Cell suspension cultures of lithospermum erythrorhizon produce a large quantity of shikonin derivatives (red naphthoquinone pigments) and a part of them are se creted into the medium. Because of the large volume of liquid medium and the lowconcentration of product in it, pigments recovery from medium becomes one of thekey problems in industrializing this technology. In this paper,three isolation methods──extraction, precipitation and adsorption were used to recover pigments from medium.It resulted that in comparision...

Cell suspension cultures of lithospermum erythrorhizon produce a large quantity of shikonin derivatives (red naphthoquinone pigments) and a part of them are se creted into the medium. Because of the large volume of liquid medium and the lowconcentration of product in it, pigments recovery from medium becomes one of thekey problems in industrializing this technology. In this paper,three isolation methods──extraction, precipitation and adsorption were used to recover pigments from medium.It resulted that in comparision with extraction, the tradrtional method, precipitation and adsorption simplified the downstream proccess,increased the recovery and accordingly the production cost was cut down greatly.

紫草细胞培养生产紫草色素,有一部分紫草色素外泌到培养液中.由于培养液体积大,产物含量低,因此如何将色素加以回收是该项技术产业化的关键之一.本文分别采用萃取法、沉淀法和吸附法研究色素回收问题.发现用沉淀法和吸附法代替传统萃取法提取培养液中的紫草色素,可使紫草细胞培养生产紫草色素产物提取等下游过程工艺简化,收率提高,成本降低.

Abstract Separations seriously affect the flow behavior of hydraulic machinery and is intimately connected with hydraulic losses. For the purpose of fixing separation losses in design, the paper proposes a way of calculating it, by approximately estimating the size of separation regions with the help of assumed dead water zones. Simultaneously the paper presents an engineering model whereby the scope of separation in the impellers and its location of initiation may be estimated. Study results show that whenever separation occurs, the effected zone will incessantly increases downstreams. Thus the location of separation initiation had a vital effect on the extent of separation at impeller's exit and also on the hydraulic losses. Figs 5 and refs 5.

分离的产生将严重影响水力机械的流动特性,流动分离与水力损失密切相关。为了在设计中确定流动分离损失,该文通过利用死水区假设近似计算分离区的大小,提出了一种近似计算分离损失的方法。同时,给出了一种利用进出口参数来确定转轮内部流动分离的分离尺度和起始位置的工程模型。研究结果表明,流动发生分离后,在流向下游的过程中分离区不断扩大。流动分离的起始位置对转轮出口的分离尺度及水力损失有很大的影响。图5参5

Expanded bed, a special case of fluidized bed, possesses both the characteristic of the fluidized bed, being capable of processing suspended solid-containing feed streams and that of the fixed bed, having liquid stream in plug-flow, low back-mixing and high separation efficiency.As a method of primary separation for proteins, expanded bed is used to replace three steps, i.e.solid-liquid separation, concentration and primary purification with advantages of high yield,low capital cost and short operation time, thus becoming a research focus in downstream processing of biotechnology. This paper reviewed recent developments of expanded bed adsorption, including 1. Principle: stability of bed classification, adsorption and columns, 2.Operation: adsorption, washing, elution and regeneration, 3. Hydrodynamic characteristics beexpansion and residence time distribution, and 4. Application in protein purification.
