The aims of this work were to isolate microorganisms from vinasse (V) and black liquor (BL), by-products alcohol paper industries assess their potential as substrates produce biosurfactants. Thirty-nine microorganisms, 19 V (acidophilic, a1 a19) 20 BL (alkaliphilic, b1 b20) isolated. A high- throughput method was design set up for surface tension ( γ ) measurement. In the first screening, 15/39...

An L-shape is the union of a horizontal and a vertical segment with a common endpoint. These come in four rotations: L, L , Land L . A k-bend path is a simple path in the plane, whose direction changes k times from horizontal to vertical. If a graph admits an intersection representation in which every vertex is represented by an L, an L or L , a k-bend path, or a segment, then this graph is cal...

The lantibiotic nisin is produced by several strains of Lactococcus lactis. The complete gene cluster for nisin biosynthesis in L. lactis 6F3 comprises 15 kb of DNA. As described previously, the structural gene nisA is followed by the genes nisB, nisT, nisC, nisI, nisP, nisR, and nisK. Further analysis revealed three additional open reading frames, nisF, nisE, and nisG, adjacent to nisK. Approx...

The clinical, laboratory, and radiological features, including histocompatibility typing, of 28 patients with juvenile psoriatic arthritis are reported. The most common presentation was that of psoriasis preceding or occurring simultaneously with arthritis. The most common course of juvenile psoriatic arthritis was to start as an oligoarthritis and progress, usually to polyarthritis. No patient...

The insulin from the Atlantic hagfish (Myxine glutinosa) has been one of the most studied insulins from both a structural and a biological viewpoint; however, some aspects of its biology remain controversial, and there has been no satisfying structural explanation for its low biological potency. We have re-examined the receptor binding kinetics, as well as the metabolic and mitogenic properties...

12 The decrease in energy was not found to increase instrumental stray light significantly. The stray light characteristics of the instrument are discussed elsewhere., 3Jones, R. N., J. Am. Chem. Soc., 74, 2681 (1952). 14 A similar apparatus is described by J. Cunningham and F. C. Tompkins, Proc. Roy. Soc., A251, 27 (1959). 51 Simpson, W. T., and D. L. Peterson, J. Chem. Phys., 26, 588 (1957). ...

The physiological performance of a reef-building coral is a combined outcome of both the coral host and its algal endosymbionts, Symbiodinium While Orbicella annularis-a dominant reef-building coral in the Wider Caribbean-is known to be a flexible host in terms of the diversity of Symbiodinium types it can associate with, it is uncertain how this diversity varies across the Caribbean, and wheth...
