Abstract

Culturing the individual plant cells, tissues (explants) and organs in laboratory or in vitro on synthetic media (MS media) under aseptic conditions is a usual process in plant tissue culture studies. The medium is rich in nutrients, also supports the growth of variety of microorganisms especially bacteria and fungi, which causecontamination of the medium, though the media is sterilized by autoclaving. During the process of cooling and transferring the media, the chances of fungal contamination remain high. This is avoided to the maximum extent following the good laboratory practices. A novel means could be incorporating turmeric, a well -known antifungal agent, into the media. In the present study, attempts were made to avoid fungal contamination using the media with various concentration of turmeric powder. Results of the investigation revealed that turmeric powder used at the concentrations of 0.8 g/L and 1.0 g/L in the media resulted in appreciable control of fungal contamination.

Abstract:
Culturing the individual plant cells, tissues (explants) and organs in laboratory or in vitro on synthetic media
(MS media) under aseptic conditions is a usual process in plant tissue culture studies. The medium is rich in
nutrients, also supports the growth of variety of microorganisms especially bacteria and fungi, which cause
contamination of the medium, though the media is sterilized by autoclaving. During the process of cooling and
transferring the media, the chances of fungal contamination remain high. This is avoided to the maximum extent
following the good laboratory practices. A novel means could be incorporating turmeric, a well -known anti-
fungal agent, into the media. In the present study, attempts were made to avoid fungal contamination using the
media with various concentration of turmeric powder. Results of the investigation revealed that turmeric powder
used at the concentrations of 0.8 g/L and 1.0 g/L in the media resulted in appreciable control of fungal
contamination.
Key words: Turmeric, Sesamum orientale, Sesamum indicum, Curcumin.
Introduction
Prevention or control of contamination in in-vitro plant culture has been strictly based on the use of sterile
techniques. Any subsequent manipulation of the plant tissue must typically be carried out in a filtered-air
environment, e.g., in a laminar-flow hood (Bottino, 1981). Endophytic or latent type contamination by bacteria
and fungi (Kneifel and Leonhardt, 1992; Ryu and Holt, 1993) is an insidious process that continually threatens
plant tissue culture techniques throughout the duration of the culture period. Chemical anti-microbial agents
(Gilbert, 1991) such as benzyl pencillin, phosphomycin, chloremphenicol, rifamphicin (Haldeman et al., 1987;
Phillips et al., 1981), nalidixic acid, etc., have been used in different crops (Chapman, 1994; Dodds, J. H., and L.
W. Roberts. 1985) to avoid the contamination. These chemical antimicrobial agents generally trigger the normal
physiological and chemical functions of the plant.
Using the environmental friendly materials to check the microbial activity is a beneficiary process,
which reduces the cost as well as the inefficiency. Turmeric (Curcuma longa) is one such compound, which was

used in traditional medicines as an anti-inflammatory (N. Niamsa and C. Sittiwet; 2009). It was also used in
wide range of conditions including respiratory diseases, liver disorders, sprains and sinusitis. It also has healing
property and ability to help the body to fight off microbes. The turmeric has shown its effect on some of the
diseases viz., antifungal, antimicrobial, antispasmodic, anti-inflammatory, Anti-venom, appetite stimulant,
asthma, bleeding, bloating, boils, bruises, cataracts, colic, contraception, cough, cystic fibrosis, diabetes,
diarrhea, dizziness, epilepsy, gas, gonorrhea, heart damage from Doxorubicin, helicobacter pylori infection,
hepatitis, hepatoprotection, high blood pressure, human papillomavirus (HPV), infections (methycillin-resistant
Staphylococcus aureus) (Kulkarni RR, Patki PS, Jog VP, et al. (1991), insect bites, insect repellent, jaundice,
kidney disease, lactation stimulant, leprosy, liver protection, male fertility, menstrual pain, menstrual period
problems/lack of menstrual period, liver damage from toxins/drugs, multidrug resistance, neurodegenerative
disorders, pain, parasites, ringworm, scarring, scleroderma. Mainly these wide variety of applications were
concentrated on the animal related problems/diseases, while on plant related aspects the applications of turmeric
was meager.
For the first time an attempt has been made to use turmeric in culture media to prevent and control
endophytic and latent contamination (Gilbert et al., 1991; Green, 1993; Haack and Warwick, 1993). The main
aim of the investigation is to test the turmeric as an antimicrobial agent in preventing and controlling the
endophytic and latent contamination in the culture media of sesame. To know at which concentration turmeric
functions effectively as an antibiotic in the plant tissue culture media, and also to know the residual effects of
turmeric on plant tissue of sesame.

