background & aim: the world production and consumption of essential oils and perfumes are increasing very fast. lippia citriodora h.b.k. is an herbal species mainly used as a spice and medicinal plant. endogenous levels as well exogenous application of plant growth regulators (pgr) could affect essential oil production and chemical compositions. experimental: to study the effect of exogenou...

nowadays, tobacco is considered as one of the important world industrial plants. in the present study, for a creation of somaclonal variation, calli were produced on ms medium supplemented by 2 mg/l of naphthalene acetic acid (naa) and then regenerated on ms medium supplemented with 1 mg/l benzyl amino purine (bap) and 0.1 mg/l of naa. to determine correlations among traits and to fit multiple ...

amino acid dehydrogenases (l-amino acid: oxidoreductase deaminating ec 1.4.1.x) are members of the wider superfamily of oxidoreductases that catalyze the reversible oxidative deamination of an amino acid to its keto acid and ammonia with the concomitant reduction of either nad+, nadp+ or fad. these enzymes have been received much attention as biocatalysts for use in biosensors or diagnostic kit...

BACKGROUND Acetic acid bacteria (AAB) are widely applied in food, bioengineering and medicine fields. However, the acid stress at low pH conditions limits acetic acid fermentation efficiency and high concentration of vinegar production with AAB. Therefore, how to enhance resistance ability of the AAB remains as the major challenge. Amino acids play an important role in cell growth and cell surv...

Acid-soluble collagen could be isolated from fish skin using acetic acid. In recent years, much attention has been paid to collagen from marine sources, mainly arising from the fact that there is no risk of contagious diseases. Moreover, by processing the fish, significant amounts of waste materials are produced which can be considered as a substitute for these collagen sources. Thunnus tonggol...

In vitro propagation of AZ x M9 new apple rootstock resulted of breeding program of vegetative apple rootstock in Iran was investigated. Nodal explants were inoculated in Murashige and SKoog (MS) medium supplemented with various concentrations of 6-benzylaminon purine (BAP) (0.4, 0.8 and 1.2 mg/l) alone or with naphthalene acetic acid (NAA) (0.1 mg/l). We examined the effect of differe...

In vitro clonal propagation of Ashoka, Saraca asoca (Roxb.) De Wilde plant was achieved using shoot tip, nodal and internodal explants. The explants were cultured on MS medium supplemented with different concentrations (0.5-2.0mg/l) of Benzyl amino purine (BAP), Kinetin (Kn) and 2, 4-Dichlorophenoxy acetic acid (2,4-D). The synergetic effect of BAP (0.5mg/ l) induced a mean of 11.71±0.53 advent...

In vitro production of camptothecin (CPT) was achieved by the establishment of multiple shoot and root cultures of Ophiorrhiza rugosa Wall. var. decumbens (Gardn. ex Thw.) Deb & Mondal. The maximum multiple shoots were obtained in Murashige and Skoog (MS) medium supplemented with 5mg/l N-benzyl amino purine (BA) along with 0.5mg/l naphthalene acetic acid (NAA). Optimal root generation was obser...

In vitro callus induction and shoot emergence protocols for Maytenus emarginata (Willd) Ding Hou. have been established using young leaves stem explants of in vivo growing, one half year-old plants. Plants were growing the month August 2016 at department Botany, Ch. Charan Singh University, Meerut. However, collected August, 2019. MS (Murashige Skoog) medium WPM (Woody Plant Medium), supplement...
