Comparison of different protocols for the extraction of microbial DNA from reef corals BJM
Santos,H.F.; Carmo,F.L.; Leite,D.C.A.; Jesus,H.E.; De Carvalho Maalouf,P.; Almeida,C.; Soriano,A.U.; Altomari,D.; Suhett,L.; Vólaro,V.; Valoni,E.; Francisco,M.; Vieira,J.; Rocha,R.; Sardinha,B.L.; Mendes,L.B.; João,R.R.; Lacava,B.; Jesus,R.F.; Sebastian,G.V.; Pessoa,A.; van Elsas,J.D.; Rezende,R.P.; Pires,D.O.; Duarte,G.; Castro,C.B.; Rosado,A.S.; Peixoto,R.S..
This study aimed to test different protocols for the extraction of microbial DNA from the coral Mussismilia harttii. Four different commercial kits were tested, three of them based on methods for DNA extraction from soil (FastDNA SPIN Kit for soil, MP Bio, PowerSoil DNA Isolation Kit, MoBio, and ZR Soil Microbe DNA Kit, Zymo Research) and one kit for DNA extraction from plants (UltraClean Plant DNA Isolation Kit, MoBio). Five polyps of the same colony of M. harttii were macerated and aliquots were submitted to DNA extraction by the different kits. After extraction, the DNA was quantified and PCR-DGGE was used to study the molecular fingerprint of Bacteria and Eukarya. Among the four kits tested, the ZR Soil Microbe DNA Kit was the most efficient with...

Comparison of DNA extraction protocols for microbial communities from soil treated with biochar BJM
Leite,D.C.A.; Balieiro,F.C.; Pires,C.A.; Madari,B.E.; Rosado,A.S.; Coutinho,H.L.C.; Peixoto,R.S..
Many studies have evaluated the effects of biochar application on soil structure and plant growth. However, there are very few studies describing the effect of biochar on native soil microbial communities. Microbial analysis of environmental samples requires accurate and reproducible methods for the extraction of DNA from samples. Because of the variety among microbial species and the strong adsorption of the phosphate backbone of the DNA molecule to biochar, extracting and purifying high quality microbial DNA from biochar-amended soil is not a trivial process and can be considerably more difficult than the extraction of DNA from other environmental samples. The aim of this study was to compare the relative efficacies of three commercial DNA extraction...
