isolation of bacteriophage from thermoactinomyces.bacteriophages were isolated from strains of thermoactinomyces vulgaris, t. candidus, and t. sacchari used to produce antigen for hypersensitivity pneumonitis screening at the marshfield medical foundation. whereas the one phage isolated from t. sacchari and two phages from t. vulgaris were species specific, three other phages isolated from t. vulgaris and the two phages isolated from t. candidus were infectious for both t. vulgaris and t. candidus, thus indicating a close relationship between t ...1977914995
studies on thermoactinomyces sp. tm9208. i. description of the strain.a strain of thermoactinomyces sp., tm9208, isolated from a soil sample in the taipei area showed antagonistic activity to gram positive bacteria but not to the gram negative on the potato extract agar plate by the cross streaking method. the strain showed strong starch hydrolysis, beta type of hemolysis, brownish yellow growth on the potato extract agar and green on the nutrient agar. its aerial mycelium, white to grayish white, was long and straight with short branches. the spores are single an ...1977578130
production of thermophilic actinomycete-hay aerosols for use in experimental hypersensitivity pneumonitis.an investigation of the factors that influence the production of dense aerosols of micropolyspora faeni and thermoactinomyces vulgaris from hay cultures revealed that the density, freshness, and moisture content of the hay were important influences. dry aerosols were produced under optimum conditions from hay cultures of either actinomycete and from sterile hay for inhalation challenges to unimmunized rabbits. depressions in arterial oxygen tensions and hemolytic complement were monitored after ...1977596873
[isolation, crystallization and partial characterization of a cationic protease from thermoactinomyces vulgaris].a simple method was developed for the isolation of the cationic endopeptidase from a crude extract prepared from the culture medium of thermoactinomy ces vulgaris, consisting in chromatography on sephadex g 75 and subsequent separation on cm-sephadex in 50 mm tris/hcl, ph 8, using a nacl-gradient (0 - 0,2 m). this procedure results in a 4,2 fold increase of the elastolytic activity (substrate: n-acetyl-(l-ala)3methyl ester) of the enzyme. it moves as a single band in sds-gel electrophoresis and ...1977612086
elimination of bagassosis in louisiana paper manufacturing plant workers.the prevalence of bagassosis was investigated in a louisiana paper mill, which in the past had considerable numbers of workers with the disease. based on negative clinical histories and the low number of positive serological reactions of the workers' serum with thermoactinomyces sacchari antigen, it was concluded that bagassosis was no longer present. this was thought to be due to a different method of storage of bagasse, which retards microbial decay and reduces airborne organic dust, and to th ...1978627039
[viability study of actinomycete cultures preserved for a long time on agar media].viability of 254 actinomycetous strains stored for 1 to 6 years on agarized media a temperature of 4-10 degrees c without passages was studied. the cultures included 204 strain of actinomyces, 26 strains of mycobacterium, 2 strains of streptosporangium, 1 strain of intrasporangium, 2 strains of micropolyspora and 5 strains of thermoactinomyces. most of the cultures, i.e. 94.55 per cent stored for 6 years remained vialbe after the this period. with an increase in the storage period from 1 to 4 ye ...1978655683
characterization of thermoactinomyces sacchari antigens.three different extracts of thermoactinomyces sacchari were analyzed for their antigenicity and physical-chemical properties. rabbit antiserum to each preparation, tested by immunodiffusion in gel, demonstrated that the most potent immunogen was that prepared by the double-dialysis method. this extract also contained the greatest number of precipitating antigens as detected by gel filtration. all extracts, analyzed by column chromatography on sephadex g-75, were heterogeneous in that they contai ...1978669809

[substrate specificity of a protease from thermoactinomyces vulgaris].the cleavage specificity of a protease from thermoactinomyces vulgaris (thermitase) was determined by the insulin b-chain and the cleavability of casein and haemoglobin by this enzyme as compared to other proteases (trypsin, chymotrypsin, proteases from bac. megaterium and cytophages). the most intense splitting effect on the substrates under investigation (insulin b-chain, casein and haemoglobin) is exerted by thermitase, i. e., the unspecificity of this enzyme is especially marked.1979460396
properties of thermoactinomyces vulgaris phage ta1 and its extracted dna.the virulent phage ta1 was obtained in good yields from infected cultures of thermoactinomyces vulgaris 1227. the purified phage was found to sediment with a single band, the sedimentation constant being (519 +/- 14)s, and to exhibit a typical nucleoprotein behaviour in uv-spectrophotometric and cd experiments. the ta1 phage consists of a hexagonal head about 0.056 micrometers in diameter and a very short tail. it is morphologically similar to the temperate salmonella phage p22. the nucleic acid ...1979516794
crossed immunoelectrophoretic analysis of two antigen extracts of thermoactinomyces candidus.a pyridine extract antigen and a double-dialysis antigen (dda) obtained from thermoactinomyces candidus were analyzed by crossed immunoelectrophoresis. in addition, the heat lability, pronase sensitivity, and isolectric points of the components of the dda were determined. by using antisera raised against crude pyridine extract antigen, two immunogenic components were resolved by crossed immunoelectrophoresis. a similar analysis of dda using antisera raised against crude dda revealed 15 immunogen ...1979528048
[lipolytic activity from milk isolated strains of the species thermoactinomyces vulgaris, tsiklinsky 1899 (author's transl)].thirty strains of the species thermoactinomyces vulgaris (tsiklinsky, 1988) were isolated from milk and tested for their lipolythic activity. after incubation for 120 hours at 55 degrees c they formed distinct diffusion zones on culture media containing tributyrin and tween-80. in all strains exocellular lipases were found. their action on the milk fat increased the number of the free fatty acids. triglycerides, free fatty acids as well as diglycerides and monoglycerides were identified as split ...1979573533
phosphate utilization and constitutive synthesis of phosphatases in thermoactinomyces vulgaris tsilinsky.thermoactinomyces vulgaris utilized both organic and inorganic phosphates with equal efficiency for its growth. the specific activities of the thermophilic acid and alkaline phosphatases were found to be maximum at 1 mm concentration of each phosphate source. all the phosphatase isoenzymes (three alkaline and one acidic) were observed irrespective of the substrate source and concentration, suggesting constitutive synthesis of the enzymes. during growth and differentiation, both acid and alkaline ...19806258569
respiratory symptoms and lung function in a sample of vermont dairymen and industrial workers.this study reviews the respiratory status of a sample of vermont male dairy farmers, and a comparison group from industry, matched for age, sex and smoking. survey instruments included a standardized questionnaire and simple pulmonary function tests. in general, past and present smokers had more respiratory symptoms than never-smokers; and farmers, in all smoking categories, reported symptoms with greater frequency than did their counterparts from industry. forced vital capacity (fvc) tended to ...19807356085
