Drivers of bat researchers’ intent to adopt field hygiene practices

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Infectious disease is a growing threat to wildlife, with zoonotic transmission most likely at the human–wildlife interface. One underappreciated activity at this interface is fieldwork with wild animals, but associated risks can be mitigated through field hygiene (FH) practices, such as using personal protective equipment and other appropriate

Regulatory compliance and support for altered management of the exotic pet trade

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Globally, the exotic pet trade has contributed to species invasion, disease, and animal welfare risks. Although scientists have advocated for increased trade regulation, the success of management and regulatory efforts depends on compliance by participants in the exotic pet trade. We used a regulatory compliance framework to investigate exotic

微波辅助光催化降解4-氯酚的研究

open access: yesGongye shui chuli, 2004
采用了一种新的水处理技术微波辅助光催化(MW/UV/P25)降解4-氯酚(4CP)模拟废水。初始质量浓度为30mg/L的4CP在微波光催化下发生了降解,反应120min,4CP的降解率达到82.85%,Cl-质量浓度增加值为7.95mg/L。4CP的降解率与溶液的pH、通气条件、紫外灯光照度等因素有关,外加H2O2氧化剂能够加速4CP的降解。微波辅助光催化降解4CP服从一级反应动力学方程。

Overlap of nonbreeding wandering albatrosses with fisheries and implications for colony‐specific population trajectories at South Georgia

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Bycatch in fisheries is one of the most serious threats to pelagic seabirds, causing major population declines. Mitigation measures can reduce bycatch substantially, but many fisheries fail to apply best practices, and seabird mortality remains high.

对苯二甲酸废水厌氧反应酶竞争效应及应用

open access: yesGongye shui chuli, 2017
介绍了精对苯二甲酸(PTA)废水生化处理工艺流程、厌氧反应器运行状况及存在问题。研究了PTA废水中易降解脂肪酸浓度对于对苯二甲酸(TA)厌氧降解反应速率的影响,结果表明,乙酸等易降解脂肪酸对TA的厌氧降解反应有酶竞争性抑制作用;建立了废水中有易降解有机物存在时TA厌氧降解反应动力学方程并求得有关特征参数;提出了采取相应措施来解决厌氧反应器故障问题,取得良好效果。

Evaluating synthetic substitutes to reduce illegal harvesting and support species recovery

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Providing synthetic substitutes is a widely promoted strategy to shift consumer demand away from wildlife products derived from threatened species. Yet, there is little evidence on whether product substitution prevents illegal or unsustainable harvesting and contributes to the recovery of threatened populations.

高效苯酚降解菌群的选育及降解特性研究

open access: yesGongye shui chuli, 2017
通过富集驯化获得具有高效降解苯酚能力的苯酚降解菌群PDBC-1,对菌群降解苯酚的性能及影响因素进行了分析。结果表明,红球菌属细菌是该菌群中的优势菌种。在初始苯酚质量浓度低于1 200mg/L 时,菌群能够在72 h 内完全降解苯酚,但在更高苯酚浓度下,苯酚对菌群生长造成明显抑制,苯酚降解能力显著下降。该菌群降解苯酚的适宜盐度为0~5%,温度为25~40℃,pH 为7.0~8.0。

Polyphenol oxidase depletion in Nicotiana benthamiana enhances recombinant protein purification and preserves native protein integrity

open access: yesNew Phytologist, Volume 251, Issue 3, Page 1283-1293, August 2026.
Polyphenol oxidases (PPOs) depletion preserves endogenous proteins at their predicted molecular weights and enhances detectable enzymatic activities. (a) Less RbcL crosslinking in ppo mutant of Nicotiana benthamiana. Leaf extracts were incubated for 1 h, separated on protein gels, stained with Coomassie or analyzed by Western blot with the anti‐RbcL ...

蛋白酶体抑制剂对胶质瘤U251细胞增殖的抑制作用

open access: yesZhongguo shiyan zhenduanxue, 2011
细胞内存在两种蛋白降解的途径,一种是通过自噬途径降解大分子的蛋白,另一种是通过泛素-蛋白酶体途径降解,泛素-蛋白酶体(ubiquitin-proteasome system,UPS)途径是细胞内非溶酶体途径蛋白质降解通路,不仅降解变性、异常或起短暂作用的蛋白质,而且能降解转录因子 ...

高能电子束辐照降解枸杞中五种农药残留

open access: yesFushe yanjiu yu fushe gongyi xuebao
为探索绿色、高效降解枸杞中农药残留的方法,提高枸杞产品质量,本研究采用高能电子束辐照的方式处理啶虫脒、吡虫啉、毒死蜱、克百威、炔螨特5种农药污染的枸杞干果样品,利用超高效液相色谱质谱联用法检测辐照前后样品中农药残留的含量,同时探究不同含水率对辐照降解农药的影响。结果表明,当吸收剂量逐渐升高时,5种农药各自的最高降解率在12.9%~41.3%范围内,其中,啶虫脒在8 kGy时,降解率最高,达到41.3%,同一吸收剂量下,枸杞干果中啶虫脒含量越低,其降解率越高。吡虫啉、毒死蜱及克百威在4 ...
