Valorization of agro-industrial waste resources is today’s main focus for agribiotechnologists. This research work was designed to valorise tea industrial waste, i.e., manufactured by-products from crush-tear-curl (CTC) factory. Physicochemical analysis has been carried out characterize treated soil. Pot experiment with cowpea [Vigna unguiculata (L.) Walp.] considered study the impact on plant ...

In a previous study (Z Y. Wang et ci., Cancer Res., 52: !!62—1!70, !992),wefoundthatadministrationof a waterextractof greentealeaves as the sole source of drinking fluid inhibited ultraviolet B light (UVB) Induced carcinogenesis in SKH-! mice previously Initiated with 7,12dimethylbenz[alanthncene (DMBA). In the present study, we compared the effects of black tea, green tea, decaffeinated blac...

The main goal of this study was to compare effects of ethanol-soluble fractions prepared from various types of teas on sucrose-induced hyperlipidemia in 5-week old male Sprague-Dawley rats. Rats (n 5 6–8 per group) weighed approximately 200 g were randomly divided into control diet, sucrose-rich diet, green tea, oolong tea and black tea groups. Control-diet group was provided with modified AIN-...

The European circular economy targets and waste policies have gradually focused on bio-waste, which is considered one of several key streams urgently needed to develop strategies for their selective collection. In non-intensive urban regions, a collection challenge due the dispersion bio-waste producers. This work intended characterize producers, in Planalto Beirão region (Portugal) define mana...

Microbial communities are ubiquitous in both natural and artificial environments. However, microbial diversity is usually reduced under strong selection pressures, such as those present in habitats rich in recalcitrant or toxic compounds displaying antimicrobial properties. Caffeine is a natural alkaloid present in coffee, tea and soft drinks with well-known antibacterial properties. Here we pr...

Pectinases are the growing enzymes of biotechnological sector, showing gradual increase in their market. They hold a leading position among the commercially produced industrial enzymes. These enzymes are ecofriendly tool of nature that are being used extensively in various industries like wine industry; food industry; paper industry for bleaching of pulp and waste paper recycling; in the proces...

BACKGROUND Tea is the world's most popular non-alcoholic beverage. China and India are known to be the largest tea producing countries and recognized as the centers for the domestication of the tea plant (Camellia sinensis (L.) O. Kuntze). However, molecular studies on the origin, domestication and relationships of the main teas, China type, Assam type and Cambod type are lacking. METHODOLOGY...

Spent tea leaves (STL), a solid waste that is available in large amounts worldwide, was investigated as a potential low-cost adsorbent for the removal of two azo dyes, Reactive Green 19 (RG19) and Reactive Violet 5 (RV5), from contaminated waters. Preliminary experiments conducted on untreated STL showed that this material exhibited very low removal efficiencies (<10 %). By contrast, thermal ac...

Several examples of laser in situ monitoring of combustion processes are presented. Using a frequency modulated (13)CO(2) waveguide laser, in situ concentrations of NH(3) down to 1 ppm were measured at temperatures up to 600 degrees C in waste incinerators and power or chemical plants. Following ignition of CH(3)OH-O(2) mixtures by a TEA CO(2) laser, gas temperature profiles were measured using...
