Sahay Ram Bose
Sahay Ram Bose ( bn, সহায়রাম বসু; 15 February 1888 – 1970) was an Indian botanist known for his pioneering work in the study of bracket fungi and the discovery of antibiotics Polysporin and Campestrin. In a research career spanning more than half a century, Bose published 120 papers on various aspects of fungi in an array of academic journals across Europe, America, and Asia. Bose is credited for pioneering work on mycology and the antibacterial properties of fungi. Biography Early years Sahay Ram Bose was born on 15 February 1888. Career Bose was Professor of Botany in Bangabasi College in 1909, and Carmichael Medical College in 1916. In 1918 he went to Ceylon (now Sri Lanka) on a deputation to the Royal Botanical Gardens, Perudeniya for training in systematic of Bengal Polyporaceae (bracket fungi) under the famous mycologist Tom Petch. Polyporaceae became the subject for his lifetime study. Bose published his findings in Polyporaceae of Bengal, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

Polyporin
Polyporic acid is a para- terphenyl benzoquinone compound first identified by German chemist Stahlschmidt from a mycelial culture of the fungus species ''Hapalopilus nidulans'' in 1877. This chemical, present at 20–40% of the fresh weight of the fruit bodies, inhibits the enzyme dihydroorotate dehydrogenase. It is found in other mushrooms, but in much lower amounts. In animal studies, consumption of polyporic acid caused reduced locomotor activity, depressed visual placing response, hepatorenal failure, metabolic acidosis, hypokalaemia, and hypocalcaemia. Because these effects are similar to those observed in individuals poisoned by ''H. nidulans'', polyporic acid is thought to be the primary toxin in ''H. nidulans''. Polyporic acid has some antifungal and antibacterial activity. It has been shown to be an intermediate in the biosynthesis of allantofuranone, a gamma-lactone Lactones are cyclic carboxylic esters, containing a 1-oxacycloalkan-2-one structure (), or analogue ...

Emperor Hirohito
Emperor , commonly known in English-speaking countries by his personal name , was the 124th emperor of Japan, ruling from 25 December 1926 until his death in 1989. Hirohito and his wife, Empress Kōjun, had two sons and five daughters; he was succeeded by his fifth child and eldest son, Akihito. By 1979, Hirohito was the only monarch in the world with the title "emperor". He was the longest-reigning historical Japanese emperor and one of the longest-reigning monarchs in the world. Hirohito was the head of state under the Meiji Constitution during Japan's imperial expansion, militarization, and involvement in World War II. Japan waged a war across Asia in the 1930s and 40s in the name of Hirohito, who was revered as a god. After Japan's surrender, he was not prosecuted for war crimes, as General Douglas MacArthur thought that an ostensibly cooperative emperor would help establish a peaceful Allied occupation, and help the U.S. achieve their postwar objectives.

Herbarium
A herbarium (plural: herbaria) is a collection of preserved plant specimens and associated data used for scientific study. The specimens may be whole plants or plant parts; these will usually be in dried form mounted on a sheet of paper (called ''exsiccatum'', plur. ''exsiccata'') but, depending upon the material, may also be stored in boxes or kept in alcohol or other preservative. The specimens in a herbarium are often used as reference material in describing plant taxa; some specimens may be types. The same term is often used in mycology to describe an equivalent collection of preserved fungi, otherwise known as a fungarium. A xylarium is a herbarium specialising in specimens of wood. The term hortorium (as in the Liberty Hyde Bailey Hortorium) has occasionally been applied to a herbarium specialising in preserving material of horticultural origin. History The making of herbaria is an ancient phenomenon, at least six centuries old, although the techniques have changed l ...
