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...

Slope exposure is known to affect soil biogeochemical processes in mountainous forest ecosystems, but little attention has yet been paid its influence at a aggregate scale. Therefore, we evaluated the effects of slope (north- vs south-facing slope) on physico-chemical and microbiological properties bulk dry-sieved water-stable size fractions both organic (OF) mineral (AE) horizons an Italian al...

this paper deals with the suitability of agricultural and municipal organic wastes as growing media components for ornamental plants. nine growing media prepared by mixing the main components of peat (p), hazelnut husk (h) and maize straw (m) with the fertilizer sources of municipal solid waste compost (c), bio-solid (b) and poultry manure (pm) were compared against soil-based (c1) and peat-bas...

1. A considerable advance has been made in the study of the fulvic extract of soil organic matter. A new method has been introduced whereby the fulvic extract is separated by a selective adsorption technique into four distinct fractions. 2. These fractions have been obtained from the fulvic extracts from four widely diverse types of soil. 3. A preliminary examination of the chemical properties ...

Large amounts of fertilizers and pesticides applied annually to agricultural soils improve the physical and chemical properties of soil but, when they are applied without control they can cause serious environmental problems. The farms of Tizayuca in Hidalgo State produce about 30000 tons of manure per day, which are applied indiscriminately in the same region for agricultural use. The aim of t...

UNLABELLED Physico-chemical properties of amino acids can be used to study protein sequence profiles, folding and function. We collated 242 properties for the 20 naturally occurring amino acids and created a dataset. The dataset is available as a database named APDbase( Amino acid Physico-chemical properties Data base). The database can be queried using either key words describing physico-chemi...
