mRNA, inhibition to DNA polymerase, and degradation of mRNA for determining the RNA quality using standard RNA. It would be possible to know yield of mRNA and inhibition of the enzyme reaction by adding standard RNA before RNA extraction and looking at standard RNA loss. Degradation was evaluated by comparing the differences in the 3’ and 5’ regions of the RNA. In our study, it was demonstrated that in the crude extract of Saccharomyces cerevisiae, degradation was comparatively higher at the 3’ end

Naproxen is a one of the most popular non-steroidal anti-inflammatory drugs (NSAIDs) entering the environment as a result of high consumption. For this reason, there is an emerging need to recognize mechanisms of its degradation and enzymes engaged in this process. Planococcus sp. S5 is a gram positive strain able to degrade naproxen in monosubstrate culture (27%). However, naproxen is not a sufficient growth substrate for this strain. In the presence of benzoate, 4-hydroxybenzoic acid

Copper becomes more and more important in the electronic industry. This metal is more resilient than conventional materials (like aluminium) due to the higher electrical and thermal conductivity. During several electrical stress pulses the copper changes. The surface can melt up and cracks and voids can develop inside the copper specimen. In this paper we use acoustic emission testing to analyse copper degradation especially of copper and copper traces. It is evaluated if an acoustic wave

Nitroaromatic compounds are present in the environment mainly as industry products. They pose a serious risk to our health (often exhibiting strong mutagenic and carcinogenic effect) as well as to the environment. Most of the nitroaromatic compounds are stable due to considerable resistance to degradation and they persist in the environment for a long time. In this review, we present the current state of knowledge concerning biodegradation of nitroaromatic compounds. In the first part, general

Polycyclic aromatic hydrocarbon (PAHs) are common soil contaminants of concern due to their toxicity toward plants, animals and microorganisms. The use of indigenous or added microbes (bioaugmentation) is commonly used for bioremediation of PAHs. In this work, the biodegradation rates and changes in the bacterial community structure were evaluated. The enrichment culture was useful for unambiguously identifying members of the soil bacterial community associated with PAH degradation and yielded

Among all strains, the most effective in degradation of cellulose and xylose was T. harzianum and T. virens, especially those isolated from forest wood, forest soil or garden and mushroom compost. The results of this work confirmed that numerous strains from the Trichoderma species have high cellulose and xylan degradation potential and could be

For many years, various research investigations have been carried out on the application of K2FeO4 for the degradation of various pollutants in water and wastewater. In this paper authors focused on pollutants deriving from the industry and mining like: cyanides, organic compounds, dyes and also removal of algae from potable water.

Special attention of researchers is focused on endophytic bacteria. These bacteria can promote the growth and development of plants and, consequently, increase their biomass. They may also affect the bioavailability of organic pollutants in the soil. An important advantage resulting from the application of this group of microorganisms to

Metal-detector performance depends heavily on the sensor head. Errors in coil placement within the head can lead to degradation in detector performance. Electromagnetic modelling of typical very-low-frequency detector heads shows the effect of coil placement errors on detector sensitivity. Provided the bucking coil ‘tracks’ the receive coil, required error corrections can remain small. A correctly-aligned head could detect a gold ring target at a range of about 12 cm.

The typical strategies of the aerobic degradation of cresols include the use of monooxygenase and dioxygenase enzymes. Thanks to these enzymes, atoms of molecular oxygen initiate fission of the aromatic

The results showed that two days of fermentation was sufficient to increase the viable count of bacteria, lactic acid levels and degradation of soybean protein in fermented soybean meal at the initial moisture content of 50%. The pH value, lowering sugar content and oligosaccharides in fermented soybean meal, was significantly reduced at the initial moisture content of

Chitin, an insoluble linear β-1,4-linked polymer of N-acetylglucosamine, is the second most abundant polysaccharide in nature after cellulose. It is present in cell walls of several fungi, exoskeletons of insects and crustacean shells. Enzymatic hydrolysis of this polysaccharide is carried out in the presence of glycoside hydrolases-chitinases. They are produced by microorganisms, insects, plants, and animal, but it is the bacterial chitinases which play a fundamental role in degradation

As a component of the ubiquitin-proteasome system (UPS), parkin plays a key role in the degradation of damaged or misfolded proteins, and in the removal of defective mitochondria via mitophagy (Geisler

Progressive development of civilisation results in an increase in production and consumption, and thus increased accumulation of waste. A significant part of that waste are packaging materials made from polymers of petrochemical origin. They are difficult to remove from the environment due to the long degradation times and hazardous decomposition products. The decomposition time of conventional polymers is estimated in tens, hundreds, and even thousands of years. In addition
