintain photosynthetic activity. These findings highlight the multiple strategies that barley species have for acclimating photosynthesis to iron deficiency.

Summary: Among all membrane processes, ultrafiltration is widely used for both aqueous filtrations and solvent-based solutions. However, the challenges of membrane contact with organic solvents, such as permeate flux, rejection values, and long-term stability, remain. This review examines the effects of solvents on the ultrafiltration process and focuses on membrane pre-treatment strategies. It provides valuable knowledge and insights into organic solvent ultrafiltration.

Summary: Photosynthetic light reactions require strict regulation under dynamic environmental conditions. Depending on environmental constraints, photoinhibition of either Photosystem II (PSII) or Photosystem I (PSI) occurs frequently. Repair of photodamaged PSI is very slow compared to that of PSII, leading to a functional imbalance between the two photosystems. In this study, we investigated the acclimation of photosynthesis to PSI-limited conditions, both in the short-term and long-term, after PSI-specific photoinhibition treatment. We found that short-term acclimation mechanisms were induced immediately after inhibition, while longer-term acclimation involved changes in the stromal redox system and increased abundance of ATP synthase and Cytochrome b6f. Acclimation to PSI-limited conditions restored the CO2 assimilation capacity of plants without major PSI repair. These findings demonstrate that plants efficiently acclimate to changes in the photosynthetic apparatus, which is crucial for their adaptation to adverse environmental conditions.

Summary: The study obtained MPI and MCC using UF and MF, respectively, and assessed the effect of diafiltration on the colloidal dissociation of casein micelles. Comparison of serum phases with and without whey protein revealed significant differences in ionic strength and soluble proteins in the final concentrates, indicating potential indicators of ingredient quality and functionality.

Summary: Oxidative phosphorylation is a promising target for treating Mycobacterium tuberculosis and other mycobacteria infections. The structure of the mycobacterial electron transport chain reveals the presence of several important components, including the orphan protein MSMEG_2064, acyl phosphati-dylinositol dimannoside, menaquinone, and a purine nucleoside triphosphate. These findings provide insights into the function and structure of the enzyme.

Summary: Jatropha curcas responds to drought by increasing thermal dissipation of excitation energy in both photosystems, temporarily down-regulating the quantum yields of both PSII and PSI. This helps protect the photosynthetic machinery and enables rapid recovery of photosynthetic capacity when water is available.

Summary: The UF/DF process is crucial for isolating canola protein from rapeseed meal. By using a multi-stage membrane system, the components of the mixture can be separated. Diafiltration, which dilutes the feed stream, requires a substantial amount of water. This study used a mechanistic model and a genetic algorithm to optimize the process variables and improve the performance of a four stage UF/DF system, resulting in a reduction in diafiltrate, an increase in purity, and an increase in dry matter content.

Summary: The study revealed that Ganoderma lucidum polysaccharides can extend swimming time, enhance endurance, and promote fatigue recovery, especially polysaccharides with molecular weights above 10 kDa. These GLPs may reduce the activities of SUN and CK, decrease the levels of MDA and BLA, increase the level of Gly, accelerate fat transformation, and improve the activities of GPx, SOD, and LDH in all treated mice. Therefore, GLPs above 10 kDa could be potential agents with antifatigue activity.
