triticale (x triticosecale wittmack) is a hybrid seed plant result from wheat and secale. this seed has high amylolitic and protelytic activities, introducing it as adjuncts in mashing process. in this study, influence of malting process on physico-chemical properties variety of barley (namely sahra) and triticale and malt quality of them were investigate. malt of barley was selected as referen...
soil organic matter is an indicator of soil, agriculture and environmental quality, playing important roles in soil strength and sound environmental functions. size and chemical fractionation of soil organic matter are long-standing approaches in clarifying their key role in soil processes. twenty seven surface samples (0-20 cm) and 6 pedons from different landform units were sampled and descri...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
Background: Soil is a crucial and remarkable component of the terrestrial ecosystems. The objective this study to analyze macronutrients micronutrients in order understand suitability soil for cultivation crops selected sites. In present physicochemical analysis was carried out by analyzing parameters i.e. pH, organic carbon potassium etc. Methods: Four samples were collected 2017-2018 during w...
In the course of our search for new antibiotics produced by Streptomyces sp., a water-soluble antibiotic, effective against gram-negative bacteria, was obtained from the nitrate of a culture broth of Streptomyces No. 5879 isolated from a soil sample collected in Aizu area (Fukushima prefecture). Antibiotic No. 5879 appears to be a novel one from its physico-chemical and biological properties, a...
analyses and thermal infrared channels 4 and 5 NOAA- AVHRR images. This research was carried out in Lut Desert located in center of sub-tropical divergence dominant in' Iranian plateau. The physical and thermal properties of the various desert surfaces have been determined using correlation relationships between the desert variables including: dark sand, normal sand, marl, saline soil, soil dep...
In the course of a screening program for novel antibiotics showing antitumor activity, a cyclic peptide antibiotic sohbumycin was isolated from the culture broth of Streptomyces sp. No. 82-85, which had been isolated from a soil sample collected in Kanagawa prefecture, Japan. The isolation and physico-chemical properties of sohbumycin and fermentation and taxonomy of the producing organism, Str...
The effect of Indigenous microorganisms (IMO’s) on the native soil was investigated in the present study. Supplementation of IMO’s suspension to the soil alters the physico-chemical, biological and enzyme properties of the soil. These alternations include decreases in P from 7.2 to 6.8, increase in electrical conductivity 0.36 to 1.21 (μmohs/cm), water holding capacity 0.36 to 2.2ml/g of soil o...
