Abstract Microbial weathering processes can significantly promote soil properties and enhance rock to soil ratio. Some soil-inhabiting bacteria exhibit efficient rock-dissolution abilities by releasing organic acids and other chemical elements from the silicate rocks. However, our understanding of the molecular mechanisms involved during bacterial rock-dissolution is still limited. In this study, we performed silicate rock-dissolution experiments on a novel Pseudomonas sp. NLX-4 strain isolated from an over-exploited mining site. The results revealed that Pseudomonas sp. NLX-4 strain efficiently accelerates the dissolution of silicate rocks by secreting amino acids, exopolysaccharides, and organic acids. Through employing genome and transcriptome sequencing (RNA-seq), we identified the major regulatory genes. Specifically, fifteen differentially expressed genes (DEGs) encoding for siderophore transport, EPS and amino acids synthesis, organic acids metabolism, and bacterial resistance to adverse environmental conditions were highly up-regulated in silicate rock cultures of NLX-4 strain. Our study proposes a novel bacterial based approach for improving the ecological restoration of over-exploited rock mining-sites.

The effect of presowing seed treatment on various concentrations of dicarboxylic (organic) acids on the sowing characteristics of spring barley has been studied. Seeds were treated with organic acids obtained by exposing cuttings to the radiation with a dose of 100 kGy and consequent hydrolysis, in concentrations: 1•10-7 %; 1•10-9; 1•10-11; 1•10-13 and 1•10-15 % on a laboratory rotary machine RVO-64 for one day before laying for germination. Distilled water was used for the control case. The rate of application of the working solution calculated as 10 liters / ton of seeds. Seeds were germinated in filter paper rolls in accordance with GOST 12038-84 requirements. The temperature was maintained at +24 ° C in the thermostat where the glasses with rolls were placed. For determination of germinative power and laboratory germination the sprouted seeds were evaluated after three and seven days, respectively. In laboratory experiments it was established that the treatment of barley seeds of varieties Zazersky 85, Nur and Vladimir with organic acids (OK) in different concentrations had both a stimulating and a negative effect. On the Zazersky 85 variety, in variants with acid concentrations of 1•10-9 and 1•10-11, an increase in germination energy (EP) by 2-4% and a significant decrease (by 3-4%) of laboratory germination (LV) of barley seeds were noted. On the Nur variety, the increase in EP was observed at 4% (concentration 1•10-11), LV and seed growth force (CPC) by 2-7% at a concentration of 1•10-7 and in the dose range 1•10-11 - 1•10-14 compared to the control values. On the grade of Vladimir, an increase in EP, LV, and CPC was found to increase by 1-6% at concentrations OK 1•10-7 and 1•10-13. It was shown that the treatment of seeds with acids led to an increase in the length of the germ in all studied varieties (by 3-9%) and dry biomass of 7-day-old seedlings - by 3-6%. Consequently, the treatment of seeds with a mixture of dicarboxylic acids has a stimulating effect on the sowing quality of spring barley.

Production of plant products, including juices around the world increases continuously. In the fruit and vegetable juices contain a significant amount of monosaccharides (glucose and fructose), organic acids, vitamins, phenolic compounds, mineral substances and other biologically active components that determine the nutritional and dietary value. For the prevention of various diseases associated with impaired metabolic processes, we developed a new technology of preparation of food by blending juice of pumpkin, quince and persimmon. Thus prepared organic blended juice contains a substantial amount of free glucose and fructose, different phenolic compounds, a sufficient amount of organic acids, mineral elements, including iodine and other components that determine its nutritional and biological value. In prepared juices were evaluated the quantitative indicators of β-carotene, vitamin C, glucose and fructose, sucrose, starch, pectin substances. Also in the atomic absorbtion spectrometer Analyst 400 (PerkinElmer, USA) was analyzed content of the organic acids and phenolic compounds. Prepared juices were tested in accordance with 10 point scoring scale. It is established that all juices contain a sufficient amount of the minerals. In pumpkin and quince juices not contain iodine while it presents in sufficient amount in persimmon juice that’s why in the blended juice mineral in addition to mineral elements iodine are contained. In pumpkin and persimmon aliphatic acids are contained in small amount. For this reason during the blending process was used quince juice which is rich in aliphatic acids. The blended juice is light straw color, with delicious flavor, a slight astringent property and a balanced taste.
