Zhongguo youzhi, 2022 核桃蛋白是优质植物蛋白，但其溶解度较低，限制了其在食品中的应用。为拓宽核桃蛋白的应用范围，采用不同的蛋白酶（碱性蛋白酶、胃蛋白酶、胰蛋白酶、木瓜蛋白酶、中性蛋白酶）对核桃分离蛋白进行酶解，然后分析不同蛋白酶酶解产物的水解度、二级结构和功能性（溶解性、吸水性、吸油性、乳化特性和起泡特性）。结果表明：碱性蛋白酶酶解产物的水解度最高，为22.16%，其次是木瓜蛋白酶的，为20.06%，而胰蛋白酶的最低，为13.95%；FTIR结果显示这5种蛋白酶酶解产物的二级结构中均以β-折叠及β-转角为主；在pH 7.0时，

Effects of Biochar Application on Nitrogen and Phosphorus Availability in Soils: aReview [PDF]
, 2016 利用生物炭在贫瘠的土壤上培育出肥沃的"黑土"正成为土壤学家研究的热点.氮、磷等大量养分是衡量土壤肥力高低的重要指标,生物炭对其有效性影响表现出极大的复杂性.不同研究得出的结论不尽相同,关键是缺乏对其机制的深入研究.由于氮和磷的不合理利用还可能造成非点源污染而带来环境风险,再加之生物炭施用的不可逆性,必须确保生物炭在任何情况下都不会对土壤和环境带来不利的影响.为此,本文综述了生物炭添加对氮肥和磷肥在土壤-植物系统迁移转化过程中的作用,重点讨论了不同生物炭处理方式对土壤磷素吸附解吸和形态转化的影响 ...

Political Cycles, Electricity Policy, and Mexico's Economy
Latin American Policy, Volume 17, Issue 2, June 2026.ABSTRACT Electricity reform in Mexico should stimulate economic growth, improve energy efficiency, and reduce greenhouse gas emissions. This article evaluates the successes and failures of reform and draws lessons across political cycles by analyzing changes in political dynamics—often tied to policy reversals—and the legal framework during the pro ...

Effect of root exudate on behavirors of polycyclic aromatic hydrocarbons (PAHs) in mangrove sediments [PDF]
, 2016 红树林是生长在热带、亚热带海岸潮间带的木本植物群落，对维护河口、海滨生态平衡和保护环境等方面具有重要意义。近年来，大量污染物被排放到红树林湿地生态系统中，其中以多环芳烃（Polycyclicaromatichydrocarbons，PAHs）为代表的有机污染物最为明显。由于PAHs具有较强的致癌、致畸、致突变作用，使其极易在沉积物中被吸附固定，研究根系分泌物对沉积物中PAHs的活化作用，植物修复PAHs的根际响应机制及其在根际微环境中的降解机理，将为深入探讨PAHs在根际沉积物中的生物有效性 ...

Shuitu Baochi Xuebao, 2007 选择酸性紫色土,研究pH和有机酸对紫色土吸附镉的影响。结果表明,pH在1.0~5.0的范围内,Cd2 的解吸率从接近100%急剧降低到20.0%。当pH>5.0,Cd2 的解吸率缓慢下降。相对较低的有机酸浓度(≤10-3mol/L)限制了Cd2 解吸,而较高的有机酸浓度则增加了Cd2 的解吸。柠檬酸和醋酸在较高浓度(>10-3mol/L)时极大地促进了Cd2 的解吸,其次是苹果酸,最小的是酒石酸。
