摘要

Abstract <section xml:id="bit26479-sec-0001" numbered="no"> > The viability of large‐scale microalgae cultivation depends on providing optimal growth conditions, for which a key operational parameter is culture density. Using Synechocystis sp. PCC 6803, we conducted a series of fixed‐density, steady‐state experiments and one batch‐growth experiment to investigate the role of culture density on biomass production and light utilization efficiency. In all cases, the fixed‐density, steady‐state experiments and batch‐growth experiment showed good agreement. The highest biomass production rates (260?mg?L ?1 ?d ?1 ) and efficiency for converting light energy to biomass (0.80?μg (μmol photons) ?1 ) occurred together at a culture density near 760?mg?L ?1 , which approximately corresponded to the lowest culture density where almost all incident light was absorbed. The ratio of OD <sub>680</sub> /OD <sub>735</sub> increased with culture density up to the point of maximum productivity, where it plateaued (at a value of 2.4) for higher culture densities. This change in OD <sub>680</sub> /OD <sub>735</sub> indicates a photoacclimation effect that depended on culture density. Very high culture densities led to a sharp decline in efficiency of biomass production per photons absorbed, likely due to a combination of increased decay relative to growth, metabolic changes due to cell‐cell interactions, and photodamage due to mixing between regions with high light intensity and zero light intensity. </section> </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div class="translation abstracttxt"> <span class="zhankaihshouqi fivelineshidden" id="abstract"> <span>机译：</span><Abstract XMLNS =“http://www.wiley.com/namespaces/wiley”type =“main”xml：lang =“en”> <title type =“main”>抽象</ title> <section XML：ID =“Bit26479-SEC-0001”编号=“否”> >大规模微藻培养的可行性取决于提供最佳生长条件，其中关键操作参数是培养密度。使用 synechocystis </ i> sp。 PCC 6803，我们进行了一系列固定密度，稳态实验和一批生长实验，以研究培养密度对生物质生产和光利用效率的作用。在所有情况下，固定密度，稳态实验和批量生产实验表现出良好的一致性。最高的生物质生产速率（260？mg？l α1</ sup>Δd 1 </ sup>）和将光能转化为生物量的效率（0.80≤μg（μmolphons）<sup >α1/ sup>）在760×mgΔ1Δ1</ sup>附近发生在一起发生在一起，其大致对应于最低培养密度，其中几乎所有入射光被吸收。 OD <sub> 680 </ sub> / od <sub> 735 </ sub>的比例随着培养物密度而增加，达到最大生产率，在其柔韧性（以2.4的值为2.4）以获得更高的培养密度。 OD <sub> 680 </ sub> / od <sub> 735 </ sub>的这种变化表示取决于培养密度的光摄入效果。非常高的培养密度导致每光子产生的生物质产生效率的急剧下降，可能由于衰减增加而相对于生长增加，由于细胞 - 细胞相互作用，并且由于具有高光强度的区域之间的混合而导致的代谢变化。和零光强度。 </ p> </ section> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >著录项</h2> <ul> <li> <span class="lefttit">来源</span> <div style="width: 86%;vertical-align: text-top;display: inline-block;"> <a href='/journal-foreign-15017/'>《Biotechnology and Bioengineering》</a> <b style="margin: 0 2px;">|</b><span>2018年第2期</span><b style="margin: 0 2px;">|</b><span>共5页</span> </div> </li> <li> <div class="author"> <span class="lefttit">作者</span> <p id="fAuthorthree" class="threelineshidden zhankaihshouqi"> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Straka Levi&option=202" target="_blank" rel="nofollow">Straka Levi;</a> <a href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Rittmann Bruce E.&option=202" target="_blank" rel="nofollow">Rittmann Bruce E.;</a> </p> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zkzz" style="display: none;">展开▼</span> </div> </li> <li> <div style="display: flex;"> <span class="lefttit">作者单位</span> <div style="position: relative;margin-left: 3px;max-width: 639px;"> <div class="threelineshidden zhankaihshouqi" id="fOrgthree"> <p>Schoolof Sustainable Engineering and the Built EnvironmentArizona State UniversityTempe Arizona;</p> <p>Schoolof Sustainable Engineering and the Built EnvironmentArizona State UniversityTempe Arizona;</p> </div> <span class="z_kbtnclass z_kbtnclassall hoverxs" id="zhdw" style="display: none;">展开▼</span> </div> </div> </li> <li > <span class="lefttit">收录信息</span> <span style="width: 86%;vertical-align: text-top;display: inline-block;"></span> </li> <li> <span class="lefttit">原文格式</span> <span>PDF</span> </li> <li> <span class="lefttit">正文语种</span> <span>eng</span> </li> <li> <span class="lefttit">中图分类</span> <span><a href="https://www.zhangqiaokeyan.com/clc/180.html" title="生物工程学（生物技术）">生物工程学（生物技术）;</a></span> </li> <li class="antistop"> <span class="lefttit">关键词</span> <p style="width: 86%;vertical-align: text-top;"> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=culture density&option=203" rel="nofollow">culture density;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=growth kinetics&option=203" rel="nofollow">growth kinetics;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=light utilization efficiency&option=203" rel="nofollow">light utilization efficiency;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=microalgae&option=203" rel="nofollow">microalgae;</a> <a style="color: #3E7FEB;" href="/search.html?doctypes=4_5_6_1-0_4-0_1_2_3_7_9&sertext=Synechocystis sp.
