EFFECT OF SOME PROBIOTIC BACTERIA ON THE REDUCTION OF AFLATOXIN B1 PRODUCTION IN STORED ARABICA COFFEE BEANS

F. Radu, S. Popescu, L. Rotariu, A. Cozma, M. Butnariu
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT Aflatoxin B1 (AFB1) contamination of coffee beans continues to be a serious issue regarding livestock productivity and human health. AFB1 (secondary metabolites produced by a larger number of Aspergillus spp.) is classified as a Group I carcinogen by the International Agency for (...)


EFFICACY OF BIOCHAR WITH IMMOBILIZED MICROBES FOR SOIL FERTILIZATION

S. Selivanovskaya, P. Galitskaya, K. Karamova, K. Kanunnikov
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT The issue of biochar application as a non-conventional fertilizer is of growing interest currently. Biochar is a product of the pyrolysis of organic waste for example and unlike conventional fertilizer, biochar is a long-acting agent. The use of such fertilizer should not only (...)


ESTIMATION OF EFFICIENCY OF USE OF VEGETABLE OILS FOR RE-CEPTION OF BIOFUEL BY A METHOD OF ENZYMATIC CATALYSIS

V. Shcherbakova, A. Krasnoshtanova, V. Panfilov
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT Biodiesel is a relatively new type of environmentally friendly fuel, which is made from renewable resources. Biodiesel is a mixture of methyl or ethyl esters of fatty acids. It is obtained by re-esterification of vegetable oils or others fat-containing substrate, including animal (...)


EVALUATION OF WHEAT DOUGH FERMENTATION PROCESS USING A REACTOR AND MATHEMATICAL MODELLING

A. Istudor, G. Voicu, M. Stefan, G. Constantin, G. Muscalu
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT The study presents the comparative analysis between pressure and carbon dioxide charts obtained after measuring a series of fermentation processes. Doughs used for measurements were obtained from different quality/extraction flours, type 650 and whole wheat (1850). Gathered data was (...)


COLLOIDAL SILICA GRANULES OF CHICKEN MANURE BIOCHAR INCREASE PLANT BIOMASS AND MICROBIAL COUNT

P. Kuryntseva, M. Rudakova, A. Gordeev, P. Galitskaya, S. Selivanovskaya
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT Pyrolysis is considered as an effective and alternative way to treat organic waste and to obtain pyrolysis fuels as well as biochar. The latter may be used for different purposes in industry and agriculture, including use as a long term fertilizer. Biochar, after pyrolysis, is (...)


ANALYSIS OF THE GARLIC LANDRACES IN THE WEST OF ROMANIA USING THE FLOWCYTOMETRY METHOD

A. A. Petcov, D. Camen, M. Moatar, C. Petolescu, A.Turc
Wednesday 19 December 2018 by Libadmin2018
ABSTRACT For to determinate the DNA content and analysis of cell distribution in different phases of the cell cycle, flow cytometry was used. The exact measurements of a large number of nuclei by flow cytometry, fluorescently labeled by passing a laser beam (excitation), which marks each (...)
