“…No differences in [6]-gingerol were observed according to the type growth media. Investigation by Rodriguez et al (2006) on the effect of different substrates for hydroponic production of 'Galia' muskmelons (Cucumis melo L.) revealed that fruit quality and composition were not affected by substrate. Others studies also had showed that rising concentration of electric conductivity (EC) of nutrient solution and nutrient solution composition can caused increase in total soluble solids, organic acids and plant secondary metabolites for tomatoes (Petersen et al, 1998), sweet pepper and cucumber (Trajkova et al, 2006).…”

Ginger (Zingiber officinale Rosc.) belongs to a tropical and sub-tropicalZingiberaceae family, which originated from Southeast Asia. Ginger is one of themost widely used herbs contains several interesting bioactive constituentsincluding [6]-gingerol that has potent antioxidant activity and health promotingproperties. Substrates plays an important role for plants to growth in the soillessculture system. Given the nature of the substrate may play a crucial role indetermining water and nutrient availability for the plant and hence may affect themetabolic pathways involved in the synthesis of specific biochemical compounds,this study was conducted to determine the effects of organic soilless substrates suchas coir dust and burnt paddy husks on ginger growth, yield and [6]-gingerol contentusing soilless culture system. The treatments were arranged in a randomizedcomplete block design (RCBD) with five levels of treatment with three replicates.The treatments include, T1 = 100% coir dust; T2 = 100% burnt paddy husks; T3 =70% coir dust and 30% burnt paddy husks; T4 = 30% coir dust and 70% burntpaddy husks; and T5 = 50% coir dust and 50% burnt paddy husks. Results showedthat plant in T1 gave rise to highest rhizomes yield (5480  325 gm) compare toother treatments. Media containing high amount of coir dust (70 – 100%) showedgood growth and increased the rhizome yield up to 36% compared to thosecontaining high amount of burnt paddy husks. There was no significant differencebetween all treatments in term of [6]-gingerol content in the fresh and dry gingerrhizomes. The studies suggested that the secondary metabolites like [6]-gingerolcontent and accumulation were not affected by the substrates. It can be concludedthat 100% coir dust are the best substrates for growing ginger in soilless culturesystem.

“…The impact of the excessively high EC levels in the recycled solution on melon fruit setting could not be assessed in the present study, as only two fruits were left to mature in each plant, following common practices in early greenhouse crops of “Galia” melon ( Rodriguez et al, 2006). As reported by Mavrogiannopoulos et al (1999), moderately high salinity levels do not significantly affect the number of fruits per plant in melon, and mean fruit weight is more sensitive to salinity than the fruit number per plant.…”

Spatially Resolved Confocal Resonant Raman Microscopic Analysis of Anode‐Grown Geobacter sulfurreducens Biofilms

When grown on the surface of an anode electrode, Geobacter sulfurreducens forms a multi-cell thick biofilm in which all cells appear to couple the oxidation of acetate with electron transport to the anode, which serves as the terminal metabolic electron acceptor. Just how electrons are transported through such a biofilm from cells to the underlying anode surface over distances that can exceed 20 microns remains unresolved. Current evidence suggests it may occur by electron hopping through a proposed network of redox cofactors composed of immobile outer membrane and/or extracellular multi-heme c-type cytochromes. In the present work, we perform a spatially resolved confocal resonant Raman (CRR) microscopic analysis to investigate anode-grown Geobacter biofilms. The results confirm the presence of an intra-biofilm redox gradient whereby the probability that a heme is in the reduced state increases with increasing distance from the anode surface. Such a gradient is required to drive electron transport toward the anode surface by electron hopping via cytochromes. The results also indicate that at open circuit, when electrons are expected to accumulate in redox cofactors involved in electron transport due to the inability of the anode to accept electrons, nearly all c-type cytochrome hemes detected in the biofilm are oxidized. The same outcome occurs when a comparable potential to that measured at open circuit (-0.30 V vs. SHE) is applied to the anode, whereas nearly all hemes are reduced when an exceedingly negative potential (-0.50 V vs. SHE) is applied to the anode. These results suggest that nearly all c-type cytochrome hemes detected in the biofilm can be electrochemically accessed by the electrode, but most have oxidation potentials too negative to transport electrons originating from acetate metabolism. The results also reveal a lateral heterogeneity (x-y dimensions) in the type of c-type cytochromes within the biofilm that may affect electron transport to the electrode.

“…White spruce and fir bark alone or mixed with low-grade peat showed high potential for greenhouse tomato production and represented an environmentally sound alternative to rockwool [136]. Moreover, pine bark can be successfully used as a stand-alone substrate for the cultivation of vegetables, such as bell pepper, cucumbers, and muskmelons [137][138][139]. An economic analysis determined that pine bark was nearly one-eighth the cost of perlite and could be reused for several consecutive crops, resulting in reduced production costs and greater profits.…”

Increasing Sustainability of Growing Media Constituents and Stand-Alone Substrates in Soilless Culture Systems

Decreasing arable land, rising urbanization, water scarcity, and climate change exert pressure on agricultural producers. Moving from soil to soilless culture systems can improve water use efficiency, especially in closed-loop systems with a recirculating water/nutrient solution that recaptures the drain water for reuse. However, the question of alternative materials to peat and rockwool, as horticultural substrates, has become increasingly important, due to the despoiling of ecologically important peat bog areas and a pervasive waste problem. In this paper, we provide a comprehensive critical review of current developments in soilless culture, growing media, and future options of using different materials other than peat and rockwool. Apart from growing media properties and their performance from the point of view of plant production, economic and environmental factors are also important. Climate change, CO 2 emissions, and other ecological issues will determine and drive the development of soilless culture systems and the choice of growing media in the near future. Bioresources, e.g., treated and untreated waste, as well as renewable raw materials, have great potential to be used as growing media constituents and stand-alone substrates. A waste management strategy aimed at reducing, reusing, and recycling should be further and stronger applied in soilless culture systems. We concluded that the growing media of the future must be available, affordable, and sustainable and meet both quality and environmental requirements from growers and society, respectively.
