Removal of formaldehyde from indoor air by potted Sansevieria trifasciata plants: dynamic influence of physiological traits on the process

AbstractPlant-based removal of indoor formaldehyde is a widely studied method, yet little is known about the dynamic changes in this process. In this study, potted Sansevieria trifasciata Prain plants were exposed to 5-ppm formaldehyde gas concentration for 7 days. The results showed that formaldehyde exposure led to plant stress, affected photosynthesis, and damaged membrane lipids, as evidenced by a decrease in chlorophyll content, an increase in Chl a/b ratio and malondialdehyde content. However, the formaldehyde removal ability of the plants increased over the first 5 days, peaking at 18.02 mg h−1 kg−1 dry weight on the 5th day. This trend was correlated with changes in various indicators in the plant roots, including phytohormone and antioxidant enzymes. Notably, catalase activity in the roots behaved differently from other indicators. The indicators in the leaves showed turning points around the 3rd day due to the direct exposure of the leaves to formaldehyde. The relative abundance of endophytes indicated an increase in plant growth-promoting bacteria, which helped the plant cope with formaldehyde stress. The study suggests that under formaldehyde stress, plants manage active oxygen content by increasing phytohormones and regulating redox reactions. This enhances their tolerances to formaldehyde, thereby improving their ability to remove formaldehyde and aiding recovery after formaldehyde exposure. Graphical abstract

The influence of phytoncidal properties of indoor plants on the air microflora of preschool educational organizations

BACKGROUND: The quality of indoor air is an important factor affecting health. AIM: To study the effect of phytoncidal properties of indoor plants on closed space under normal operating conditions of preschool educational institutions. MATERIAL AND METHODS: The dynamics of the microorganisms’ total number in the air of group rooms of preschool educational institutions was assessed according to current guidelines. The rooms were identical in area. The radius of phytoncidal action of indoor plants was determined. Air samples were taken after a week of exposure at different distances from a group of these plants in the breathing zone of children using an aspiration method with a sampling device. Statistical processing was carried out using the Statistica 10.0 and Microsoft Excel packages, ANOVA analysis of variance was applied. RESULTS: Plant species with phytoncidal activity were selected and designated (Chlorophytum comosum, Aspidistra elatior, Begonia ricinifolia, Hibiscus rosa-sinensis, Kalanchoe blossfeldiana, Plectranthus scutellarioides, Murraya exotica, Nephrolepis, Sansevieria trifasciata, Cyperus alternifolius). The total number of microorganisms in the air of group rooms before and after the installation of phytoncidal plants was compared (1201 and 584 CFU/m3). The maximum radius of plant placement at which bacterial contamination of the air decreased was determined. It was found that within a radius of 5 m from the placement of plants, the number of microorganisms was in the range of 380–481 CFU/m3, more than 5 m — 728–1101 CFU/m3. CONCLUSION: The use of indoor plants with phytoncidal activity in closed spaces of organized children's groups can serve as an additional way to improve the quality of the air environment.

Plant-Assisted Green Synthesis of MgO Nanoparticles as a Sustainable Material for Bone Regeneration: Spectroscopic Properties.

This work is devoted to magnesium oxide (MgO) nanoparticles (NPs) for their use as additives for bone implants. Extracts from four different widely used plants, including Aloe vera, Echeveria elegans, Sansevieria trifasciata, and Sedum morganianum, were evaluated for their ability to facilitate the "green synthesis" of MgO nanoparticles. The thermal stability and decomposition behavior of the MgONPs were analyzed by thermogravimetric analysis (TGA). Structure characterization was performed by X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDS), ultraviolet-visible spectroscopy (UV-Vis), dynamic light scattering (DLS), and Raman scattering spectroscopy (RS). Morphology was studied by scanning electron microscopy (SEM). The photocatalytic activity of MgO nanoparticles was investigated based on the degradation of methyl orange (MeO) using UV-Vis spectroscopy. Surface-enhanced Raman scattering spectroscopy (SERS) was used to monitor the adsorption of L-phenylalanine (L-Phe) on the surface of MgONPs. The calculated enhancement factor (EF) is up to 102 orders of magnitude for MgO. This is the first work showing the SERS spectra of a chemical compound immobilized on the surface of MgO nanoparticles.

A method of genetic transformation and gene editing of succulents without tissue culture.

Succulents, valued for their drought tolerance and ornamental appeal, are important in the floriculture market. However, only a handful of succulent species can be genetically transformed, making it difficult to improve these plants through genetic engineering. In this study, we adapted the recently developed cut-dip-budding (CDB) gene delivery system to transform three previously recalcitrant succulent varieties - the dicotyledonous Kalanchoe blossfeldiana and Crassula arborescens and the monocotyledonous Sansevieria trifasciata. Capitalizing on the robust ability of cut leaves to regenerate shoots, these plants were successfully transformed by directly infecting cut leaf segments with the Agrobacterium rhizogenes strain K599. The transformation efficiencies were approximately 74%, 5% and 3.9%-7.8%, respectively, for K. blossfeldiana and C. arborescens and S. trifasciata. Using this modified CDB method to deliver the CRISPR/Cas9 construct, gene editing efficiency in K. blossfeldiana at the PDS locus was approximately 70%. Our findings suggest that succulents with shoot regeneration ability from cut leaves can be genetically transformed using the CDB method, thus opening up an avenue for genetic engineering of these plants.

