Mannheim, Germany (PRWEB) November 06, 2013
The Biological Sciences Network ScienceIndex.com was established in 1998 to index the very latest news, headlines, references and resources from science journals, books and websites worldwide. The site covers news in all fields of biology, business, chemistry, engineering, geography, health, mathematics and society. In the field of Biological Sciences, the site has now included the two new sections Biotechnology and Ecology. While the Biotechnology section covers the utilization of bacteria, yeasts and other biological substances for industrial and manufacturing processes, and post-harvest processing of natural products, the Ecology section deals with the relationships between organisms and their environments.
ScienceIndex.com's Biological Sciences category including its new Biotechnology and the Ecology Sciences sections covers life and living organisms, including their structure, function, growth, origin, genetics, and distribution. The category now covers the ten disciplines agriculture, anatomy, biotechnology, ecology, environment, forestry, genetics, microbiology, physiology, and zoology. Users can receive alerts for newly published content in this category by subscribing to ScienceIndex.com's Biological Sciences RSS feed.
ScienceIndex.com's new Biotechnology section covers the utilization of bacteria, yeasts and other biological substances for industrial and manufacturing processes, and post-harvest processing of natural products. It currently contains 6,880 articles partly derived from over 60 scientific Biotechnology journals. The latest articles in this category are also available through a Biotechnology Sciences RSS feed. One of the latest additions to this section discusses the effects of yeast immobilization on bioethanol production. During the early stages of fermentation, immobilized yeast cells produced ethanol at a higher rate than free cells. The authors conclude that in addition to the high level of ethanol produced by cells immobilized on chamotte, the stability of this support and its low cost make it a promising material for biotechnologies associated with ethanol production. The authors of another recently published article highlight systems biology and biotechnology of Streptomyces species for the production of secondary metabolites. The authors review recent trends in the systems biology and biotechnology of Streptomyces species and conclude that investigations of novel secondary metabolites and their biosynthetic gene clusters have been more systematized with high-throughput techniques at the genome scale.
ScienceIndex.com's new Ecology section deals with the relationships between organisms and their environments. It currently contains 15,605 articles partly derived from 146 scholarly Ecology journals. The latest articles in this section are also available through an Ecology Research RSS feed. One recently included article in this section covers climate-induced late-Holocene ecological changes in Pichavaram estuary (India). The authors studied variation in sedimentology as well as freshwater and marine palynomorphs in ecological perspective in two sediment cores deposited since 3,440 and 3,630 cal BP. Since ~2750 cal BP there has been a dominance of marine forms, indicating fluvio-marine sediment deposition and suggesting the recent landward intrusion of seawater during weakened monsoon conditions. Another article demonstrates symbiodinium diversity within Acropora muricata and the surrounding environment. The authors examined spatial changes in Symbiodinium clades within the water column at two different time periods and compared these with other environmental pools and those within the dominant reef-building species at the study site. The dominant coral Symbiodinium were available in combinations of the environmental pools, indicating that the coral has the potential to obtain its symbionts from a variety of environmental sources.
The Sciences Social Network currently contains over 1.95 million posts distributed among its' 75 categories. 94,757 users contribute articles from 17,302 journals publishing within the scope of the site. Due to an continuously improved publishing process, the delay between original publication and appearance at ScienceIndex.com is no more than two hours. The site provides an advanced search feature which suggests up to ten closely related articles for a search and for every displayed post. This content is now also available through a Mobile Portal which automatically formats the site's content suitable for mobile devices.
