Temporary Immersion

The cultivation of medicinal plants and the production of bioactive compounds derived from them are of fundamental importance and interest, not only at the pharmacological level but also in nutraceutical and cosmetic industries and in functional foods, as well as plant protection in agriculture. In order to respond adequately to the increased demands of the global market from a quantitative and qualitative point of view and to guarantee environmental sustainability of the productions, it is necessary to resort to innovation tools, such as tissue culture in vitro technology. Nowadays, it is well known that the cultivation through the Temporary Immersion System (TIS) in a bioreactor has considerable advantages both for the in vitro mass production of the plants and for the production of secondary metabolites. The present review focuses on the application of TIS during the last two decades to produce biomass and bioactive compounds from medicinal plants. Indeed, almost one hundred papers are discussed, and they particularly focus on the effects of the culture system, vessel design and equipment, immersion time and frequency, and substrate composition for 88 medicinal species in TIS bioreactor culture.

Plant tissue culture technology is a technique for aseptic culture of plant tissues under artificial culture conditions. It can be used as a means to directly mass-produce of bioactive compounds from different culture systems such as adventitious roots (ARs), hairy root, callus, somatic embryogenesis of medicinal plants. ARs cultures show high root proliferation, biomass production and have the potential to synthesize specific bioactive compounds. ARs can be induced in vitro from various explants, such as leaves, roots, stem, petiole callus, etc. Various parameters such as auxins, nitrous oxide, and light have shown to affect the morphogenesis of ARs. Air-lift bioreactors appear to be ideal for plant cell and organ cultures. They are suitable for the ARs culture of various medicinal plants. To scale-up ARs cultures, the Balloon type bubble bioreactor (BTBB) is reported to be a suitable system for the accumulation of both biomass and bioactive compounds production in numerous various medicinal plants. BTBB provides optimum conditions for growth and bioactive compound accumulation by efficiently controlling the culture environment, foam generation, reducing shear stress, and supplying optimal oxygen. This review summarized a strategy and approach for ARs culture for the production of biomass and secondary metabolites from laboratory to industrial scales by using air-lift bioreactor culture systems.

Emerging infectious diseases have become a major global problem with public health and economic consequences. It is an urgent need to develop new anti-infective therapies. The natural diterpene carnosol exhibit a wide variety of interesting antibacterial and antiviral properties, and it is considered a theoretical inhibitor of COVID-19 Mpro. However, this compound is present in the family Lamiaceae in low quantities. To obtain carnosol in concentrations high enough to develop pharmacological studies, we evaluated the efficiency of a micropropagation protocol of Rosmarinus officinalis using a solid medium and a temporary immersion system (TIS), as well as the effect of 6-benzylaminopurine (6-BAP) and α-naphthaleneacetic acid (NAA) on the growth of shoots. Moreover, we developed and validated an analytical method to quantify carnosol using the H-point standard additions method in the high-performance liquid chromatography diode array detector (HPLC-DAD). After 30 days of culture, TIS produced the maximum number of shoots per explant (24.33 ± 1.15) on a liquid medium supplemented with 6-BAP at 5.0 mg L−1. Next, we also evaluated the effect of immersion time and frequency for TIS. After 72 days of culture, the best results were obtained with an immersion cycle of 1 min every 12 h, yielding 170.33 ± 29.40 shoots. The quantification of carnosol on the samples was performed at a flow rate of 1.2 mL min−1 using binary isocratic mobile phase system 60:40 (v/v) 10 mM formic acid (pH 3.0) (A) and acetonitrile (B) on a reverse-phase column. The content of carnosol in the in vitro cultures was around 8-fold higher than in the wild plant. The present study represents an efficient alternative method to obtain carnosol for its pre-clinical and clinical development.

