This study examined the effectiveness of decontamination of industrial cyanide-containing water using mycelium-based lignocellulosic materials. These results suggest that fungi biomass and plant substrates can be used successfully in the treatment of wastewater contaminated by cyanide. Fungi were isolated from old wood samples taken from a tailing dam with high cyanide content (more than 20 years in semi-submerged condition). All isolated fungi belonged to the genus Fusarium. Fusarium oxysporum Schltdl. is most effective for biodegradation of cyanide-containing wastewaters (even at low temperatures). The most optimal lignocellulosic composition for production of mycelium-based biomaterial for biodegradation of cyanide wastewater consists of a uniform ratio of Siberian pine sawdust and wheat straw. The high efficiency of mycelium-based materials has been experimentally proven in vitro at 15-25 ° C. New fungal biomaterials are provide decrease in the concentration of cyanide ions to 79% (P <0.001). Large-scale cultivation of fungi biomass was carried out by the periodic liquid-phase cultivation. The submerged biomass from bioreactor was used as an inoculum for the production of mycelium-based materials for bioremediation of cyanide wastewater in situ (gold mine tailing).

An efficient in vitro micropropagation protocol has been developed using nodal explants of ramie (Boehmeria nivea), with maximum shoots (42) per explant in 5 passages (passage duration: 21 days) on Murashige and Skoog medium supplemented with 2.0 mg/l 6-benzyladenine and 2.0 mg/l AgNO<sub>3</sub>. ½ Murashige and Skoog medium containing 40% sucrose was found to be most effective for the rooting of in vitro developed shoots. Those plantlets were acclimatized and transferred to pots for hardening under glasshouse conditions. About 91% of mericlones survived and showed no ectopic expression in respect of any morphological character in comparison with the parental stock. Furthermore, clonal fidelity of the mericlones was confirmed by using DNA markers (random amplified polymorphic DNA and inter simple sequence repeats) and by polypeptide profiling through SDS-PAGE at a genomic and protein level, respectively, which showed the true-to-type nature of the in vitro micropropagated plants. Thus the protocol developed can be used to generate safe planting material for large-scale cultivation of ramie.

Abstract In the past few decades, major initiatives have been launched around the world to address chemical safety testing. These efforts aim to innovate and improve the efficacy of existing methods with the long-term goal of developing new risk assessment paradigms. The transcriptomic and toxicological profiling of mammalian cells has resulted in the creation of multiple toxicogenomic datasets and corresponding tools for analysis. To enable easy access and analysis of these valuable toxicogenomic data, we have developed ToxicoDB (toxicodb.ca), a free and open cloud-based platform integrating data from large in vitro toxicogenomic studies, including gene expression profiles of primary human and rat hepatocytes treated with 231 potential toxicants. To efficiently mine these complex toxicogenomic data, ToxicoDB provides users with harmonized chemical annotations, time- and dose-dependent plots of compounds across datasets, as well as the toxicity-related pathway analysis. The data in ToxicoDB have been generated using our open-source R package, ToxicoGx (github.com/bhklab/ToxicoGx). Altogether, ToxicoDB provides a streamlined process for mining highly organized, curated, and accessible toxicogenomic data that can be ultimately applied to preclinical toxicity studies and further our understanding of adverse outcomes.

Recently, microalgae cultivation for different applications, including the production of nutritional and pharmaceutical active compounds has received increasing attention. Among the different genera, Spirulina (Arthrospira sp.) is one of the most promising blue-green microalgae (Cyanophyta) because it is rich in antioxidants, essential amino acids (EAAs), minerals, proteins, polyunsaturated fatty acids and vitamins. It has a high protein content (60-70% of the dry weight), which is a complete protein, i.e. containing all EAAs. Therefore, Spirulina is currently a commercial product with high nutritional value and also a significant source of complementary and alternative medicine. The objective of the present work was to review the pharmaceutical and therapeutic applications of Spirulina, especially its antioxidant, anti-inflammatory, anti-cancer, anti-microbial, anti-diabetic, anti-obesity and anti-toxicity properties. The results were obtained from experiments in the literature performed in vitro and in vivo using experimental animals. The main reported active ingredients in Spirulina include phycocyanin, tocopherol, β-carotene, caffeic acids and chlorogenic acid, which showed individual or synergetic effects. In addition, the present review discusses the future perspectives of genetically modified Spirulina as a source for industrial products while producing valuable biomass photoautotrophically. Furthermore, the consequent environmental impacts of large-scale cultivation of Spirulina are discussed.

Curcuma longa (C. longa) is widely known for its medicinal properties. However, the potential overexploitation of this plant raises doubts about its long-term survival on Rapa Nui. Micropropagation using a temporary immersion system (TIS) could be the basis for developing a cost-effective and highly productive method of large-scale cultivation of this plant. Our objective was to develop and refine the in vitro multiplication system for mass propagation of C. longa, and thus help restore the fragile ecosystem of Rapa Nui. Three parameters were evaluated: number of explants per flask, flask capacity, and LEDs spectrum. For each parameter evaluated, four aspects were analyzed: fresh weight per plant, number of shoots, percentage of non-sprouting explants, and the proliferation rate. The use of 30 explants per two-liter flask results in more plants with high fresh biomass than other configurations. In addition, LEDs with a red:blue ratio of 2:1 provided the best lighting conditions for in vitro propagation and positively affected C. longa proliferation and rooting. Therefore, our results show that 30 explants per two-liter flask and an LED source with a red:blue ratio of 2:1 allow a higher number of C. longa plants to be obtained using TIS.

AbstractMetabolic profiling of cell line collections have become an invaluable tool to study disease etiology, drug modes of action and personalized medicine. However, large-scalein vitrodynamic metabolic profiling is limited by time-consuming sampling and complex measurement procedures. By adapting an MS-based metabolomics workflow for high-throughput profiling of diverse adherent mammalian cells, we establish a technique for the rapid measurement and analysis of drug-induced dynamic changes in intracellular metabolites. This methodology is scalable to large compound libraries and is here applied to study the mechanism underlying the toxic effect of dichloroacetate in ovarian cancer cell lines. System-level analysis of the metabolic responses revealed a key and unexpected role of CoA imbalance in dichloroacetate toxicity. The herein proposed strategy for large-scale drug metabolic profiling is complementary to other molecular profiling techniques, opening new scientific and drug-discovery opportunities.

An efficient protocol for micropropagation through in vitro culture of Rauvolfia serpentina was standardized. Out of different combination of phytohormone tested, MS media supplemented with 0.5 mg L-1Indole Acetic Acid + 0.5 mg L Nephthalene acetic acid was found to be finest for mean callus induction (62.66%) as well as callus mediated shoot regeneration with mean percentage response (56) and number of shoot per culture (5). In direct shoot regeneration, best growth of axillary shoots was obtained on MS media supplemented with 0.5 mg L-1 Indole Acetic Acid + 0.5 mg L-1 Benzyl Amino Purine with maximum mean percentage response(77.33) and number of shoots per culture (9.0) ,however the best shoot elongation of shoot was found on MS media supplemented with 3.0 mg L-1 IAA plus 3.0 mg L-1BAP with 6.50(mean) . Higher induction of root (88%) with mean number of root per culture (12) was observed in MS medium supplemented with Indole Butyric Acid (3.0 mg L-1). The rooted plantlets were successfully established in the field. The protocol was optimized by manipulations of different PGRs for enhanced multiplication. Protocol explained in this research paper provides a rapid plant regeneration system which could be used for production of large number of true to the type, uniform, disease free, elite, plantlets right through the year, which will make things easier for large scale cultivation of this endangered important medicinal plant.
