A synergistic microbicidal composition comprising: (a) 4,4-dimethyloxazolidine; and (b) pine oil.

Microbicidal composition

A water sampling device has a rigid body, a top lid, extension members, a horizontal member, a spring, a rod, at least one polymer membrane and a bottom lid. The top lid has a shaft attached to it and the shaft traverses through the horizontal member. The bottom lid is connected to the rod upon which the at least one polymer membrane is attached perpendicularly. The water sampling device undergoes two different stages of lid opening and closing while in operation of collecting water sample to concentrate diversified bacteria from different water depths. The top lid, the shaft and the spring co-operate with the rigid body and the horizontal member such that in a first state, the top lid seals the top end opening while in a second state allows fluid to flow to an inside portion of the rigid body.

Device for collecting water sample to concentrate diversified bacteria from different water depth

The present invention relates to a thermolabile caffeine fraction useful for an efficient-mediated genetic transformation in plant systems to develop desired traits in plant, and a method of preparing said fraction from tea leaves and also, an efficient and cost-effective method of introducing said-mediated genetic transformation into plant systems using said caffeine fraction of tea leaves.

The present invention relates to a thermolabile caffeine fraction useful for an efficient-mediated genetic transformation in plant systems to develop desired traits in plants, and a method of preparing said fraction from tea leaves and also, an efficient and cost-effective method of introducing said-mediated genetic transformation into plant systems using said caffeine fraction of tea leaves.

The present invention relates to an efficient and cost effective method of preventing growth of genetic transformant bacteriaafter transformation in plants by using tea leaf extract as a bactericide, wherein said method leads to elimination of common problem of polyphenol oxidation during transformation and thereby helps maintain regeneration potential in explants and also helps in increased transformation efficacy

Efficient method of preventing growth of microbial genetic transformant after transformation

The present invention relates to Production of transgenic tea ((L.) O. Kuntze) through biolistic.

Transgenic tea through biolistic using leaf explants

The present invention relates to use of inexpensive semi-refined kappa carrageenan as a seaweed polysaccharide in preparation of tough, biodegradable films exhibiting improved performance over films obtained from refined kappa carrageenan. The formulation requires no gelling salt and the only other essential components of the film are glycerol and water, the former being used as plasticizer as reported in the prior art. The films can be recycled and reprocessed if required. The performance of the films can be further enhanced by incorporating polyvinyl alcohol that lends toughness and clarity as also natural rubber latex that imparts greater elasticity and barrier properties. Films of optimum composition can be pulse heat sealed immediately after casting and used for preparation of soft capsules and pouches. It is possible to store solvents and oils in the pouches. In view of the more eco-friendly processing of semi-refined kappa carrageenan compared to refined kappa carrageenan, films made with the former would also effectively be 'greener'.

Process of preparation of biodegradable films from semi refined kappa carrageenan

The present invention relates to novel method for micropropagation of tea plants from explants obtained from completely folded, half opened or fully expanded leaves via callus phase, by culturing the explants on different media.

Method for microproduction of tea plants from leaf explants

The invention provides a one step method for micropropagation of tea plants from leaf explants via callus phase, wherein the explants are maintained in basal Murashige and Skoog medium (Murashige T. and Skoog F. A revised medium for rapid growth and bioassays with tobacco tissue cultures. Physiol. Plant. 15: 473-497; 1962) supplemented with vitamins like thiamine-HCl (0.05 to 2.0 mg/l), pyridoxine-HCl (0.25 to 1.5 mg/l) and nicotinic acid (0.25 to 1.5 mg/l) together with glycine (1.0 to 3.0 mg/l) and either 2.5, 5.0 or 7.5 mg/l 2,4-Dichlorophenoxy acetic acid for a period of 14-16 weeks, from the stage of induction of callus to rhizogenesis and shoot formation.

One step method for micro-production of tea leaves

The present invention describes a method for inducing improved seed germination in a high altitude medicinal plant, Royle through hot water treatment at 40&deg; C.-100&deg; C. for 30-120 seconds.
