The goal of this project is to study the protein CowN in the diazotroph Azotobacter vinelandii (Av) in comparison to CowN in Gluconacetobacter diazotrophicus (Gd). Nitrogenase is an enzyme that catalyzes the reduction of nitrogen gas into ammonia in diazotrophic bacteria. In many diazotrophs, the protein CowN prevents nitrogenase inhibition from the environmental gas carbon monoxide (CO). Previous work studied CowN in the diazotroph G. diazotrophicus. In G. diazotrophicus, CowN binds to nitrogenase and weakens CO binding to its active site. The mechanism of CowN has only been investigated in G. diazotrophicus. Thus, we are interested in determining if CowN's …

Food and Machinery
[Objective] To investigate the effect of oil phase unsaturation degree on the performance of capsaicin emulsion to optimize its application efficacy in food systems.[Methods] Flaxseed oil (α-linolenic acid ),sunflower oil (linoleic acid ),and camellia oil (oleic acid ) are selected to construct the emulsion systems.The particle size distribution,zeta potential,microstructure,in vitro digestion stability,and sensory characteristics are systematically analyzed.[Results] The camellia oil emulsion exhibits the largest value in average particle size of specific surface area,while the flaxseed oil emulsion demonstrates the smallest particle size and significantly higher absolute zeta potential values (P<0.01).Its compact interfacial structure maintains smaller particle sizes throughout the digestion process (P<0.01),ensuring the optimal protection of capsaicin.According to sensory evaluation,the flaxseed oil emulsion has the strongest spicy perception,potentially attributed to its high unsaturation degree.[Conclusion] The findings demonstrated that the stability of capsaicin emulsions correlates with the unsaturation degree of the oil phase.Highly unsaturated fatty acids enhance emulsion stability by forming viscoelastic interfacial films.Flaxseed oil,with the highest unsaturation degree,produces emulsion with the smallest particle size,most uniform distribution,and best emulsion stability and pungency intensity.

Owing to the low allergenicity and high digestibility,rice bread has become an important alternative product to traditional wheat bread.However,the molecular characteristics of rice make it challenging for rice to form a continuous viscoelastic network akin to gluten.Consequently,the gas retention efficiency of rice dough is substantially diminished,resulting in quality degradation problems in rice bread,such as inadequate flavor,textural hardening,crumbling,and easy staling.To this end,both domestic and international scholars have examined the variations in the moisture content,texture,color,and flavor of rice bread.Meanwhile,various strategies for quality enhancement are summarized,including the selection and pretreatment of raw materials,exogenous improvement,sourdough fermentation technology,frozen dough techniques,and innovative baking technology.Finally,an experimental reference …
