Structure and diversity of microbial communities are an important research topic in biology, since microbes play essential roles in the ecology of various environments. Different DNA isolation protocols can lead to data bias and can affect results of next-generation sequencing. To evaluate the impact of protocols for DNA isolation from soil samples and also the influence of individual handling of samples, we compared results obtained by two researchers (R and T) using two different DNA extraction kits: (1) MO BIO PowerSoil® DNA Isolation kit (MO_R and MO_T) and (2) NucleoSpin® Soil kit (MN_R and MN_T). Samples were collected from six different sites on Okinawa Island, Japan. For all sites, differences in the results of microbial composition analyses (bacteria, archaea, fungi, and other eukaryotes), obtained by the two researchers using the two kits, were analyzed. For both researchers, the MN kit gave significantly higher yields of genomic DNA at all sites compared to the MO kit (ANOVA; P <0.006). In addition, operational taxonomic units for some phyla and classes were missed in some cases: Micrarchaea were detected only in the MN_T and MO_R analyses; the bacterial phylum Armatimonadetes was detected only in MO_R and MO_T; and WIM5 of the phylum Amoebozoa of eukaryotes was found only in the MO_T analysis. Our results suggest the possibility of handling bias; therefore, it is crucial that replicated DNA extraction be performed by at least two technicians for thorough microbial analyses and to obtain accurate estimates of microbial diversity.

Abstract Background The abaca (Musa textilis Née) is a fiber crop native to the Philippines with high economic value because of its fiber - the Manila hemp, known to be the strongest of all the natural fibers. DNA extraction in abaca is difficult due to its fibrous nature, high cellulose content and polyphenol compounds. Thus an optimized DNA extraction method is required for extracting high quality abaca DNA for next-generation sequencing applications. Results In this study, we have compared five different methods for the extraction of high molecular weight DNA from abaca leaves. The methods are the traditional CTAB method (Protocol 1), the CTAB with PVP method (Protocol 2), the CTAB with 0.3% β-mercaptoethanol method (Protocol 3), SDS-method (Protocol 4) and CTAB with Triton X-100 and PVP method (Protocol 5). Out of the five methods tested, traditional CTAB-method (Protocol 1), CTAB with 0.3% β-mercaptoethanol method (Protocol 3) and SDS-method (Protocol 4) have shown to be the most consistent in giving high molecular weight DNA with good yield and purity based on A260/A280 and A260/A230 absorption values. TissueLyserII was also utilized for homogenization for the three extraction protocols for applications in high-throughput DNA extraction. DNA from two abaca varieties were extracted using the CTAB with 0.3% β-mercaptoethanol method (Protocol 3) and were sent for NGS based on Illumina HiSeq platform having both passed the quality control for library preparation. Conclusion The CTAB with 0.3% β-mercaptoethanol method (Protocol 3) was found to be the simplest and most consistent method for extracting average yield DNA with high quality for NGS applications. The SDS-method (Protocol 4) was determined to have the shortest processing time and together with TissueLyserII is the most appropriate method for high-throughput extraction of abaca samples which will be useful for genotyping-by-sequencing (GBS) studies.

An increasing number of newborn screening laboratories in the United States and abroad are moving towards incorporating next-generation sequencing technology, or NGS, into routine screening, particularly for cystic fibrosis. As more programs utilize this technology for both cystic fibrosis and beyond, it is critical to identify appropriate DNA extraction methods that can be used with dried blood spots that will result in consistent, high-quality sequencing results. To provide comprehensive quality assurance and technical assistance to newborn screening laboratories wishing to incorporate NGS assays, CDC’s Newborn Screening and Molecular Biology Branch designed a study to evaluate the performance of nine commercial or laboratory-developed DNA extraction methods that range from a highly purified column extraction to a crude detergent-based no-wash boil prep. The DNA from these nine methods was used in two NGS library preparations that interrogate the CFTR gene. All DNA extraction methods including the cruder preps performed reasonably well with both library preps. One lower-concentration, older sample was excluded from one of the assay evaluations due to poor performance across all DNA extraction methods. When 84 samples, versus eight, were run on a flow cell, the DNA quality and quantity were more significant variables.
