This paper presents recent information (period 2015-2017 evaluation) about the species with the most abundant development in the past years along the Romanian Black Sea coast, namely the green algae Ulva rigida and Cladophora sp. These two species are considered opportunistic, with a high reproductive capacity and a frequent distribution at the Romanian shore, with an abundant development between 0-3 meters depth, so it is considered accessible and easy to collect the algal material. In the present study the bioch...

Salinity is one of the major environmental stress factors for crops that adversely affect plant growth and development. High concentrations of salt in the soil cause ion toxicity, osmotic stress, oxidative stress, nutrient deficiencies and imbalances perturbing important physiological and biochemical processes. To minimize the effects of salinity, the plant develops a large array of responses involving a complex enzymatic and non-enzymatic antioxidant system, ion transport and compartmentalization of deleterious i...

In recent years, numerous works have been devoted to sturgeon breeding. One of the reproduction problems of sturgeon fishes is the low survival rate of larvae and fry, which is associated with the impact of various negative factors on the growth and viability of the young in the early stages of its development. One of the ways to increase the viability of sturgeon larvae is to introduce components into the starting compound feed that regulate metabolic processes, including the resistance of early juveniles to unfa...

Grape juice consumption has increased significantly in recent years due to the beneficial health effects showed by products derived from grape. Grape juice is the unfermented drink obtained from simple must, sulfated or concentrated, from healthy, fresh and ripe grapes. When grape juice is processed with the aim of obtaining a shelf-stable product, its product shelf-life is determined by a best-before date, which is limited due to physical and (bio) chemical reactions. With the change of these properties, the micr...

The paper focuses on the results of the research study of the must and wine of the Georgian, aboriginal, rare variety of grapevine called "Khikhvi". The naturally and artificially (IR) fermented chacha was used in the experiment. The objective of artificial fermentation was to shorten the prolonged fermentation time of the freshly pressed chacha. This excludes the activation of acetic acid bacteria in the chacha under the influence of air oxygen. A rapid redox occurs in the liquid in short period by infrared irrad...

It is necessary to determine the amount of starch in order to find effective methods of controlling it in technological flows of paper mills. Enzymatic methods for starch determination based on the selective action of amylolytic enzymes on starch are promising. Water-soluble low molecular weight dextrins are formed when starch is treated with alpha-amylase. Dextrins are then hydrolyzed by glucoamylase to glucose, which is determined by various methods.

Previously it was believed that stress influence on microorganisms is only negative, reducing the efficiency of biosynthesis. However, it has been shown now that with the use of controlled stress, it is possible to increase the efficiency of microbial cultivation processes. Among other types of stress, oxidative stress is the most significant. When microorganisms are exposed to oxidative stress agents, breaks can occur in nucleic acid molecules as well as of protein molecules, in addition to this, the blockage of ...
