Impact of PGPR inoculation on photosynthetic pigment and protein contents in Arachis hypogaea L.

The impact of microbial consortium comprising plant development advancing rhizobacteria (PGPR) like Rhizobium, Pseudomonas and Bacillus were tried independently and in blend of Arachis hypogaea. The mixes of previously mentioned PGPR strains essentially expanded photosynthetic color (chlorophyll an and b, add up to chlorophyll and carotenoid) and protein content in A. hypogaea, when contrasted with the un-inoculated control. The consequences of this study propose that PGPR connected in mix can possibly build the photosynthetic colors and protein substance of A. hypogaea which can be a potential tool in increasing the yield in this economically important crop in sustainable way.

Studies on the origin of the sticky coat on the eggs of the nematode Thelastoma bulhõesi (Magalhães, 1900)

1. The eggs of Thelastoma bulhõesi are shown to have a sticky outer coat of acid mucopolysaccharide.2. The acid mucopolysaccharide is secreted by the lower uterus wall and by the vagina uterina.3. A protein substance of unknown function has been observed in invaginations in the ovijector of T. bulhõesi.4. This protein substance appears to be secreted by the lower part of the vagina uterina and passed along into the ovijector.5. Possible functions of the mucopolysaccharide coat on the eggs, and of the protein substance in the ovijector, are discussed.I wish to express my thanks to Dr P. Tate for many invaluable suggestions and for his constant encouragement during this investigation.

Variation in Agglutinin Formation in Mental Hospital Patients and Its Probable Relation to Focal Sepsis

It is well known that injection of protein substance into the blood causes the appearance in the blood of antibodies to the protein. Injection of bacteria is followed by the appearance of several kinds of antibodies, and the substances which produce “clumping” constitute one, or rather two, of these antibodies. The appearance of agglutinins in the blood following vaccination or infection has been shown to occur regularly in such a large number of individuals, and in animals, that there can be no doubt that this production of antibodies is a natural phenomenon connected with successful resistance to the deleterious effects of the organisms. Non-production or abnormalities in the production of agglutinins following injection of bacteria represents a pathological process probably of the nature of sepsis.

ON PRECIPITABLE SUBSTANCES DERIVED FROM BACILLUS TYPHOSUS AND BACILLUS PARATYPHOSUS B

Attempts to confirm certain statements that ether-soluble specific substances can be obtained from B. typhosus have lead to negative results. Two serologically active protein substances and another that was non-protein have been separated from B. typhosus. The first two are not resistant to tryptic digestion or to treatment with alkaline hypochlorite solution whereas the third resists both. One of the proteins could be extracted with 75 per cent alcohol. Specific precipitable substances reacting like the non-protein substance of B. typhosus and containing large amounts of carbohydrates have been prepared from B. paratyphosus B, B. enteritidis, and Proteus HX19 and OX19. Observations on the serological behaviour of these preparations are described.

To the technique of studying the structure of bacteria

The author found that such microbes as diphtheria, typhoid and anthrax bacilli have clearly differentiated nuclei. The latter, however, are mostly invisible due to the presence in the bacterial cell of a protein substance (deutoplasm), which has the ability to perceive coloring particularly well; surrounding the nucleus on all sides, this substance makes it invisible.
