E. myriochaetum was subject to conventional acid digestion to extract biogenic silica with a % yield remarkably higher (up to 3 times) than for other Equisetum sp. (i.e. E. Arvense). The surface area of the isolated silica was ∼400 m2/g, suitable for biotechnological applications. Biogenic silicon was obtained by magnesiothermic reduction.
Jun 24, 2017· The biorefinery of horsetail involved a hydroalcoholic extraction, followed by acid hydrolysis and calcination. The yield of the hydroalcoholic extract was 20.2%; however, the yields of monomeric sugars, heat energy and silica varied with the conditions used in each step of the process.

The new method was applied to a soil catena in the Black Forest in SW-Germany. The results of the sequential extraction indicate that most of the Si (98- 99%) is bound in primary and secondary silicates. Up to 1% of Si originates from the abiotic amorphous phase or from organic matter. Key Words Sequential extraction, amorphous silica, bio-opal

3 methodology for determining biogenic Si. In this study, we applied an approach based on continuous monitoring of Si and Al during a 0.5 M NaOH extraction [after Koning et al. (2002) and Barao et al (2014)] to a range of sam-~ ples taken along the land-ocean continuum and compared the results with the ones obtained when 0.1 M Na 2CO 3 extraction
Jul 29, 2011· The fluor PDMPO has been used to identify silica deposition in horsetail and to provide new insight into silicification in this plant. It was observed that silica deposition in horsetail exactly mirrored the known deposition of callose in the related fern and other plants.

The horsetail is a ground plant with the largest amount of silica, which allows it has several applications in medicine area (Des Marais et al., 2003). Researchers believe that the anti-bacterial and antiseptic medicinal properties associated with the plant are due to the high silica content.
Biogenic silica (bSi), also referred to as opal, biogenic opal, or amorphous opaline silica, forms one of the most widespread biogenic minerals.For example, microscopic particles of silica called phytoliths can be found in grasses and other plants. Silica is an amorphous metal oxide formed by complex inorganic polymerization processes. This is opposed to the other major biogenic minerals ...
The extraction of biogenic silica from sediment dissolves all forms silica in the sample. The silica components in sediment can be separated between diatoms, sponge spicules, and silicate minerals (Conley et al., 1993). Distinguishing the source of biogenic silica is possible because of the different dissolution rates of the silica components.
