    Notes: [Auszug] The New Zealand experiment was made on 3 Corriedale ewes with 3 control animals. Lighting for the experimental group was by incandescent light and for the control group by indoor daylight. The Australian experiment used 7 Southdown ewes in both experimental and control groups and the lighting was ...

    Notes: [Auszug] THE influence of climate on the annual rhythm JL of wool growth has puzzled physiologists for many years. We have discussed the earlier literature elsewhere1, and since our review Hart2 has given more details of his work on the effects of day-length. Recently, Morris8 reported experiments from ...

    Notes: Abstract In a new golden age, polyketides are investigated and manipulated with the tools of molecular biology and genetics; hybrid polyketides can be produced. Pharmaceutical companies hope to find new and useful polyketide products, including antibiotics, anthelminthics, and immunosuppressants. This review describes the past developments (largely chemical) on which the present investigations are based, attempts to make sense of the expanding scope of polyketides, looks at the shifting research focus around polyketides, presents a working definition in biosynthetic terms, and takes note of recent work in combinatorial biosynthesis. Also discussed is the failure of the classical enzymological approach to polyketide biosynthesis.

    Notes: We have optically written persistent but erasable metallic features in insulating epilayers of AlxGa1−xAs doped with Si and Se, which form DX centers. The photocarriers, which remain in the AlxGa1−xAs layer, move freely in the conduction band but are confined to the exposed regions. We demonstrate this confinement by optical excitation in a striped pattern; the resulting modulation of the free carrier density is evinced by an anisotropy of the sample conductance parallel and perpendicular to the stripes. The anisotropy, like the photoconductivity itself, is persistent at low temperatures. Erasure is achieved by thermal annealing. We estimate that features can be written with better than 1000 A(ring) resolution. © 1994 American Institue of Physics.

    Notes: Transport measurements on large single crystals of Cd0.8Zn0.2Te:Cl indicate that Cl donors form DX centers in CdZnTe. We have observed persistent photoconductivity (PPC) with an annealing temperature Ta≈130 K. Hall-effect experiments indicate that the PPC arises from a persistent increase in the density of charge carriers; the saturation density is Nsat=6×1016 cm−3. The deep binding energy of the DX center is Ed=0.22 eV. © 1995 American Institute of Physics.

    Notes: Room temperature giant magnetoresistance (GMR) has been measured in small band-gap thin-film Hg1−xCdxTe (x∼0.1) samples with Corbino disk electrode configurations. The GMR exhibits a zero-field offset of as much as 350 G at room temperature. The resultant asymmetry in the field dependence of the GMR constitutes a self-biasing effect. We show that this self-biasing results from spatial composition fluctuations in the sample and that the bias effect can be controlled by selective doping and/or deposition masking. © 1996 American Institute of Physics.

    Notes: Secondary metabolism is the biosynthesis, transformation, and degradation of a wide array of natural products. These low molecular weight organic compounds are generally produced at a restricted phase of the life cycle, often in association with differentiated morphological structures. No unified theory to explain the function of secondary metabolism in the producing organism has been accepted, however one hypothesis that has received widespread attention views secondary metabolites as initiatiors or coordinators of spore formation. A review of the literature indicates that there is ample experimental evidence to nullify this hypothesis. Although secondary metabolite production is often correlated with morphological differentiation, it is not the cause of it. Cellular and chemical differentiation can both be comprehended as different aspects of biological diversification, mediated by Darwinian evolutionary forces.

    Notes: Benzo[a]pyrene (B[a]P) is a carcinogenic polyaromatic hydrocarbon that enters the environment as an incomplete combustion production of fossil fuels. Several species of filamentous fungi are capable of biotransforming and/or mineralizing B[a]P in liquid cultures, however there has been less success in soil habitats. In this study, the litter rot fungus Marasmiellus troyanus was encapsulated in alginate and delivered to B[a]P-spiked soil microcosms (100 μg B[a]P/g soil) for 1, 2 and 6 weeks, with and without a fertilizer solution. After 2 weeks, 32.5% of B[a]P was recovered from soil microcosms treated with M. troyanus compared to 55–70% for controls. After 6 weeks, controls demonstrated an average percent recovery of B[a]P of 54% while M. troyanus-inoculated samples gave an average percent recovery of 11%. Similar bioaugmentation of contaminated habitats with appropriately formulated fungi has potential for practical bioremediation in soil environments. Journal of Industrial Microbiology & Biotechnology (2000) 25, 116–119.