Dissolving Pulp from Sansevieria Trifasciata Fiber Processed with Water-Pre-Hydrolysis, Soda-Anthraquinone Cooking and Clorine Free Bleaching<i> </i>

For a long time, rayon has been produced using dissolving pulp (DP). DP is typically made from wood or cotton, but it takes a long time to collect wood, and high-quality cotton must be imported from afar. Sansevieria trifasciata (ST) fiber, which contains more than 50% cellulose, offers potential as a raw material and a substitute for cotton and wood. It is simple to develop and grow. It can endure a wide range of light and temperature conditions. By using the water-pre-hydrolysis, soda-Anthraquinone cooking (soda-AQ), and elementary-chlorine-free (ECF) bleaching sequences, this work aims to convert ST into DP. Results, The DP was produced with a yield of 43.69%, a kappa value of 4.73, a viscosity of 9.3 cP, an alpha-cellulose content of 97.7% and a brightness of 90.7%, which was higher than the ISO brightness of 88%. The DP quality corresponds to the minimum DP level for rayon according to the Indonesian National Standard (SNI). It is very promising for further development, such as being used for viscose fiber production.

Development of sansevieria trifasciata/natural rubber composites for a soft body armor application

Body armor is an indispensable material in the military and defense. The development of body armor nowadays has shifted to lower-cost material with comparable ballistic properties. This research studied the potential of sansevieria trifasciata (ST) fiber as a reinforcement in soft body armor composite. The ST fiber was treated with various NaOH concentrations to achieve the highest tensile strength. The result showed that the highest ST fiber strength was achieved at 1.2GPa by treating the fiber with 1 wt% NaOH solution. The rebound resilience properties of the natural rubber (NR) matrix were optimized by varying the accelerator and carbon black content and were tested according to ISO 4662. The optimum energy absorption of the NR matrix was obtained using 0.4 part per hundred rubber (phr) accelerator and 30 phr carbon black. The ballistic performance of ST/NR composites was evaluated through a simulation using LS-DYNA software. The ballistic simulation revealed that the minimum thickness of ST/NR composite was 15mm to stop a bullet with a velocity of 436m/s. The results of this study indicated that ST/NR green composite was a promising candidate for a soft body armor application.

GC-MS validated phytochemical up-leveling with in vitro-raised Sansevieria trifasciata [Prain]: The Mother in Law’s tongue gets more antibacterial

Antimicrobial resistance (AMR) poses a critical global health challenge, jeopardizing the efficacy of infectious disease treatments and necessitating innovative solutions. The exploration of plants, renowned for their wealth of bioactive compounds, as sustainable sources of antimicrobials is gaining momentum. Sansevieria, a succulent plant genus, boasts ornamental, medicinal, and pollution-remediating attributes owing to its phytochemical richness. Notably, specific species exhibit inherent antimicrobial properties, positioning them as promising reservoirs of alternative antimicrobial agents. Efficient cultivation methods are imperative for the economically viable production of Sansevierias with potential medicinal benefits. In addressing this need, in vitro micropropagation emerges as a strategic solution, enabling mass multiplication and germplasm conservation. Leveraging our previous success in achieving efficient in vitro regeneration of Sansevieria trifasciata through elevated temperatures and auxin supplementation, we present a novel PTC-assisted antimicrobial elicitation platform. This innovative approach resulted in significantly augmented biomass production, heightened concentrations of potent phytochemicals, and increased antibacterial activity in tissue extracts compared to their field-grown counterparts. Gas chromatography-mass spectrometry (GCMS) profiling confirmed the upregulation of phytochemicals known for their antibacterial efficacy. Notably, Citronellol, 7,8-Epoxylanostan-11-ol, 3-acetoxy, and several new compounds were markedly elevated in PTC-raised Sansevieria trifasciata. Our study furnishes compelling evidence for the efficacy of in vitro techniques in enhancing the growth and phytochemical profiles of Sansevieria plants. This opens new avenues for their commercial production, particularly in addressing the challenges posed by antimicrobial resistance. Importantly, this study represents the first exploration of phytochemical bioprospecting in the Sansevieria genus through in vitro tissue culture endeavors.