bstractTo achieve Indonesian sugar self-sufficiency in2014, the national production needs to be escalatedthrough land extensification that requires a largenumbers of cane planting materials. This can be achievedby mass propagation of sugarcane through in vitroculture. Solid medium is commonly used for callusproliferation in sugarcane tissue culture. However, solidmedium is considered inefficient in terms of plantletproduction level, labour and space. The use of liquidmedium may solve the problem by allowing automationto increase plantlet production scale and uniformity.Temporary immersion system (TIS) is based on a shortperiodic immersion of explants in a liquid medium for aspecific frequency and duration. Research on in vitromass propagation of sugarcane using TIS was conductedat the Indonesian Biotechnology Research Institute forEstate Crops. Callus initiated from immature unfoldedleaves of PSJT 941 and PS 881 was cultured on liquidMS medium in TIS with different frequencies (12 and24 h) and durations (1 and 3 min) of immersion. Eachtreatment was replicated three times. The callus biomassof two elite cane varieties (PSJT 941 and PS 881)cultured in TIS for six weeks was higher (2 – 4 times fold)than that of on solid medium. The PSJT 941 varietyreached the highest calli biomass with immersion forthree min every 24 h. However, PS 881 variety reachedits highest biomass with immersion for one minute every24 h. The propagation of sugarcane using TIS culturewas proven to produce higher calli biomass up to fourfolds and to form more numbers and uniform shootscompared to the solid medium culture. The callus wassuccesfully regenerated to shoots and plantlets.AbstrakUntuk mencapai swasembada gula, perlu dilakukanpeningkatan produksi gula nasional melalui perluasanareal pertanaman tebu sehingga diperlukan bibit dalamjumlah besar.

Taiwanofungus Camphoratus

Background: Based on traditional and folk medicine, mushrooms have been developed into anti-cancer therapeutics. In this article, a brief overview is given of the most important medical mushroom species and their specific anti-cancer functions and mechanisms. Taiwanofungus camphoratus (Antrodia cinnamomea), is a medical fungus chosen  to examine  the process from ethnomedicine to developing new products for the market based on scientific, analytic, and experimental evidence. The bioactive compounds have indirect effects in cancer treatment by benefiting the immune system as well as having direct cytotoxic effects on cancer cells.Taiwanofungus camphoratus is a fungus endemic to Taiwan and one of the most popular known alternative remedies for liver cancer in Taiwan. To date, more than 150 liver cancer patients have survived using T. camphoratus. The treatment has caused tumor shrinking, as well as the disappearance of a tumor altogether in some cases. The ratio between male and female patients has been nearly equal, with ages ranging between 20-79 years. The most effective candidates are those between the ages of 40-60 years.The complex mixture of bioactive compounds in natural fruit bodies is a challenge for artificial production in vitro. Particular problems in developing T. camphoratus into therapeutics for the global market are its rarity in nature and its close dependence on an endemic tree in Taiwan. These challenges can help promote new solutions which could be utilized in the future with other medical fungiKeywords: Medicinal mushrooms, anti-cancer therapeutics, Taiwanofungus camphoratus, liver cancer.

Protease inhibitors (PIs) are deployed in the plant kingdom as storage proteins or peptides, regulators of endogenous proteases, and plant protection agents against insect pests and pathogen attack. In humans, they are identified as chemopreventive agents against a range of cancers and have potential as drug to treat an array of disease associated with aberrant activity of proteases. The present investigation reports PIs activity data from 30 medicinal plants. The screening for PIs activity was done by dot blot assay using X-ray film coated with gelatin. Among screened seed extracts, Albizia lebbeck, Raphanus sativus, Mucuna pruriens, Achyranthes aspera, and Coffea arabica showed high inhibitory activities with trypsin protease. Most of seed extracts exhibited moderate activity, whereas Ocimum sanctum showed moderate to low activity against trypsin. The presence of varied protein content is reported from all seed extracts with highest in A. lebbeck (50.0 ± 3.4 mg/ml). The data produced in the present investigation could be helpful for further exploration of PIs as therapeutic agent.
