[PMID: 32827817 DOI: 10.1016/j.scitotenv.2020.141605] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/26/2020] [Revised: 08/07/2020] [Accepted: 08/08/2020] [Indexed: 06/11/2023]
Abstract
Harmful algal blooms (HABs) represent a growing threat to aquatic ecosystems and humans. Effective HAB management and mitigation efforts strongly rely on the availability of timely and in-situ tools for the detection of microalgae. In this sense, nucleic acid-based (molecular) methods are being considered for the unequivocal identification of microalgae as an attractive alternative to the currently used time-consuming and laboratory-based light microscopy techniques. This review provides an overview of the progress made on new molecular biotechnological tools for microalgal detection, particularly focusing on those that combine a nucleic acid (DNA or RNA) amplification step with detection. Different types of amplification processes (thermal and isothermal) and detection formats (e.g. microarrays, biosensors, lateral flows) are presented, and a comprehensive overview of their advantages and limitations is provided Although isothermal techniques are an attractive alternative to thermal amplification to reach in-situ analysis, further development is still required. Finally, current challenges, critical steps and future directions of the whole analysis process (from sample procurement to in-situ implementation) are described.

Abstract
This review presents a critical assessment of emerging microfluidic technologies for the application on biological productions of biofuels and other chemicals from microalgae. Comparisons of cell culture designs for the screening of microalgae strains and growth conditions are provided with three categories: mechanical traps, droplets, or microchambers. Emerging technologies for the in situ characterization of microalgae features and metabolites are also presented and evaluated. Biomass and secondary metabolite productivities obtained at microscale are compared with the values obtained at bulk scale to assess the feasibility of optimizing large-scale operations using microfluidic platforms. The recent studies in microsystems for microalgae pretreatment, fractionation and extraction of metabolites are also reviewed. Finally, comments toward future developments (high-pressure/-temperature process; solvent-resistant devices; omics analysis, including genome/epigenome, proteome, and metabolome; biofilm reactors) of microfluidic techniques for microalgae applications are provided.

A novel portable filtration system for sampling and concentration of microorganisms: Demonstration on marine microalgae with subsequent quantification using IC-NASBA. HARMFUL ALGAE 2018; 75:94-104. [PMID: 29778229 DOI: 10.1016/j.hal.2018.03.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/09/2018] [Revised: 03/19/2018] [Accepted: 03/24/2018] [Indexed: 06/08/2023]
Abstract
This paper presents a novel portable sample filtration/concentration system, designed for use on samples of microorganisms with very low cell concentrations and large volumes, such as water-borne parasites, pathogens associated with faecal matter, or toxic phytoplankton. The example application used for demonstration was the in-field collection and concentration of microalgae from seawater samples. This type of organism is responsible for Harmful Algal Blooms (HABs), an example of which is commonly referred to as "red tides", which are typically the result of rapid proliferation and high biomass accumulation of harmful microalgal species in the water column or at the sea surface. For instance, Karenia brevis red tides are the cause of aquatic organism mortality and persistent blooms may cause widespread die-offs of populations of other organisms including vertebrates. In order to respond to, and adequately manage HABs, monitoring of toxic microalgae is required and large-volume sample concentrators would be a useful tool for in situ monitoring of HABs. The filtering system presented in this work enables consistent sample collection and concentration from 1 L to 1 mL in five minutes, allowing for subsequent benchtop sample extraction and analysis using molecular methods such as NASBA and IC-NASBA. The microalga Tetraselmis suecica was successfully detected at concentrations ranging from 2 × 105 cells/L to 20 cells/L. Karenia brevis was also detected and quantified at concentrations between 10 cells/L and 106 cells/L. Further analysis showed that the filter system, which concentrates cells from very large volumes with consequently more reliable sampling, produced samples that were more consistent than the independent non-filtered samples (benchtop controls), with a logarithmic dependency on increasing cell numbers. This filtering system provides simple, rapid, and consistent sample collection and concentration for further analysis, and could be applied to a wide range of different samples and target organisms in situations lacking laboratories.

