All eight geometric isomers of methyl 2,4,6-decatrienoate were synthesized from readily accessible starting materials by fully exploiting Wittig-type olefinations, and taking advantage of an easy separation of 2E and 2Z unsaturated esters. The aggregation pheromone of the brown-winged green bug, Plautia stali, methyl (E,E,Z)-2,4,6-decatrienoate (also a cross-attractant for the brown marmorated ...

In recent years, research into the efficacy of indoor air biofiltration mechanisms, notably living green walls, has become more prevalent. Whilst green walls are often utilised within the built environment for their biophilic effects, there is little evidence demonstrating the efficacy of active green wall biofiltration for the removal of volatile organic compounds (VOCs) at concentrations foun...

A new test for the detection of bacterial phosphatase activity has been devised. The test is performed using agar media containing both methyl green (MG) and phenolphthalein diphosphate (PDP); in these media phosphatase-producing strains grow deep-green-stained colonies whereas non-producing strains do not. A total of 739 different strains were tested, including 593 staphylococci, 95 micrococci...

1. The relative absorption spectrum of the pigments in their natural state in the photosynthetic bacterium Spirillum rubrum is given from 400 to 900 mmicro. The position of the absorption maxima in the live bacteria due to each of the pigments is: green pigment, 420, 590, 880; red pigment, 490, 510, 550. 2. The relative absorption spectrum of the green pigment in methyl alcohol has been determi...

The role of presynaptic metabotropic glutamate receptor (mGluR) on the interaction of red- and green-cone signals was investigated in luminosity-type horizontal cell (LHC) of isolated carp retina. It was found that a dim red background could enhance LHC's light response to green stimulus, and a dim green background was also able to increase the cell's response to red flash. Such mutual color en...

Advanced industrialization has caused an increase in the continuous discharge of hazardous effluents environment. This study evaluated potential laccase synthesized by Bacillus sp. NU2 to degrade five synthetic dyes. Sawdust, wheat bran and peels banana tangerine were utilized as carbon sources for bacterial growth production. The produced crude enzyme was purified homogeneity determine its mol...

N-methyl pyrrolidone (NMP) is a polar aprotic solvent that critical for the production of polyaramids. However, due to its reprotoxicity and pending REACH restrictions, benign alternative needed. A mixture N-butyl (NBP) ionic liquid [C8MIm][Cl] proposed as promising candidate replace NMP. This organic electrolyte solution provides green approach polyaramid synthesis.

We describe a method which may be useful for the selection of samples for the study of early fibrillation in human articular cartilage. Blocks of cartilage and bone were cut post-mortem from the medial tibial condyles of 29 male and 31 female subjects and the grade of fibrillation was assessed from sections. Contiguous, unfixed blocks of cartilage from the same surface were immersed in a soluti...

Handler, Bernheim, and Klein (1) have shown that the oxidation of the N-methyl derivatives of nL-methionine, m-leucine, nL-alanine, and DLhistidine by rat liver and kidney preparations is due to the presence of n-amino acid oxidase, and that the N-methyl derivatives of nr,-phenylalanine, nL-tryptophan, and m,-valine are not oxidized by these preparations. Blanchard, Green, Nocito, and Ratner (2...
