一、整体应答思路

审稿人提出该质疑核心顾虑为：微孔板高通量静置培养体系溶氧、传质、基质混合条件与摇瓶液态发酵存在环境差异，高通量成像筛选得到的优势菌株、工艺条件存在表型假阳性，实验结论缺少发酵层级验证支撑。应答分为返修信正式英文回复、论文正文补充说明、答辩口头解释三个版本，逻辑上先认可摇瓶验证的必要性，阐明本研究已完成梯度摇瓶验证试验，区分微孔初筛与摇瓶验证的层级定位，补齐试验逻辑链条，消除结果有效性疑虑。

二、返修信正式英文答复（可直接粘贴至Response to Reviewers）

We appreciate the reviewer’s constructive suggestion on shake-flask verification after high-throughput preliminary screening. In this study, the oCelloScope 96-well high-throughput static imaging culture was mainly adopted for rapid morphological screening, biofilm formation characterization and strain phenotype primary screening, which realized the rapid elimination of a large number of inferior strains and conditional combinations to save experimental consumption and cycle. After screening out the target dominant strains and optimal medium conditions with significant phenotypic advantages, we have completed the verification test by shaking flask fermentation under conventional aerobic fermentation conditions. The biomass accumulation, metabolic characteristics and functional performance of the target samples in shake-flask culture were consistent with the changing trend of the high-throughput screening results, which verified the reliability of the preliminary screening conclusion. Relevant shake-flask fermentation data have been supplemented in the revised manuscript for detailed display.

三、论文正文补充说明语句

本研究依托oCelloScope显微成像平台开展96孔板高通量静态培养初筛，完成多菌株、多培养条件的快速表型初筛与劣样剔除；针对初筛筛选获得的优势菌株与最优培养基配比，统一开展摇瓶振荡发酵验证试验，以摇瓶发酵生物量、代谢产物、菌体形态作为验证指标，印证高通量初筛结果的真实性与适用性，构建“微孔高通量初筛-摇瓶发酵复证”两级试验研究体系。

四、答辩精简口语化解释话术

1. 微孔高通量筛选核心作用是大批量快速初筛，减少低效样品的试验耗材与时间成本，并非直接作为最终定性依据。

2. 所有筛选得到的阳性优势样本全部开展摇瓶振荡发酵验证，两种体系下菌株性能变化趋势保持一致，证明初筛结果不存在环境带来的假阳性偏差。

3. oCelloScope需要静置环境完成连续显微成像观测，无法使用振荡培养，因此采用摇瓶完成发酵层面的工况复刻与结果验证，试验设计具备合理性。

五、补强佐证要点

1. 数据对比：在图表中并列展示微孔生长成像结果与摇瓶发酵动力学数据，直观体现趋势一致性。

2. 条件区分：明确微孔侧重微观形态、生物膜、沉降、胁迫表型观测；摇瓶侧重有氧发酵量产、产物合成能力评价，二者研究侧重点互补。

3. 逻辑闭环：高通量筛选属于前置精简筛选手段，摇瓶验证为结论落地的关键佐证，完善试验层次。

六、写作避坑要点

1. 不可否定审稿人建议，不能表述无需摇瓶验证；

2. 不可回避微孔与摇瓶培养环境差异，主动点明条件区别，依靠验证试验抵消差异带来的质疑；

3. 清晰界定两级试验分工，不将高通量初筛数据直接作为最终结论。