Various concentrations of turmeric were used along with MS media under similar environmental
conditions. The percentage of contamination observed is represented in table 4 and figure 1. MS media with 0.8
g/L and 1.0 g/L of turmeric and 2.0 g/L of carbendazium has recorded nil contamination, while highest
contamination was recorded using MS media with K. cyclin (0.5 and 1.0 g/L concentration) and MS media
alone (Figure 2). The contamination was observed even with the turmeric at minimum concentration of 0.6g/L
and at high concentration 2.0 g/L (Figure 3). Hence, it can be depicted that a moderate amount of turmeric
between 0.8 – 1.0 g/L of turmeric can nullify the contamination in tissue culture studies (Figure 4). MS media
with carbendazium has also showed the null contamination at 2.0 g/L. Further the carbendazium is a chemical
compound, which can be hazardous, while the turmeric plays an important role as an effective
antifungal/microbial agent.

Early Prediction of Type- II Diabetes Mellitus in Young Adults using LSTM
Conference Paper
  • Jun 2024
Diabetes Mellitus Type II (T2DM) is a major global health concern, with a growing prevalence among young adults. Early detection of T2DM is imperative for mitigating long-term complications and the conventional diagnostic methods often lag in the prediction of T2DM leading to T2DM progression. Therefore, it is necessary for advanced techniques in early and non-invasive prediction to be implemented for early prediction of T2DM. Leveraging Long Short-Term Memory (LSTM) networks, this research explores the efficacy of deep learning in T2DM prognosis among young adults. For this objective, real-world datasets from young adult populations were employed for evaluation, demonstrating compelling results with a training accuracy of 1.0 and 0.98 for the testing dataset. The results displayed significant potential of LSTM networks in the early T2DM detection. Present work adds to the growing database of research related to the application of deep learning for decisive disease detection with opportunities for better investigation into the integration of various biomarkers and deep learning architectures. Lastly, the study focused on the incorporation of clinical decision support systems and assists in the process of empowering healthcare practitioners with actionable insights for personalized interventions in young adults at risk of T2DM.

  • Jan 2022
Inorganic fertilizers have impacts on the availability of nutrients and the content of organic matter in the soil, as well as on its native microbiota. A turmeric fertilizer (TF) with added food residues and wood ashes was developed to evaluate its effects on tomato production and crop soil properties. The TF was prepared by emulsion technology using three turmeric concentrations expressed as 1.0, 2.5 and 3.0 % w/v; it was characterized according to its rheological (apparent viscosity, consistency and flow behavior indexes) and physical (z-average droplet size) characteristics. Nitrogen, phosphorus and potassium (NPK) levels and moisture-holding capacity were measured in crop soil. Colour, soluble solid content, acidity, diameter and the number of tomatoes were evaluated. The photosynthetic index of the leaves of tomato plants was determined. It was observed that when turmeric concentration increased (> 1.0 % w/v), the droplet size decreased enhancing the physical stability of TF. NPK levels and moisture-holding capacity of the soil improved, especially with turmeric concentrations > 1.0% w/v. Positive effects on the tomato fruit properties (soluble solid content, acidity, diameter and tomato number) and photosynthetic index of tomato plant leaves were observed with turmeric concentrations of 2.5 and 3.0 % w/v. The TF positively influenced the crop soil and the metabolic process of the tomato plants, and the characteristics of its fruits.

