Bromoform was discovered in 1832 by Löwig who distilled a mixture of bromal and potassium hydroxide, as analogous to preparation of chloroform from chloral. [5]Bromoform can be prepared by the haloform reaction using acetone and sodium hypobromite, by the electrolysis of potassium bromide in ethanol, or by treating chloroform with aluminium bromide.
Many plants, such as peanuts, produce compounds that are only dangerous to people who have developed an allergic reaction to them, and with a few exceptions, those plants are not included here (see list of allergens instead). Despite the wide variety of plants considered poisonous, human fatalities caused by poisonous plants – especially ...
Spraying antibiotics such as streptomycin and organic bactericides is another way to control P. syringae but is less common than the methods listed above. [29] New research has shown that adding ammonium (NH 4 +) nutrition to tomato plants can cause a metabolic change leading to resistance against Pseudomonas syringae.
Pseudomonas infection refers to a disease caused by one of the species of the genus Pseudomonas. P. aeruginosa is a germ found in the environment and it is an opportunistic human pathogen most commonly infecting immunocompromised patients, such as those with cancer , diabetes , cystic fibrosis , [ 1 ] severe burns, AIDS , [ 2 ] or people who ...
Phytoncides are antimicrobial allelochemic [dubious – discuss] volatile organic compounds derived from plants.The word, which means "exterminated by the plant" [citation needed] (from the Greek φυτόν "plant" and the Latin caedere "to kill"), was coined in 1928 by Boris P. Tokin, a Soviet biochemist then studying at Moscow State University. [1]
They are also the source of many antibiotics. [9] [10] The Actinomycetota genus Bifidobacterium is the most common bacteria in the microbiome of human infants. [11] Although adults have fewer bifidobacteria, intestinal bifidobacteria help maintain the mucosal barrier and reduce lipopolysaccharide in the intestine. [12]
References to diseases now known to be caused by phytoplasmas can be found as far back as 1603 (mulberry dwarf disease in Japan). [4]Such diseases were originally thought to be caused by viruses, which, like phytoplasmas, require insect vectors and cannot be cultured.
Alternaria is a genus of Deuteromycetes fungi. All species are known as major plant pathogens.They are also common allergens in humans, growing indoors and causing hay fever or hypersensitivity reactions that sometimes lead to asthma.
