微生物絮凝剂ZS-7的纯化及其结构特征研究

采用透析、乙醇沉淀、凝胶过滤层析对微生物絮凝剂ZS-7进行了纯化.经鉴定纯化后的微生物絮凝剂ZS-7是一种新型的糖蛋白,其产量大约为0.98 g/L发酵液.ZS-7主要由多糖和蛋白质组成,含量分别为91.5%和8.4%.进一步的分析表明ZS-7中含有酸性多糖包括糖醛酸(16.4%)、丙酮酸(7.1%)和乙酸(0.5%).采用凝胶色谱法测得ZS-7的相对分子质量为6.89×104.红外光谱、X射线能谱图和核磁共振图谱说明糖蛋白絮凝剂ZS-7含有羟基、氨基、羧基、甲氧基和磺酸等功能性基团.单糖组成分析说明ZS-7主要由鼠李糖、甘露糖、葡萄糖和半乳糖组成,各单糖的摩尔比大致为:半乳糖∶葡萄糖∶甘露糖∶鼠李糖=142∶2.2∶4.5∶3.4.     

金鱼藻对14CO2的吸收和积累动态

为了探明14CO2(14C)在环境中的行为,采用同位素示踪技术研究了金鱼藻对14CO2的吸收和积累动态,并探讨了金鱼藻作为监测大气14CO2污染指示植物的可能性.结果表明,生长在水中的金鱼藻会通过某些途径吸收空气中14CO2并形成积累趋势,吸收途径主要是金鱼藻通过光合作用从水体中吸收游离14CO2和H14CO3-.金鱼...

Societal implications of sustainable energy action plans: from energy modelling to stakeholder learning

This article investigates the potential impact of sustainable energy action plans (SEAPs) on local development through a two-step methodology involving participatory planning and quantitative analysis. The first phase relies on a participatory system mapping (PSM) approach and generates a causal structure at the basis of the urban model. In the second phase, we transform the qualitative map into a system dynamic model which evaluates the effect of the SEAP on social, economic and environmental indicators. This methodology was applied to the case of Cascina Municipality (Italy). Through scenario analysis, we show that some indirect feedback can harm the achievement of the 20% emission reduction target. This process allows the local authority and stakeholders to evaluate the impact of emission reduction policies on CO₂ emissions and local development, thereby generating collective learning on the systemic implications of the plan. We show that this method can enhance the ambition of emission mitigation efforts by small towns.

Scenario-based assessment and multi-objective optimization of urban development plan with carrying capacity of water system

• Impact of urban development on water system is assessed with carrying capacity. • Impacts on both water resource quantity and environmental quality are involved. • Multi-objective optimization revealing system trade-off facilitate the regulation. • Efficiency, scale and structure of urban development are regulated in two stages. • A roadmap approaching more sustainable development is provided for the case city. Environmental impact assessments and subsequent regulation measures of urban development plans are critical to human progress toward sustainability, since these plans set the scale and structure targets of future socioeconomic development. A three-step methodology for assessing and optimizing an urban development plan focusing on its impacts on the water system was developed. The methodology first predicted the pressure on the water system caused by implementation of the plan under distinct scenarios, then compared the pressure with the carrying capacity threshold to verify the system status; finally, a multi-objective optimization method was used to propose regulation solutions. The methodology enabled evaluation of the water system carrying state, taking socioeconomic development uncertainties into account, and multiple sets of improvement measures under different decisionmaker preferences were generated. The methodology was applied in the case of Zhoushan city in South-east China. The assessment results showed that overloading problems occurred in 11 out of the 13 zones in Zhoushan, with the potential pressure varying from 1.1 to 18.3 times the carrying capacity. As a basic regulation measure, an environmental efficiency upgrade could relieve the overloading in 4 zones and reduce 9%‒63% of the pressure. The optimization of industrial development showed that the pressure could be controlled under the carrying capacity threshold if the planned scale was reduced by 24% and the industrial structure was transformed. Various regulation schemes including a more suitable scale and structure with necessary efficiency standards are provided for decisionmakers that can help the case city approach a more sustainable development pattern.
