1,3-Propanediol, a valuable bifunctional molecule, can be produced from renewable resources using microorganisms. It has several promising properties for many synthetic reactions, particularly for polymer and cosmetic industries. By virtue of being a natural product, relevant biochemical pathways can be harnessed into fermentation processes to produce 1,3-propanediol. Various strategies for the...

We report the complete genome sequence of Lactobacillus plantarum CGMCC 8198, a novel probiotic strain isolated from fermented herbage. We have determined the complete genome sequence of strain L. plantarum CGMCC 8198, which consists of genes that are likely to be involved in dairy fermentation and that have probiotic qualities.

Commercial application of many promising heterocyclic natural products is limited by their natural abundance. While organic synthesis provides access to many natural products, total synthesis of numerous complex molecules is not economically feasible. In recent years, the combination of fermentation and organic synthesis has provided a new route for the production of complex heterocycles that a...

Honey is a natural product with recognized physical and chemical properties, which contribute to its biological activity. However, honey is currently being sold at low prices, making it imperative to find alternatives to make apiculture a viable national enterprise. One of these alternatives could be mead production. Despite the excellent properties of honey, mead production faces several probl...

A novel type of anaerobic bacteria was previously isolated from profundal lake sediment by direct dilution of the sediment in mineral agar medium containing glucose and a background lawn of Methanospirillum hungatei as a syntrophic partner. The isolated bacteria grouped with aerobic Bacillus spp. according to their 16S rRNA gene sequence, and the most closely related species is Bacillus thiopar...

It is well recognized that products other than lactic acid may be produced by homofermentative lactic acid-producing streptococci. Small quantities of formic, acetic, propionic, and butyric acids, ethanol, carbon dioxide, 2,3-butanediol, acetoin, and biacetyl have been reported as metabolic products of these organisms (Hammer, 1920; Foster, 1921; Langwill, 1924; Long and Hammer, 1936). Of these...

Solid state fermentation (SSF) technology has been widely used in the industry over the last three decades. The advantages of SSF processes attract the researchers and industrialists to pay attention onto this system than the other fermentation systems even though there are some concerns in this system such as: problem in scale-up, higher requirement for controlling process, unavailability of d...

A great deal of research has been performed on the acetone and butyl alcohol fermentation of maize, potatoes, horse-chestnuts, and other cereals rich in starch, in which various organisms of t’he widely distributed Granulobacter type have been employed. No systematic investigation has been made, however, of the action of this type of organism on other carbohydrates; namely, the various sugars. ...

Eight fermentative bacterial strains were isolated from mixed enrichment cultures of a composite soil sample collected at 1.34 km depth from the former Homestake gold mine in Lead, SD, USA. Phylogenetic analysis of their 16S rRNA gene sequences revealed that these isolates were affiliated with the phylum Firmicutes belonging to genera Bacillus and Clostridium. Batch fermentation studies demonst...

Recent studies using germ-free, gnotobiotic microbial transplantation/conventionalization or antibiotic treatment in rodent models have highlighted the critical role of intestinal microbes on gut health and metabolic functions of the host. Genetic and environmental factors influence the abundance and type of mutualistic vs. pathogenic bacteria, each of which has preferred substrates for growth ...
