Macromolecular Insect Chitinase Inhibitors Produced by Fungi: Screening and Partial Characterization
insect chitinase inhibitor insect growth regulator Spodoptera litura static culture
2009/3/7
Culture broths of fungal strains were screened for novel insect chitinase inhibitors using the Spodoptera litura chitinase inhibitory assay. The culture filtrates of 5 strains showed potent and spec...
Nitrosomonas europaea ATCC25978 Is the Right Ammonia-Oxidizing Bacterium for Screening Nitrification Inhibitors
ammonia-oxidizing bacteria susceptibility to nitrification inhibitors nitrapyrin
2009/3/6
To determine whether Nitrosomonas europaea is adequate to assay nitrification inhibitors as representative of ammonia-oxidizing bacteria or not, the inhibitory activity exhibited by known nitrificat...
Screening and partial characterization of inhibitors of insect β-N-acetylglucosaminidase
chitin metabolic turnover chitinolytic enzyme system enzyme inhibitor insect growth regulator (IGR) microbial metabolite β-N-acetylhexosaminidase (EC 3.2.1.30)
2009/3/5
Microbial culture broths were screened for novel β-N-acetylglucosaminidase (GlcNAcase) inhibitors specific for the enzyme of insect origin. Four strains of actinomycetes, Streptomyces griseoloalbus ...
Environmental distribution and novel high-throughput screening of APEO-degrading bacteria using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry（MALDI-MS）
alkylphenol polyethoxylate (APEO) APEO-degrading bacteria MALDI- MS typing by MALDI-MS
2009/3/5
Fifteen soil samples from the edge of a creek were investigated for alkylphenol polyethoxylate (APEO) degrading ability. Ten soil samples possessed PEG chain shortening activity and the other soil s...
Screening of Winter Barley Varieties (Hordeum vulgare) for Resistance against Loose Smut (Ustilago nuda) and Covered Smut (Ustilago hordei) in Germany
winter barley loose smu covered smut resistance
2014/3/13
Because of the interdiction of chemical seed treatment in organic farming, resistance is a main demand
for organic seed production. Only little was known about the resistance of winter barley agains...
