\opening{Dear Editor,}
|
|
% \begin{doublespacing}
|
|
|
|
We are pleased to submit our manuscript, \textbf{``MANUSCRIPT TITLE''},
|
|
for consideration at \textbf{\emph{JOURNAL}}.
|
|
|
|
Among all algal-derived taste-and-odor compounds, 2-methylisoborneol
|
|
(MIB) stands out as the most notorious and widespread offender. Since
|
|
its initial identification, nearly 300 documented MIB-related odor
|
|
outbreaks have been reported globally. With an exceptionally low odor
|
|
threshold (10 ng L\textsuperscript{-1}), MIB imparts a distinct
|
|
earthy-musty smell that is immediately detectable in drinking
|
|
water---transforming it from a mere water quality parameter into a
|
|
critical public concern capable of triggering widespread complaints
|
|
during outbreaks.
|
|
|
|
The partitioning of MIB between intracellular and extracellular
|
|
compartments critically determines treatment strategy selection. When
|
|
MIB is primarily intracellular, conventional treatment processes such as
|
|
coagulation-sedimentation can achieve cost-effective removal. However,
|
|
when MIB becomes predominantly extracellular, utilities must implement
|
|
advanced treatment options like ozone-activated carbon - a significantly
|
|
more expensive approach that remains unavailable at many facilities.
|
|
This fundamental distinction creates a critical decision point for water
|
|
treatment optimization, where accurate prediction of MIB partitioning
|
|
directly impacts both operational efficiency and treatment costs.
|
|
|
|
Yet, current research and monitoring practices overlook a key
|
|
limitation: most studies and water treatment plants measure only total
|
|
MIB concentrations, assuming a fixed intracellular/extracellular ratio.
|
|
This oversimplification leads to suboptimal process selection, unstable
|
|
removal efficiency, and, in some cases, exacerbates MIB release through
|
|
inappropriate treatment.
|
|
|
|
Our study systematically investigates the dynamic partitioning of MIB
|
|
between intracellular and extracellular compartments through controlled
|
|
experiments with two major MIB-producing cyanobacteria
|
|
(\emph{Pseudanabaena} and \emph{Planktothricoides}). We demonstrate that
|
|
the extracellular fraction exhibits distinct growth phase-dependent
|
|
patterns, where crowding effects during rapid growth phases trigger
|
|
substantial MIB release. Building on these observations, we developed a
|
|
\textbf{mechanistic model} based on logistic growth dynamics that
|
|
quantitatively predicts MIB release patterns across the complete
|
|
cyanobacterial life cycle.
|
|
|
|
Our model's application to Lake Taihu's MIB outbreaks uncovered novel
|
|
spatiotemporal patterns in cyanobacterial populations responsible for
|
|
odorant production. More significantly, we established a predictive risk
|
|
assessment framework that pinpoints key environmental drivers
|
|
controlling both MIB occurrence and its release dynamics. This framework
|
|
enables proactive identification of high-risk conditions preceding major
|
|
release events.
|
|
|
|
Key Findings of this study include:
|
|
|
|
\begin{enumerate}
|
|
\def\labelenumi{\arabic{enumi}.}
|
|
\item
|
|
Crowding effects during cellular growth govern MIB partitioning.
|
|
\item
|
|
The model successfully forecasts large-scale MIB release events.
|
|
\item
|
|
It provides actionable guidance for optimizing water treatment
|
|
processes.
|
|
\end{enumerate}
|
|
|
|
To our knowledge, this is the first mechanistic framework explaining
|
|
growth-dependent MIB release dynamics. Importantly, our approach shows
|
|
promise for modeling other algal metabolites (e.g., geosmin,
|
|
cyanotoxins), offering broader implications for water quality
|
|
management.
|
|
|
|
We believe this study will interest researchers working on algal
|
|
metabolites, water treatment engineers, and resource managers addressing
|
|
cyanobacterial blooms. The combination of fundamental insights and
|
|
practical applications aligns well with \textbf{\emph{JOURNAL}}'s
|
|
mission to bridge scientific discovery and environmental technology.
|
|
|
|
To ensure a thorough and expert evaluation of our manuscript, we suggest
|
|
the following potential reviewers with specialized expertise in algal
|
|
metabolites, water treatment technologies, and cyanobacterial ecology.
|
|

|
