TL;DR: The efficacy of SVD denoising method in electronic nose data analysis is demonstrated by analyzing five data sets available in public domain which are based on surface acoustic wave sensors, conducting composite polymer sensors and the tin-oxide sensors arrays.
Abstract: This paper analyzes the role of singular value decomposition (SVD) in denoising sensor array data of electronic nose systems. It is argued that the SVD decomposition of raw data matrix distributes additive noise over orthogonal singular directions representing both the sensor and the odor variables. The noise removal is done by truncating the SVD matrices up to a few largest singular value components, and then reconstructing a denoised data matrix by using the remaining singular vectors. In electronic nose systems this method seems to be very effective in reducing noise components arising from both the odor sampling and delivery system and the sensors electronics. The feature extraction by principal component analysis based on the SVD denoised data matrix is seen to reduce separation between samples of the same class and increase separation between samples of different classes. This is beneficial for improving classification efficiency of electronic noses by reducing overlap between classes in feature space. The efficacy of SVD denoising method in electronic nose data analysis is demonstrated by analyzing five data sets available in public domain which are based on surface acoustic wave (SAW) sensors, conducting composite polymer sensors and the tin-oxide sensors arrays.

TL;DR: This review will consider the basic principles involved and factors affecting extractive fermentation, technical aspects and technological developments like use of ligands and surfactants to improve separation, recent trends and future prospects of Extractive fermentation systems.
Abstract: The efficiency of any fermentation process depends largely on downstream processing which ensures the purity and quality of the biochemicals. Since many biomolecules have narrow tolerance limits of pH, temperature, osmotic pressure, surface charges, etc. the extraction and isolation techniques should be specific and compatible to the product. Therefore, it is not surprising that about 60-90% of the cost of a biological process is that expended on downstream processing. Aqueous two-phase systems (ATPS) result from the incompatibility or immiscibility of polymers, either between two polymers in water or a polymer solution with a salt solution. ATPS contain about 80-90% water and thereby can provide an excellent environment for cells, cell organelles and biologically active substances. 'Extractive fermentation' is an emerging technique that involves the use of ATPS-based in situ fermentation processes. The advantages of such a system include rapid mass transfer due to low-interfacial tension, ease of operation under continuous mode, rapid and selective separation, biocompatibility, separation at room temperature, easy and reliable scale-up of bench scale results to production scale, ecofriendliness, suitability for systems with product inhibition and high yield of biomolecules. In this review, we will consider the basic principles involved and factors affecting extractive fermentation, technical aspects and technological developments like use of ligands and surfactants to improve separation, recent trends and future prospects of extractive fermentation systems. This review will also focus on the parameters responsible for better separation for in situ fermentation.

TL;DR: The diversity of KSB as bioinoculants to release potassium provides a win-win situation and it is crucial to adopt efficient KSB strain interventions for the judicious use of chemical and biological resources for maximizing food production while reducing pollution and rejuvenating degraded land for agricultural benefit.
Abstract: The present investigation comprises a total of fifty potassium solubilizing bacterial (KSB) strains which were isolated from Oryza sativa, Musa paradisiaca, Zea mays, Sorghum bicolor and Triticum aestivum L. These strains were evaluated for their ability to solubilize the fixed K from waste biotite (WB). On the basis of K-solublization, the seven most efficient KSB strains were evaluated for K-solublizing dynamics from the WB at 7, 14 and 21 DAI (days after incubation) on MAMs (Modified Solid Aleksandrov Medium). Further, these screened seven KSB strains were used for their morphological, physiological and molecular chacterization. The KSB strains Bacillus licheniformis BHU18 and Pseudomonas azotoformans BHU21 showed significantly higher K-solublization 7.22 and 6.03 µg mL −1 at 30 °C and pH 7.0, respectively. A significantely higher zone of solubilization significantly higher was recorded with Pseudomonas azotoformans BHU21 (3.61 cm). Bacillus licheniformis BHU18 produced significantly higher (~23 µg mL −1 ) concentrations of indole-3-acetic acid. The diversity of KSB as bioinoculants to release potassium provides a win-win situation. Therefore, it is crucial to adopt efficient KSB strain interventions for the judicious use of chemical and biological resources for maximizing food production while reducing pollution and rejuvenating degraded land for agricultural benefit.
