In this paper, the results obtained from the investigations performed on determination of the content of soluble dietary fibre component β –glucan in different cereals grown by conventional and organic farming method are presented. Because dietary fibre and its components have great importance for human and animal nutrition as well as health benefits, it was a need to investigate the content of β– glucan from cereal domestic origin. Standardized enzymatic–gravimetric method–a mixed–linkage β –glucan assay Megazyme Kit (Megazyme, Ireland) was used for determination of β –glucan content in 27 different cereal samples: barley, oat, rye and wheat, grown at three locations during 2013. The mean values of β– glucan content in cereals conventionally grown ranged from 34.41 ± 1.47 g.kg –1 db with barley, through 23.5 ± 4.52 g.kg –1 db and 15.61 ± 0.36 g.kg –1 db with oat and rye, respectively to 5.60 ± 1.02 g.kg –1 db with wheat. The mean values of β– glucan content in analyzed cereals which were organically grown ranged from 33.28 ± 2.34 g.kg –1 db with barley, 21.3 ± 1.87 g.kg –1 db with oat, 15.81 ± 2.30 g.kg –1 db with rye and to 6.04 ± 0.58 g.kg –1 db with wheat. Compared to the other cereals investigated, barley grown by either conventional or organic farming method proved to have the highest content of β –glucan demonstrating its good perspective in cereal processing and technology, food market and human and animal nutrition. The positive/negative correlations allow indirect evaluation of cereals in breeding work aimed at creation of forms with increased/decreased content of β– glucans in","PeriodicalId":8682,"journal":{"name":"Banat's Journal of Biotechnology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74513246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this research was to evaluate the effects of shortening replacement with pumpkin powder at 0 %, 20 % and 40 % with or without water level increment on rheological properties of cake batter and two properties of produced cake. Pumpkin powder was obtained from pumpkin flesh through drying, grinding and sieving processes. The rheological attributes of the batter and the specific volume and moisture content of cakes were examined using a rheometer, rapeseed displacement method and air–oven method, respectively. Increasing shortening replacement, enhanced viscosity (87.00 Pa.s), while increasing water in shortening–replaced treatments reduced it (11.30 Pa.s). Samples showed shear thinning behavior. In linear viscoelastic range, samples indicated solid viscoelastic behavior. Loss tangent, storage and loss moduli obtained from frequency sweep test, were investigated in three frequencies. In each frequency, with increasing shortening replacement, their viscoelastic properties enhanced. Contrary, increasing water amount in shortening reduced–batter samples, weakened system structuring. With increasing frequency, both moduli of treatments increased and the loss tangent of 20 % reduced–shortening cake without water level increment showed a more similar trend to the control (0 % replacement without increasing water amount). The moisture content of cakes containing pumpkin was greater than control. The specific volume of cake with 20 % replacement without additional water (2.68 cm/g) was similar to the control and higher than other shortening– replaced treatments. Therefore, this treatment was chosen as the best reduced–fat cake.

The experiment was carried out in the period 2014– 2015 at the Institute of forage crops (Pleven) and aimed to study the biological performances of alfalfa after application of mineral oil Akarzin, either alone and in combination with reduced doses of synthetic insecticide (Eforia 045 ZC). The alone and combined use of Akarzin had no phytotoxic effect on the crop and influenced positively on the relative water content and dry mass productivity (an increase by 5.2 to 8.7 % and by 10.1 to 29.2 %, respectively). The treatment with the synthetic products also had a favorable effect on the phytosanitary status of the crop and restricted the аttack by Pseudopeziza medicaginis. The combined application of Akarzin along with Eforia 045 ZC allowed reducing the applied dose of the insecticide up to 0.03 and 0.01 %, as the same time the achieved effect in regard to the productivity exceeded the one of self–application of Eforia 045 ZC in the highest dose (0.05 %). With a view to reducing the negative impact on environment a reduction of the application dose of the insecticide after combining it with the mineral oil is recommended as an environmentally friendly approach in conditions of conventional cultivation of alfalfa.

Secondary metabolites derived from plants have revealed therapeutic properties. Artemisinin and its derivatives are the most famous terpenoids in the Asteraceae family. Nowadays, numerous attempts have been done to improve the production rate of these kinds of terpenoids in biotechnological procedures which most of them are allocated to hairy root cultures using Agrobacterium rhizogenes (A4, A7, Ar15834, Ar9534, Ar9402, Ar318 and Ar50). In this study, we tried to investigate the effect different strains of A. rhizogenes on frequency of hairy root induction in A. annua. Explants were prepared from leaves of A. annua. Then they were soaked in A. rhizogenes solution to be infected. They were cultured in MS medium for 14 days. For decreasing plant necrosis, two different concentrations of 0.1 and 0.5 % were added to the medium as anti– oxidant. For hairy root induction approve, PCR method was applied. Hairy roots were obvious in plantlets on 1⁄2 MS medium culture. The presence of T–DNA in different transformed lines of hairy roots was investigated by PCR. The results indicated that making 0.5 % ascorbic acid MS Medium will lead to a dramatic decrease (about 80 %) in plantlet’s browning. In addition, the highest and lowest transformation rate of 79 % and 24 % were yielded, infecting the leaf explants of A. annua by A7 and Ar318 strains respectively. To sum it up, it was shown that all mentioned strains are capable to induce hairy root in A. annua by the help of ascorbic acid as an inhibitor for plantlet’s browning. Because of hormone–autotrophic feature and great lateral branches of hairy roots, the induced hairy roots of A. annua can be applied to increase artemisinin production in pharmaceutical industry.

The eight male domestic dogs (3–4 years old, weighing 20–30 kg) were used. Bone formation was assessed by using of OEW as kind of biomaterial that has flexibility and jelly shape with high compatibility. The implant was harvested after 4 and 8 weeks, and the area of new bone formation was quantified by radiology and densitometry studies. The highest bone formation was achieved with the OEW treatment, and it was significantly higher than that achieved with the empty treatment. The quantity of new bone at end of 8 weeks was greater than at 4 weeks in treated group. The researcher also show that Using OEW, the bone regeneration significantly increased within the implanted site in the biomaterial group, in the second month of the experiment, when compared to the control group. Furthermore, bone regeneration was significantly higher in the implant treatment biomaterial site of individual OEW, after implantation times, it’s showed little effect in enhancing bone regeneration 4 weeks post– implantation. Overall, it can be concluded that OEW (safe, cheap, and easily available) is a potent osteoidinductive component that plays critical role during bone regeneration and repairing in animal model.
