Science Letters:Culture of Spirulina platensis in human urine for biomass production and O_2 evolution

INTRODUCTION For long distance manned space missions, bio- logical life support systems (BLSS) have to be in- troduced into the life support system to achieve regeneration of nutrient matter (Volker and Frank, 2001). Recently, many kinds of subsystems within BLSS have been proposed and experimented on solely or jointly, which include mainly higher plant, aquatic organisms (Volker and Frank, 2001), micro- organisms and microalgae (Gros et al., 2003). Mi- croalgae were incorporated in …     

ATP content and biomass activity in sequential anaerobic/aerobic reactors

Specific ATP content of volatile solids was measured to characterize the sludge activity in a sequential anaerobic/aerobic wastewater treatment system, with an upflow anaerobic sludge blanket (UASB) reactor and a three-phase aerobic fluidized bed (AFB) reactor. The wastewater COD level was 2000(3000 mg/L in simulation of real textile wastewater. The ATP content and the specific ATP contents of volatile solids at different heights of the UASB reactor and those of the suspended and immobilized biomass in the AFB reactor were measured. In the UASB reactor, the maximum value of specific ATP (0.85 mg ATP/g VS) was obtained at a hydraulic retention time (HRT) 7.14 h in the blanket solution. In the AFB reactor, the specific ATP content of suspended biomass was higher than that of immobilized biomass and increased with hydraulic retention time reaching a maximum value of 1.6 mg ATP/g VS at hydraulic retention time 4.35 h. The ATP content of anaerobes in the UASB effluent declined rapidly under aerobic conditions following a 2nd-order kinetic model.

Towards alternative trajectories? Reconfigurations in the Dutch electricity regime

In the early 2000s Dutch electricity companies are increasingly investing in technologies that enable them to replace coal with biomass. Replacing large amounts of coal (up to 40%) requires the companies to invest in technological trajectories alternative to the ones they have supported over the past decades. This paper aims to understand why these incumbent firms in the Dutch electricity regime are developing alternatives. The second aim of the paper is to provide a way for assessing the potential of innovations. The paper does so by bringing together insights from literature on (socio-) technical regimes and insights from literature on technological and market niches (strategic niche management). The main conclusion is that both niche processes (at the level of experimenting with alternatives) and changes in the incumbent regime are necessary for understanding the innovation journey of a new technology. A two-by-two matrix is developed that can be used for both analysis and governance purposes.

巴音布鲁克高寒草甸不同群落类型的生物量

生物量是生态系统获取能量能力的集中体现, 对生态系统结构的形成具有十分重要的影响。草地生态系统是陆地生态系统分布最广的生态类型之一, 在全球变化中的作用非常重要。本文以新疆天山中部的巴音布鲁克高寒草甸为研究对象, 选取了黑花苔草(Carex melantha)、鬼见愁锦鸡儿(Caragana jubata)和线叶嵩草(Kobresia capillifolia) 3种典型的群落类型,开展了生物量研究。结果表明:①黑花苔草群落盖度最大, 为100%, 物种数最低, 每平方米拥有植物8种～11种。鬼见愁锦鸡儿群落盖度次之, 为86.14%, 物种组成丰富, 每平方米拥有植物12种～15种。线叶嵩草群落盖度最低, 55.7%, 每平方米拥有植物13种～16种;②各群落内部的物种丰富度与地上生物量之间无显著关系, 而群落间表现出负相关, 差异极显著;③黑花苔草群落的地下生物量最大, 线叶嵩草群落次之, 鬼见愁锦鸡儿群落最低, 分别为13 608.8g/m²、6 097.8g/m²和2 554.74g/m²;④3种群落的地下生物量呈现出“T”形分布的模式, 且集中分布在0cm～10cm的土层中;⑤3种群落的地上生物量与土壤含水量呈极显著正相关, 地下生物量受相对湿度影响较大,二者也呈极显著正相关。
