Characterization of form variants of Xenorhabdus luminescens.
From Xenorhabdus luminescens XE-87.3 four variants were isolated. One, which produced a red pigment and antibiotics, was luminescent, and could take up dye from culture media, was considered the primary form (XE-red). A pink-pigmented variant (XE-pink) differed from the primary form only in pigmentation and uptake of dye. Of the two other variants, one produced a yellow pigment and fewer antibi...
متن کاملXenorhabdus luminescens (DNA hybridization group 5) from human clinical specimens.
An unusual isolate from a human leg wound was identified as Xenorhabdus luminescens. This finding led to the discovery or isolation of four additional strains, two from blood and two from wounds. Three of the five strains were from patients in San Antonio, Tex. Three strains were studied by DNA-DNA hybridization (S1 nuclease-trichloroacetic acid method) and were 77 to 100% related to each other...

رابطه ی میانِ هنر و شرایطِ اجتماعیِ زایش آن همواره در طولِ تاریخ دغدغه ی ذهنی و دل مشغولیِ اساسیِ منتقدان و نیز هنرمندان بوده است. از آنجا که هنر در قفس آهنیِ زندگیِ اجتماعی محبوس است، گسترش وابستگیِ آن با نهاد ها و اصولِ اجتماعی پیرامون، صرفِ نظر از هم سو بودن و یا غیرِ هم سو بودنِ آن نهاد ها، امری اجتناب ناپذیر به نظر می رسد. با این وجود پدیدار گشتنِ چنین مباحثِ حائز اهمییتی در میان منتقدین، با ظهورِ مکتب ما...
Characterization of an Extracellular Protease from the Insect Pathogen Xenorhabdus luminescens.
Xenorhabdus luminescens Hm cultured in gelatin broth produced a single extracellular protease. The protease was purified by a factor of 500 and characterized as a monomeric protein with an approximate molecular weight of 61,000. On the basis of inhibitor studies and its pH optimum, the protease was classified as an alkaline metalloprotease with a pH optimum near 8; the isoelectric point of the ...
متن کاملMolecular cloning and characterization of the lux genes from the secondary form of Xenorhabdus luminescens, K122.
Xenorhahdus lurninescens is a luminous bacterium which is symbiotic with the entomopathogenic nematode Hererorhabdiris. The bacteria play an important role in pathogenesis of insect larvae. Once the nematode enters the larvae, Xennrhabdus spp are released from the gut of the nematode into the hemocoel of the insect. Here both the bacteria and the nematodes proliferate and kill the insect within...
