Newest firstRoots are major contributors to nutrient acquisition, water absorption, and plant anchoring and stability. However, little is known about the root system of industrial hemp (Cannabis sativa L.), an increasingly important crop worth $16 billion annually. Hemp is commonly cultivated for grain as an oilseed, stalk biomass for fiber and industrial materials, but has also had growing interest for its carbon sequestrati…
Open article record in new tab ↗Hemp (Cannabis sativa L.) is increasingly valued not only for its fibers and seeds but also for essential oils derived from floral by-products. This study investigates the extraction of essential oils from three hemp floral varieties, Sour Space Candy, Suver Haze 3N, and Pinewalker 3N using hydrodistillation, a widely accepted and efficient method for isolating volatile compounds. The chemical composition and quan…
Herbaceous plant biomass is an important resource for energy production and an effective strategy to ensure energy supply independence. Growing agricultural plant mixtures (multicrops) contributes to increasing biomass yields, enhancing farm biodiversity, improving soil health, and promoting environmental sustainability. However, most crop mixtures have not been studied at all. For this reason, stationary field ex…
As wood is still scarce in some countries, it is necessary to replace wood in the paper industry with other lignocellulosic raw materials, particularly agricultural residues. This study evaluated hemp, flax, and sisal postharvest biomass as alternative nonwoody fibrous feedstocks for pulp and paper production. Pulping was performed using soda and nitrate-alkaline methods under comparable degrees of delignification…
Open article record in new tab ↗Biochar application to soil has been promoted to mitigate climate change by reducing greenhouse gas (GHG) emissions, yet significant uncertainty exists in quantifying soil nitrous oxide (N2O) emissions from biochar-amended soils. We evaluated soil N2O emissions from soils amended with biochar prepared from diverse agricultural and forest biomass and underlying biogeochemical mechanisms using long-term soil incubat…
After cannabidiol was extracted from the hemp biomass using supercritical CO2 extraction, the residual could be utilized as a source of other valuable ingredients. The stability of the extracted CBD in pre- and post- encapsulation states were evaluated. Dynamic macerations with ethanol and hexane were compared for CBD extraction. The ethanol extract yielded 0.11% ± 0.10 CBD and 1.83% ± 0.00 cannabidiolic acid (CBD…
Open article record in new tab ↗The photopolymerization process in 3D printing is considered greener once it involves a fast reaction and low energy consumption. Various reactions for photopolymerization can be used nowadays, but a special one is the thiol-ene "click" reaction that occurs in equimolar concentrations of thiol and alkene groups. In this sense, solvent-free photopolymerizable formulations were prepared to contain non-modified casto…
Open article record in new tab ↗Introduction Relative humidity (RH) is critical for regulating transpiration, plant morphology, and the biosynthesis of secondary metabolites in crops. However, its specific impacts on cannabis (Cannabis sativa L.) genotypes, especially concerning optimal growth and cannabinoid concentration, remain inadequately understood.This study aimed to investigate the effects of canopy-level RH on plant development and cann…
Open article record in new tab ↗The feasibility of using a combination of organic fertilizer with a reduced rate of chemical nitrogen fertilizer as an alternative to conventional inorganic fertilization was tested on the growth and biomass accumulation of hemp plants and the phytochemical accumulation in their inflorescences. To achieve this goal, a field experiment was set up with the following nine treatments: F0, no fertilizer; NPK, mineral f…
The establishment of industrial hemp (Cannabis sativa L.) fields near row crops has raised concerns about the potential adverse effects of herbicide drift on hemp production. This study examined hemp susceptibility to drift of herbicides registered for use in corn and/or soybeans. Herbicide solutions (2,4-D, dicamba, glufosinate, glyphosate, imazethapyr, lactofen, mesotrione) were applied separately in the wind tu…
Open article record in new tab ↗The inclusion of spent hemp biomass (SHB), an extracted byproduct from industrial cannabidiol (CBD) production, in the diets of dairy cows and lambs appears to be safe with minor effects on the metabolism, including a decrease in circulating cholesterol and increase bilirubinemia, both associated with liver metabolism. Those effects could be consequence of the presence of cannabinoids, particularly Δ9-tetrahydroca…
Open article record in new tab ↗Energy storage in electrochemical hybrid capacitors involves fast faradaic reactions such as an intercalation, or redox process occurring at a solid electrode surface at an appropriate potential. Hybrid sodium-ion electrochemical capacitors bring the advantages of both the high specific power of capacitors and the high specific energy of batteries, where activated carbon serves as a critical electrode material. Th…
Open article record in new tab ↗Supercritical carbon dioxide (CO2) extraction techniques meet all-new consumer market demands for health-promoting phytochemical compound-rich extracts produced from green and sustainable technology. In this regard, this review is dedicated to discussing is the promise of integrating high-pressure CO2 technologies into the Cannabis sativa L. processing chain to valorize its valuable pharmaceutical properties and f…
Open article record in new tab ↗The breeding of hybrid cultivars of hemp (Cannabis sativa L.) is not well described, especially the segregation and inheritance of traits that are important for yield. A total of 23 families were produced from genetically diverse parents to investigate the inheritance of morphological traits and their association with biomass accumulation and cannabinoid yield. In addition, a novel classification method for canopy…
The use of agricultural by-products in the building engineering realm has led to an increase in insulation characteristics of biobased materials and a decrease in environmental impact. The understanding of cell wall structure is possible by the study of interactions of chemical compounds, themselves determined by common techniques like Van Soest (VS). In this study, a global method is investigated to characterise…
Open article record in new tab ↗Hemp (Cannabis sativa L.) synthesizes and accumulates a number of secondary metabolites such as terpenes and cannabinoids. They are mostly deposited as resin into the glandular trichomes occurring on the leaves and, to a major extent, on the flower bracts. In the last few years, hemp for production of high-value chemicals became a major commodity in the U.S. and across the world. The hypothesis was that hemp bioma…
Open article record in new tab ↗BACKGROUND: While keeping in view various aspects of energy demand, quest for the renewable energy sources is utmost. Biomass has shown great potential as green energy source with supply of approximately 14% of world total energy demand, and great source of carbon capture. It is abundant in various forms including agricultural, forestry residues, and unwanted plants (weeds). The rapid growth of weeds not only affe…
Open article record in new tab ↗Cannabis sp. and Euphorbia sp. are potential candidates as indoor culture for the extraction of their high value-added metabolites for pharmaceutical applications. Both residual lignocellulosic materials recovered after extraction are studied in the present article as single or mixed feedstocks for a closed-loop bioprocesses cascade. An alkaline process (NaOH 3%, 30 min 160°C) is performed to separate the studied…
Open article record in new tab ↗Carbon dioxide supercritical fluid extraction (CO2 SFE) is a clean and cost-effective method of extracting cannabinoids from cannabis. Using design of experiment methodologies an optimised protocol for extraction of medicinal cannabis bud material (population of mixed plants, combined THC:CBD approximately 1:1.5) was developed at a scale of one kg per extraction. Key variables investigated were CO2 flow rate, extr…
Background Recombinant protein production is universally employed as a solution to obtain the milligram to gram quantities of a given protein required for applications as diverse as structural genomics and biopharmaceutical manufacture. Yeast is a well-established recombinant host cell for these purposes. In this study we wanted to investigate whether our respiratory Saccharomyces cerevisiae strain, TM6*, could be…