Mechanical characterization of randomly oriented short Sansevieria Trifasciata natural fibre composites

Abstract The present work investigates the mechanical characteristics of randomly oriented short Sansevieria Trifasciata Fibre Polyester (STFP) composites. The STFP composites are fabricated using compression moulding methods with varying fibre weight percentages (5 %–50 %) and fibre lengths (5 mm–50 mm). It has been observed that the impact, flexural, and tensile strength of STFPs improve as the length of the fibre increases, up to a maximum of 40 mm. After that, these properties start to decrease as the length of the fibre further increases. Further, the analysis revealed that STFPs exhibited an increase in properties when the fibre weight percentage was less than 40 %, followed by a decrease in properties as the fibre percentage increased beyond that point. The impact strength of STFP is around 8.2 J/cm2. Similarly, the STFP has a flexural modulus and strength of about 3.4 GPa and 82.6 MPa, respectively. Lastly, the tensile strength of STFP is around 78.26 MPa, the elongation at break is between 6.25 % and 9.36 %, and the Young’s modulus is 11.8 GPa. The matrix and fibre interaction were examined by Scanning Electron Microscopy (SEM). Furthermore, Thermogravimetric (TGA) and Differential Scanning Calorimeter (DSC) analyses are carried out. From these analyses, the thermal stability of STFP is 200 °C and its activation energy is 65.48 kJ/mol. After a thorough comparison with other well-known natural fibres, the proposed properties of STFP demonstrate its superiority as a practical and effective natural fibre composite.

Sansevieria trifasciata biomass-derived activated carbon by supercritical-CO2 route: Electrochemical detection towards carcinogenic organic pollutant and energy storage application

Activated carbon (AC) has been widely used for electrochemical applications, such as electrochemical sensors, energy storage applications, etc., due to its fine porous structure, volumetric capacitance, and chemical stability. Supercritical-CO2 (SC-CO2) has a fascinating advantage in material science due to its microbubble cavitation, high diffusivity, and high permeability. In the shed of light, we developed a high porous Sansevieria trifasciata biomass-derived AC by SC-CO2 (SC-ST-AC). For comparison purposes, the AC was also prepared in a conventional approach (C-ST-AC). The prepared ACs were characterized through various spectroscopic and microscopic techniques to study their surface morphological character, structural analysis, and phase purity. The electrochemical performance was evaluated by two different applications: electrochemical detection and energy storage application. Based on the results, the SC-ST-AC exhibits higher porous architecture in their morphology and high phase purity with amorphous nature than C-ST-AC. In the preliminary electrochemical analysis, SC-ST-AC achieved higher performance than C-ST-AC. Thus, SC-ST-AC is applied to the real-time application and it exposed a superior limit of detection (0.005 μM L−1) and sensitivity (0.854 μA μM−1 cm−2) towards MA sensing and higher specific capacitance (342.5 F/g for 2 A/g) with 92.09 % of retention at high current density. Thereby, we suggest the SC-CO2 method is a promising approach to develop a highly porous carbon material with excellent electrochemical performance.

Manufacturing of high brightness dissolving pulp from sansevieria-trifasciata fiber by effective sequences processes

The need of dissolving pulp (DP) for rayon fiber production is increasing rapidly in recent years. Sustainable sources of DP raw materials and an effective manufacturing process are urgently required. This study aims to manufacture dissolving pulp (DP) with high brightness from Sansevieria-trifasciata (ST) fiber through the pre-hydrolysis, soda-Anthraquinone (Soda-AQ) cooking, and chlorine-free bleaching processes. The cellulose content, kappa number, pulp yield, and viscosity were analyzed. The results showed that the ?-cellulose content in ST raw material (39.43%) was relatively similar to the ?-cellulose content in Acacia pulping kraft (39.2%). Furthermore, the variations in pre-hydrolysis time affected the Kappa number, pulp yield, and viscosity. The DP obtained by the elementary chlorine-free (ECF) bleaching process had a viscosity of 9.3 cP, ?-cellulose content of 97.7%, and the brightness of 90.1% which was higher than the ISO standard of pulp brightness. The high DP brightness obtained from this unique combination of pre-hydrolysis, soda-AQ cooking and chlorine-free bleaching sequences has great potential for further development, as it can be used in viscose rayon staple fibers production.

Isolation and Properties of Cellulose Nanocrystals Fabricated by Ammonium Persulfate Oxidation from Sansevieria trifasciata Fibers

Cellulose nanocrystals (CNCs) were successfully prepared from Sansevieria trifasciata fibers (STFs) via ammonium persulfate (APS) oxidation in this study. The influences of the APS concentration (1.1, 1.5, and 1.9 M) and oxidation temperature (60, 70, and 80 °C) on the characteristics of CNCs were studied. The resulting CNCs were characterized using Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), and thermogravimetric analysis (TGA). The TEM observations revealed that the rod-like CNCs possessed average length and diameter ranges of 96 to 211 nm and 5 to 13 nm, respectively, which led to an aspect ratio range of 16–19. The optimum conditions for maximum crystallinity were achieved at an oxidation temperature of 70 °C, a reaction time of 16 h, and an APS concentration of 1.5 M. All CNCs exhibited lower thermal stability compared to the STFs. The CNCs could be produced from the STFs through the APS oxidation process and showed potential as nanocomposite reinforcement materials.