Abstract
This paper demonstrates a new method for electrochemical detection of specific sequences of DNA present in trace amounts in serum or blood. This method is designed for use at the point-of-care (particularly in resource-limited settings). By combining recombinase polymerase amplification (RPA)- an isothermal alternative to the polymerase chain reaction - with an electroactive mediator, this electrochemical methodology enables accurate detection of DNA in the field using a low-cost, portable electrochemical analyzer (specifically designed for this type of analysis). This handheld device has four attributes: (1) It uses disposable, paper-based strips that incorporate screen-printed carbon electrodes; (2) It accomplishes thermoregulation with ±0.1 °C temperature accuracy; (3) It enables electrochemical detection using a variety of pulse sequences, including square-wave and cyclic voltammetry, and coulometry; (4) It is operationally simple to use. Detection of genomic DNA from Mycobacterium smegmatis (a surrogate for M. tuberculosis-the main cause of tuberculosis), and from M. tuberculosis itself down to ∼0.040 ng/μL provides a proof-of-concept for the applicability of this method of screening for disease using molecular diagnostics. With minor modifications to the reagents, this method will also enable field monitoring of food and water quality.

Abstract
Nucleic acid sequence-based amplification (NASBA) is a sensitive and efficient molecular tool for amplification of RNA and has been widely adopted in clinical diagnostics. Monitoring of water and other environmental samples demands sensitive techniques, as potential pathogens may be in low concentrations and require only a few infectious units to infect their host. NASBA has qualities that should be advantageous for analysis of environmental samples, such as short reaction times, high sensitivity, and not readily affected by inhibitory substances that are often abundant in environmental samples. NASBA is well suited for incorporation into lab-on-a-chip (LOC) devices, as part of analysis systems that can be taken into the field for on-site screening. In this review, we explore advantages and drawbacks of NASBA as a tool for environmental analyses, and try to answer the question of whether it will be a recognised technique in the same manner as in clinical diagnostics.

Abstract
Isothermal amplification of nucleic acids is a simple process that rapidly and efficiently accumulates nucleic acid sequences at constant temperature. Since the early 1990s, various isothermal amplification techniques have been developed as alternatives to polymerase chain reaction (PCR). These isothermal amplification methods have been used for biosensing targets such as DNA, RNA, cells, proteins, small molecules, and ions. The applications of these techniques for in situ or intracellular bioimaging and sequencing have been amply demonstrated. Amplicons produced by isothermal amplification methods have also been utilized to construct versatile nucleic acid nanomaterials for promising applications in biomedicine, bioimaging, and biosensing. The integration of isothermal amplification into microsystems or portable devices improves nucleic acid-based on-site assays and confers high sensitivity. Single-cell and single-molecule analyses have also been implemented based on integrated microfluidic systems. In this review, we provide a comprehensive overview of the isothermal amplification of nucleic acids encompassing work published in the past two decades. First, different isothermal amplification techniques are classified into three types based on reaction kinetics. Then, we summarize the applications of isothermal amplification in bioanalysis, diagnostics, nanotechnology, materials science, and device integration. Finally, several challenges and perspectives in the field are discussed.

Abstract
Sustained observations (SOs) have provided invaluable information on the ocean's biology and biogeochemistry for over 50 years. They continue to play a vital role in elucidating the functioning of the marine ecosystem, particularly in the light of ongoing climate change. Repeated, consistent observations have provided the opportunity to resolve temporal and/or spatial variability in ocean biogeochemistry, which has driven exploration of the factors controlling biological parameters and processes. Here, I highlight some of the key breakthroughs in biological oceanography that have been enabled by SOs, which include areas such as trophic dynamics, understanding variability, improved biogeochemical models and the role of ocean biology in the global carbon cycle. In the near future, SOs are poised to make progress on several fronts, including detecting climate change effects on ocean biogeochemistry, high-resolution observations of physical-biological interactions and greater observational capability in both the mesopelagic zone and harsh environments, such as the Arctic. We are now entering a new era for biological SOs, one in which our motivations have evolved from the need to acquire basic understanding of the ocean's state and variability, to a need to understand ocean biogeochemistry in the context of increasing pressure in the form of climate change, overfishing and eutrophication.
