“…Vymazal et al [21] used a light microscope to spatially assess and compare microbial community structural differences in a HF system. The foundation for another relatively simple method for the identification of microbial community structural shifts was first suggested by White et al [22] (as described in Morris et al [23]) where they introduced the concept of extracting and profiling phospholipids from microbial community cellular membranes, which lead to the further refinement of FAME (fatty acid methy ester profile) and PLFA (phospholipid-derived fatty acid profile) methodologies. More recently, specialized metagenomics sequencing equipment has been developed and is available in benchtop formats.…”

Abstract:The field of treatment wetlands (TWs) is rapidly expanding and, arguably, is tasked with studying and understanding one of the most complex water treatment systems available. Microbial communities are generally considered to be responsible for the majority of wastewater constituent degradation in TWs. However, they are also known to be spatially heterogeneous, temporally dynamic, as well as structurally and functionally diverse. Presented here is a meta-analysis of all peer reviewed TW journal articles which utilized a microbial community assessment methodology over the period of 1988 to July 2016. A total of 1101 papers were reviewed, 512 from 1988 to 2012, 215 of which included a microbial community assessment aspect and were subsequently classified as representing past research, and 589 from 2013 to July 2016, 196 of which were classified as representing current TW microbial community research. In general, TW microbial community research has increased over time, with a marked surge in the past four years. Microbial community structure is currently the most commonly used methodological type followed by activity, enumeration and function, respectively. Areas of research focus included nitrogen transformations (156), organic degradation (33), and emerging contaminants (32), with general characterization studies also accounting for a significant proportion (243). Microbial communities from a range of TW systems have been investigated over the last four years with meso-scale (10-1000 L) being the most commonly studied system size followed by large-scale (>100,000 L), micro-scale (<10 L), and pilot-scale (1000-100,000 L). Free water surface flow (SF), horizontal subsurface flow (HF), and vertical flow (VF) systems are being studied in approximately equal proportions with the majority of studies focused on gaining fixed media/biofilm samples for analysis (rather than from the rhizosphere or interstitial water). Looking at efforts from a regional perspective shows Asia to be publishing the majority of research with a main focus on VF systems and structural community assessment. European and North American studies are generally more evenly distributed among structure, function, activity, and enumeration with the majority of studies completed on HF systems. South America, Africa, and Oceania published fewer studies but focused on structural community assessment with a selection of HF, SF and VF investigations. Great strides are being made in the field of microbial community assessment in TWs with functional assessment methods being developed, better utilized, and being related directly to water treatment. The use of high-powered metagenomics sequencing such as Illumina HiSeq instrumentation is on the rise, as is the development and utilization of functional assays such as DNA microarrays and community level physiological profiling allowing for more complete community assessment. Used in concert with activity, enumeration and newly implemented stable isotope methodologies, the field of TWs is certainly moving a...

The soil microbial communities and growth of sweet potato are often affected by soil type. This study evaluated the variations in microbial communities of paddy and upland soils used for two sweet potato cultivars (Jinhongmi and Sinjami) cultivation by their fatty acid methyl ester (FAME). The pH, available P 2 O 5 , exchangeable K, Ca, and Mg of upland soil at the harvesting stage were significantly higher than those of paddy soil. The moisture content of paddy soil (28.5%) has increased by 6.7% as compared to upland soil (p < 0.001). The average microbial biomasses in paddy soil were approximately 2.8 times larger for arbuscular mycorrhizal fungi (AMF) and 1.4 -1.6 times larger for fungi, total bacteria, Gram-positive bacteria, total FAMEs, Gram-negative bacteria, and actinomycetes. In addition, The total FAMEs, Gram-positive bacteria, fungi, total bacteria, and AMF in Jinhongmi cultivated soils were significantly larger than those in Sinjami cultivated soils. AMF communities in paddy soil showed significantly larger than that in upland soil (p < 0.001) indicating AMF are potentially responsible for the microbial community differentiation between paddy and upland field. The tuber yield of sweet potato was 28% higher, respectively, in the paddy soil and Sinjami treatment than in the upland soil and Jinhongmi treatment. It was confirmed that the paddy field was more effective on the productivity of sweet potato and soil microbial biomass.
