Download or read book Bacterial Biosurfactants written by Bolin Kumar Konwar and published by CRC Press. This book was released on 2022-03-10 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new volume offers comprehensive coverage of bacterial biosurfactants, the competitive new area of research that has exciting potential application in agriculture and petroleum exploration. The book helps readers to understand the synthesis of biosurfactants by some specific bacteria, their culture, and extraction toward use in bioremediation and enhanced crude oil recovery. The volume covers the gamut of topics in bacterial biosurfactants in nanostructure, including their comparison to synthetic surfactants, their interaction with microorganisms, and their biochemistry, characterization, genetics of production, bioremedial effects, and more. The volume also explores the myriad uses of bacterial biosurfactants, including in laundry detergents, cosmetics, food production, petroleum, agriculture, medicine and therapeutics, environment, metallurgy, etc. Attention to biosurfactants has been gradually increasing in recent years due to the possibility of their production through fermentation technology and their potential applications in environmental protection. Despite their numerous advantages over synthetic chemical surfactants, biosurfactants have been unable to compete with chemically synthesized surfactants due to high production costs in relation to the inefficient bioprocessing techniques, poor strain productivity, and use of costly substrates. This volume helps to identify the factors that need to be addressed to reduce the cost of production of biosurfactants.
Download or read book Survismeter written by Man Singh and published by CRC Press. This book was released on 2019-01-30 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the survismeter, a new invention that widely covers and determines PCPs of various molecules and experimentally measures the thermodynamic and kinetic stabilities of nanoemulsions. It unveils how a survismeter can measure surface tension, interfacial tension, wettability, viscosity, friccohesity, tentropy, rheology, density, activation energy, and particle size. It discusses novel models of molecular science that can be applied in the formulation and study of activities of functional molecules through their PCPs. It also introduces the new concept of friccohesity, which has emerged as an excellent substitute of viscosity and surface tension in experimental measurements as it does not require density measurements. It shows that the science and technology of the survismeter and friccohesity have become an inevitable part of scientific research, substantially integrating the domain of perfect industrial and academic formulations.

Download or read book Biosurfactants written by Ramkrishna Sen and published by Springer Science & Business Media. This book was released on 2010-12-31 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: The microbial world has given us many surprises including microbes that grow under extremely harsh conditions (122C at 40 MPa), novel metabolisms such as the uranium and perchlorate reduction, and novel chemicals that can be used to control diseases. We continually face new and difficult problems such as the need to transition to more carbon-neutral energy sources and to find eco-friendly chemicals and to find new drugs to treat disease. Will it be possible to tap into the seemingly limitless potential of microbial activity to solve our current and future problems?The answer to this question is probably yes. We are already looking to the microbial world to provide new energy sources, green chemicals to replace those made from petroleum, and new drugs to fight disease. To help us along these paths, we are deciphering how microorganisms interact with each other. We know that microbial populations interact and communicate with each other. The language that microbes use is chemical where small molecules are exchanged among different microbial cells. Sometimes, these chemicals suppress activities of competitors and could be used as antibiotics or may have other therapeutic uses. Other times, the chemicals stimulate complex responses in microbial populations such as fruiting body or biofilm formation. By understanding the conversation that microbes are having among themselves, e. g.
Download or read book Structure Analysis by Small Angle X Ray and Neutron Scattering written by L.A. Feigin and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 339 pages. Available in PDF, EPUB and Kindle. Book excerpt: Small-angle scattering of X rays and neutrons is a widely used diffraction method for studying the structure of matter. This method of elastic scattering is used in various branches of science and technology, includ ing condensed matter physics, molecular biology and biophysics, polymer science, and metallurgy. Many small-angle scattering studies are of value for pure science and practical applications. It is well known that the most general and informative method for investigating the spatial structure of matter is based on wave-diffraction phenomena. In diffraction experiments a primary beam of radiation influences a studied object, and the scattering pattern is analyzed. In principle, this analysis allows one to obtain information on the structure of a substance with a spatial resolution determined by the wavelength of the radiation. Diffraction methods are used for studying matter on all scales, from elementary particles to macro-objects. The use of X rays, neutrons, and electron beams, with wavelengths of about 1 A, permits the study of the condensed state of matter, solids and liquids, down to atomic resolution. Determination of the atomic structure of crystals, i.e., the arrangement of atoms in a unit cell, is an important example of this line of investigation.

Download or read book Surfactant Aggregation written by J.H. Clint and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface Active Agents (surfactants) are vital components in biological systems, form key ingredients in consumer products and play an important role in many industrial processes. For example, cell membranes owe their structure to the aggregation of surfactants known as lipids which form a major component of the membrane. Other natural surfactants occur in the digestive system, in the lungs, and even in such substances as crude oil. Man-made surfactants are used in a wide range of domestic and industrial products and processes. In addition to detergents and personal care products, surfactants have found uses in almost every branch of the chemical industry as well as in several other industries. These include dyestuffs, fibres, mineral process ing, oil field chemicals, paints, pesticides, pharmaceuticals and plastics. Surfactants are versatile materials which are manufactured in a huge variety of forms to suit all of these applications. As a result of their importance, the technical literature on all aspects of surfactant behaviour is now very extensive. Surprisingly, however, the treatment in textbooks has been somewhat fragmented, often in the form of conference proceedings or edited, multi-authored works, both lacking in continuity.

Download or read book Handbook of Surfactants written by M.R. Porter and published by Springer. This book was released on 2013-04-17 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: The worldwide consumption of surfactants now exceeds several million tonnes per annum. Six ofthe major types represent approximately 80% ofthe volume consumed, whereas the remaining 20% is made up of approximately 40 different chemical types. Commercially produced surface active agents are not pure chemicals, and within each chemical type there can be tremendous variation. Technical staff who are not familiar with surfactants are frequently bewildered by the enormous variety of different products on the market and the vast body of literature which exists on the composition and properties of surfactants. The selection of the best surfactant for any given use therefore becomes a major problem. This volume arose from the clear need to have available a simple reference book summarising the different types of surfactants on the market and their properties. The concept and structure of the book evolved from early attempts to define chemical structure/property relationships of all the different types of surfactants commercially available, into a simple handbook providing essential background information for the surfactant user. It is realised that most users will be developing their own data bank of structure/end use property relationships and they will therefore be the experts on end use.
