Wheat is the main staple food in world, so it backbone of security. Drought not only affects growth and development but also ultimately has a severe impact on overall productivity crop plants. Some bacteria are capable producing exopolysaccharides (EPS) as survival mechanism, along with other metabolites, which help them survive stressful conditions. The present study was conducted aim inducing...

Effect of salts (Na2SO4, Na2CO3, MgSO4, NaCl, MgCl2), soil extract and polyethylene glycol (PEG-6000) on the germination of Chenopodium glaucum L., seed was studied. Maximum germination was obtained in distilled water. Germination decreased with increase in salinity. The inhibition of germination by salt solutions was in the order of MgCl2 > Na2SO4 > Na2CO3 > NaCl > Soil extract > MgSO4. Germin...

We investigated the role that manganese superoxide dismutase (MnSOD), an important antioxidant enzyme, may play in the drought tolerance of rice. MnSOD from pea (Pisum sativum) under the control of an oxidative stress-inducible SWPA2 promoter was introduced into chloroplasts of rice (Oryza sativa) by Agrobacterium-mediated transformation to develop drought-tolerant rice plants. Functional expre...

The present work investigates the feasibility of the design of an enteric coated microporous osmotic pump tablet (ECMOPT) to prolong the drug release of an antipsychotic drug, quetiapine fumarate (QTF). The ECMOPT consisted of an osmotic core coated with a microporous membrane (MPM) made up of cellulose acetate and PEG 4000 as in situ micropore former. The effect of formulation variables such a...

Osmotic and oxidative stress responses to iso-osmotic (-0.4 Mpa) NaCl, PEG-6000 and mannitol stress were studied in 15-day old plants of three potato cultivars viz. ‘Kufri Kufri Bahar’ ‘Jyoti’ and ‘Chandramukhi’. After 2-weeks of treatment, plants were analyzed for biochemical and physiological determinants of stress. Relative water content (RWC) and membrane damage rate (MDR) were significantl...

Papain was purified from spray-dried Carica papaya latex using aqueous two-phase system (ATPS). Then it was recovered from PEG phase by in situ immobilization or preparing cross-linked enzyme aggregates (CLEAs). The Plackett-Burman design and the central composite design (CCD) together with the response surface methodology (RSM) were used to optimize the APTS processes. The highly purified papa...

Abstrak PEG sering dipergunakan untuk seleksi toleransi cekaman kekeringan pada fase perkecambahan benih. Selain itu juga dapat berguna osmoticum priming karena bersifat inert secara kimiawi dan tidak menimbulkan efek merusak embrio Penelitian ini bertujuan mengetahui konsentrasi kritis pemberian poly ethylene glycol (PEG 6000) yang menyebabkan penurunan benih 3 varietas cabai local Sumatera Ba...

Phase diagrams and the compositions of coexisting phases of poly(ethylene glycol) (PEG) 6000 + sodium succinate + water system have been determined experimentally at 298.15, 308.15, and 318.15 K. The effects of temperature on the binodal curve and tie lines have been studied. The binodal curves were successfully fitted to a nonlinear equation relating the concentrations of PEG 6000 and sodium s...
