Meat and meat products are highly prone to microbial deterioration since they are rich in essential nutrients and perishable in nature and if they are not properly preserved, public health problems may occur. Recently, in order to increase the microbial quality of meat and meat products, novel ingredient systems that are associated with natural and organic foods, are applied. Many studies have ...

Trichoderma spp. are fungi that occur worldwide. Recent studies show that they are not only parasites of fungal plant pathogens but also can produce antibiotics. In addition, certain strains can induce systemic and localized resistance to several plant pathogens. Moreover, some strains may enhance plant growth and development. The potential of Trichoderma species used as biological agents of pl...

working with flax and the flax rust fungus, defined plant–pathogen interactions genetically, producing the gene-for-gene hypothesis1. This classic concept is based on the observation that disease resistance in plants commonly requires two complementary genes: an avirulence (Avr) gene in the pathogen and a matching, resistance (R) gene in the host. The biochemical interpretation of this hypothes...

Soil flooding in wetlands is accompanied by changes in soil physical and chemical characteristics. These changes include the lowering of soil redox potential (Eh) leading to increasing demand for oxygen within the soil profile as well as production of soil phytotoxins that are by-products of soil reduction and thus, imposing potentially severe stress on plant roots. Various methods are utilized...

Lambic sour beers are the products of a spontaneous fermentation that lasts for one to three years before bottling. The present study determined the microbiota involved in the fermentation of lambic beers by sampling two fermentation batches during two years in the most traditional lambic brewery of Belgium, using culture-dependent and culture-independent methods. From 14 samples per fermentati...

Nature's repertoire of biosynthetic transformations has recently been recognized to include the Diels-Alder cycloaddition reaction. Evidence now exists that there are enzymes that mediate the Diels-Alder reaction in secondary metabolic biosynthetic pathways. 2002 marked the 100th anniversary of Alder's birth and 75 years since the discovery of the Diels-Alder reaction. It would appear that livi...

A study of the metabolic pathways of H(3)-thymidine utilization in buds of Lilium longiflorum and root tips of Vicia faba was undertaken in order to obtain information that might explain the binding of H(3) from H(3)-thymidine in the cytoplasm of these plants. H(3)-thymidine was administered for various periods of time, the tissues were fixed and processed in the manner routinely used in prepar...

The development of radioprotective agents has been the subject of intense research in view of their potential for use within a radiation environment, such as space exploration, radiotherapy and even nuclear war. However, no ideal, safe synthetic radioprotectors are available to date, so the search for alternative sources, including plants, has been on going for several decades. In Ayurveda, the...

Article Type: Review There are many difficulties and deficiencies in chemotherapeutic drugs especially drug resistances that appear in cancer chemotherapy. In spite of the fact that chemotherapeutic drugs are very effective, severe side effects limit the use of these drugs. People have to pay more attention to natural sources of cancer drugs to increase the anti-cancer agents present in the dru...
