In the course of screening for antibacterial antibiotics from actinomycetes, a new antibiotic, OM704 A, has been isolated from the culture broth of strain OM-704, a soil isolate identified as Streptomyces sp. This antibiotic was active against Gram-positive bacteria. The present paper deals with the taxonomy of strain OM-704 and the fermentation, isolation and biological and physicochemical pro...
The need of taxonomy is vital for knowledge sharing. This need has been portrayed by through-life engineering services/systems. This paper addresses this issue by repair process taxonomy development. Framework for repair process taxonomy was developed followed by its implementation. The importance of repair process taxonomy has been highlighted.
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...
in response to the demand for soil spatial information, the acquisition of digital auxiliary data and their matching with field soil observations is on the increase. with the harmonization of these data sets, through computer based methods, the so-called digital soil maps are increasingly being found to be as reliable as the traditional soil mapping practices, and with no prohibitive costs. the...
Peatlands are a subset of wetlands that have accumulated significant amounts of soil organic matter. Soils of peatlands are colloquially known as peat, with mucks referring to peats that are decomposed to the point that the original plant remains are altered beyond recognition (Chapter 6, SSSA 2008). Generally, soils with a surface organic layer >40 cm thick have been classified as Histosols in...
80% of arable land in Africa has low soil fertility and suffers from physical soil problems. Additionally, significant amounts of nutrients are lost every year due to unsustainable soil management practices. This is partially the result of insufficient use of soil management knowledge. To help bridge the soil information gap in Africa, the Africa Soil Information Service (AfSIS) project was est...
Rock formation as parent material in Pagedongan Village, Banjarnegara influences the properties of soil formed. The purpose this research was to identify morphology and classification according USDA Taxonomy, National Soil Classifications, World Reference Base for Soils. This study uses a survey method by determining observation points based on rock formation, namely Peniron Formation, with pyr...
Pseudomonas Isolation and Identification: An Introduction to the Challenges of Polyphasic Taxonomy †
The ability to isolate an organism in pure culture from the environment is a manageable task for undergraduate students; the identification of that organism requires integration of both genotypic and phenotypic data and illustrates the challenges inherent in contemporary bacterial taxonomy. In this ten-laboratory period series of exercises, students isolate a strain of Pseudomonas from soil and...
A plot study was conducted to assess changes in Cd phytoavailability to a tomato cultivar in an agricultural soil in Southeastern Spain amended in two different ways (A and B), under controlled conditions. The experimental soil corresponded to a fine-loamy carbonatic thermic Calcidic Haploxeroll (Soil Survey Staff, Keys to Soil Taxonomy, eighth ed., USDA, Washington, 1998). (A) Soil was amended...