Several compounds (cinnamon oil, cinnamaldehyde, clove oil, eugenol, and potassium sorbate) were assayed to evaluate their potential as inhibitors of Penicillium expansum growth on apples and in apple juice. The effectiveness of inhibitor was dependent on the apple cultivar treated. Both 0.1% cinnamon oil and 0.5% potassium sorbate decreased spoilage as measured by lesion diameter in most of the cultivars studied. Patulin was not detected in apple juice containing 0.3% cinnamon oil or 0.5% sorbate after incubation with P. expansum for 7 d at 25 degrees C. The addition of benomyl (0.5-5 ppm) increased patulin production by P. expansum grown in apple juice. These results indicate that surface application of cinnamon oil or potassium sorbate might be an effective postharvest treatment for apples, and addition of these compounds to apple juice products that do not receive additional heat treatment, such as 'fresh' apple cider, would prevent patulin production by P. expansum.

The use of antibiotics to eliminate latent bacterial contamination in potato tissue cultures
Article
SummaryA simple leaf bioassay was developed to screen for slow-growing latent bacteria found in potato nodal cuttings. The potato cultures were established to provide a source of sterile leaf tissue for protoplast isolation and the bacteria were only detected after numerous generations in culture. In an attempt to solve this problem cultures were screened before and after various treatments. Two antibiotic mixtures were tested for their efficacy in eliminating bacteria: ABM1 contained penicillin, streptomycin, amphotericin and NaCl while ABM2 contained erythromycin, streptomycin and carbenicillin at various concentrations. Both cocktails, when added to the micropropagation medium, reduced plant growth, induced chlorosis at higher levels and did not eliminate contamination. In terms of protoplast isolation, the only effective treatment was when ABM1 was incorporated into the plasmolysis and enzyme media. It removed contamination at all levels tested and had a differential effect on cell division such that, at low levels of ABM1, protoplasts regenerated successfully.

Testing of different antibiotics against Gram-positive and Gram-negative bacteria isolated from plant tissue culture
Article
  • May 1992
Different Gram-positive and Gram-negative bacteria (Staphylococcus xylosus, S. aureus, S. cohnii, Bacillus sp., Corynebacterium sp., Pseudomonas vesicularis) were isolated from homogenized shoot tips of Drosera rotundifolia, Spatiphyllum sp., Syngonium cv. White butterfly, Nephrolepis exaltata cv. Teddy Junior. Growth inhibition of selected bacterial strains was examined using 28 different single antibiotics and 7 antibiotic mixtures. It was found that with the two mixtures Imipenem/Ampicillin and Imipenem/Penicillin G at concentrations of 5 mg l–1 each, bacterial growth inhibition was most effective. Because of the lack of toxic effects on in vitro plants of 7 species it was proposed that these antibiotic mixtures can be applied advantageously to inhibit bacterial growth in tissue culture.

Treatment of osteoarthritis with a herbomineral formulation: a double-blind, placebo-controlled, cross-over study
Article
  • May 1991
  • J ETHNOPHARMACOL
The clinical efficacy of a herbomineral formulation containing roots of Withania somnifera, the stem of Boswellia serrata, rhizomes of Curcuma longa and a zinc complex (Articulin-F), was evaluated in a randomized, double-blind, placebo controlled, cross-over study in patients with osteoarthritis. After a one-month single blind run-in period, 42 patients with osteoarthritis were randomly allocated to receive either a drug treatment or a matching placebo for a period of three months. After a 15-day wash-out period the patients were transferred to the other treatment for a further period of three months. Clinical efficacy was evaluated every fortnight on the basis of severity of pain, morning stiffness, Ritchie articular index, joint score, disability score and grip strength. Other parameters like erythrocyte sedimentation rate and radiological examination were carried out on a monthly basis. Treatment with the herbomineral formulation produced a significant drop in severity of pain (P less than 0.001) and disability score (P less than 0.05). Radiological assessment, however, did not show any significant changes in both the groups. Side effects observed with this formulation did not necessitate withdrawal of treatment.
