Lactobacillus is a genus of gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non-spore-forming bacteria. Until 2020, the genus Lactobacillus comprised over 260 phylogenetically, ecologically, and metabolically diverse species; a taxonomic revision of the genus assigned lactobacilli to 25 genera.
Myristicin is a naturally occurring compound found in common herbs and spices, such as nutmeg. It is an insecticide, and has been shown to enhance the effectiveness of other insecticides.
A natural product is a natural compound or substance produced by a living organism—that is, found in nature. In the broadest sense, natural products include any substance produced by life. Natural products can also be prepared by chemical synthesis and have played a central role in the development of the field of organic chemistry by providing challenging synthetic targets. The term natural product has also been extended for commercial purposes to refer to cosmetics, dietary supplements, and foods produced from natural sources without added artificial ingredients.
Aspergillus fumigatus is a species of fungus in the genus Aspergillus, and is one of the most common Aspergillus species to cause disease in individuals with an immunodeficiency.
Tolypocladium inflatum is an ascomycete fungus originally isolated from a Norwegian soil sample that, under certain conditions, produces the immunosuppressant drug ciclosporin. In its sexual stage (teleomorph) it is a parasite on scarab beetles. It forms a small, compound ascocarp that arises from the cadaver of its host beetle. In its asexual stage (anamorph) it is a white mold that grows on soil. It is much more commonly found in its asexual stage and this is the stage that was originally given the name Tolypocladium inflatum.
Gliotoxin is a sulfur-containing mycotoxin that belongs to a class of naturally occurring 2,5-diketopiperazines produced by several species of fungi, especially those of marine origin. It is the most prominent member of the epipolythiopiperazines, a large class of natural products featuring a diketopiperazine with di- or polysulfide linkage. These highly bioactive compounds have been the subject of numerous studies aimed at new therapeutics. Gliotoxin was originally isolated from Gliocladium fimbriatum, and was named accordingly. It is an epipolythiodioxopiperazine metabolite that is one of the most abundantly produced metabolites in human invasive Aspergillosis (IA).
Ribose-phosphate diphosphokinase is an enzyme that converts ribose 5-phosphate into phosphoribosyl pyrophosphate (PRPP). It is classified under EC 2.7.6.1.
Mucor racemosus is a rapidly growing, weedy mould belonging to the division Mucoromycota. It is one of the earliest fungi to be grown in pure culture and was first isolated in 1886. It has a worldwide distribution and colonizes many habitats such as vegetational products, soil and houses. The fungus is mostly known for its ability to exhibit both filamentous and yeast-like morphologies, often referred to as dimorphism. Stark differences are seen in both forms and conditions of the environment heavily affect the phases of the M. racemosus. Like many fungi, it also reproduces both sexually and asexually. The dimorphic capacity of this species has been proposed as an important factor in its pathogenicity and has enhanced the industrial importance. This species is considered an opportunistic pathogen, generally limited to immunocompromised individuals. It also been associated with allergy and inflammations of facial sinuses. Its association with allergy has made it a common fungus used in allergen medical testing. Industrial use of the fungus is in the production of enzymes and the manufacture of certain dairy foods.
CD99 antigen, also known as MIC2 or single-chain type-1 glycoprotein, is a heavily O-glycosylated transmembrane protein that is encoded by the CD99 gene in humans. The protein has a mass of 32 kD. Unusually for a gene present on the X chromosome, the CD99 gene does not undergo X inactivation, and it was the first such pseudoautosomal gene to be discovered in humans.
Leukotriene B4 receptor 2, also known as BLT2, BLT2 receptor, and BLTR2, is an Integral membrane protein that is encoded by the LTB4R2 gene in humans and the Ltbr2 gene in mice.
Zaragozic acids are a family of natural products produced by fungi. The first characterized zaragozic acids, A, B, and C were isolated from an unidentified sterile fungal culture, Sporormiella intermedia, and L. elatius, respectively. just outside the European city Zaragoza, Spain on the Jalón river. This family of natural products possesses a unique 4,8-dioxabicyclo[3.2.1]octane core, and vary in their 1-alkyl and their 6-acyl side chains.
A depside is a type of polyphenolic compound composed of two or more monocyclic aromatic units linked by an ester group. Depsides are most often found in lichens, but have also been isolated from higher plants, including species of the Ericaceae, Lamiaceae, Papaveraceae and Myrtaceae.
Clavams are a class of antibiotics. This antibiotic is derived from Streptomyces clavuligerus NRRL 3585. Clavam is produced to form a new β-lactam antibiotic. This class is divided into the clavulanic acid class and the 5S clavams class. Clavulanic acid is a broad-spectrum antibiotic and 5S clavams may have anti-fungal properties. They are similar to penams, but with an oxygen substituted for the sulfur. Thus, they are also known as oxapenams.
Altechromone A is a chromone derivative. To date, it has been isolated from plant families such as Polygonaceae, Lamiaceae, Fabaceae, and Hypericaceae.

Gintonin is a glycolipoprotein fraction isolated from ginseng. The non-saponin ingredient was designated as gintonin, where gin was derived from ginseng, ton from the tonic effects of ginseng, and in from protein. The main component of gintonin is a complex of lysophosphatidic acids (LPA) and ginseng proteins such as ginseng major latex-like protein151 (GLP151) and ginseng ribonuclease-like storage protein.
Chrysophanol, also known as chrysophanic acid, is a fungal isolate and a natural anthraquinone. It is a C-3 methyl substituted chrysazin of the trihydroxyanthraquinone family.
Salinispora is a genus of obligately aerobic, gram-positive, non-acid-fast bacteria belonging to the family of Micromonosporaceae. They are heterotrophic, non-motile, and obligately grow under high osmotic/ionic-strength conditions. They are the first identified genus of gram-positive bacteria which has a high osmotic/ionic-strength requirement for survival. They are widely abundant in tropical marine sediments and were first identified in 2002. This genus of bacteria has potential biotechnological significance due to their production of novel secondary metabolites which can be used pharmaceutically.
Medicinal fungi are fungi that contain metabolites or can be induced to produce metabolites through biotechnology to develop prescription drugs. Compounds successfully developed into drugs or under research include antibiotics, anti-cancer drugs, cholesterol and ergosterol synthesis inhibitors, psychotropic drugs, immunosuppressants and fungicides.
Violacein is a naturally-occurring bis-indole pigment with antibiotic properties. Violacein is produced by several species of bacteria, including Chromobacterium violaceum, and gives these organisms their striking purple hues. Violacein shows increasing commercially interesting uses, especially for industrial applications in cosmetics, medicines and fabrics.
Didesmethylsibutramine (BTS-54524) is an active metabolite of the anorectic drug sibutramine that has been identified as an adulterant in weight loss supplements. Data on the activity of didesmethylsibutramine in humans is limited, although a case of psychosis associated with didesmethylsibutramine use was reported in 2019.
