Culture media design and scaling-up of submerged fermentation for the nematophagous fungus Duddingtonia flagrans.

Biological control, which utilizes nematophagous fungi to reduce gastrointestinal nematode populations, may effectively diminish the need for chemical anthelmintic treatments. However, the limited knowledge surrounding the mass production of chlamydospores hinders the widespread use of biological products as alternatives to traditional anthelmintics. This study aimed to evaluate the development of liquid culture media for the large-scale production of the nematophagous fungi Duddingtonia flagrans using a systematic procedure, progressing from microplates to bioreactor.

Nematode predatory ability of the fungus Duddingtonia flagrans affected by in vitro sequential exposure to ovine gastrointestinal tract.

Duddingtonia flagrans is a nematophagous fungus employed as a biocontrol agent of gastrointestinal nematodes in ruminants. After oral ingestion and passage through the digestive tract of animals, this microorganism captures the nematodes in the feces. The drastic conditions of ruminant digestive tract could affect fungi chlamydospores and therefore biocontrol activity.

Trichoderma koningiopsis Survival on Coated Seeds and Effect on Plant Growth Promotion in Rice (Oryza sativa).

Seed coating is an alternative delivery system for beneficial plant microorganisms into the soil. Although seed coats are widely used for the application of agrochemicals, the incorporation of beneficial microorganisms has not been explored deeply and their survival on seeds while in storage is unknown. The study aimed to evaluate the effect of the coating process on microbial survival and on plant growth promotion.

In vitro evaluation of physicochemical variables on the nematophagous fungus Duddingtonia flagrans.

Duddingtonia flagrans is a biological alternative to the use of anthelmintic drugs in ruminants. This fungus must be ingested by the animal, pass through the cavities of the digestive tract and reach the feces where it develops traps that capture the nematodes. The severe conditions encountered in this process negatively affect the fungus, which is reflected in the low recovery rates compared to the amount administered.

Seed coating as a delivery system for the endophyte Trichoderma koningiopsis Th003 in rice (Oryza sativa).

Seed coating is a technique to cover seeds with external agents to upgrade their performance, handling, and plant establishment. Plant beneficial microbes (PBMs), such as plant growth-promoting bacteria, mycorrhizal fungi, and other fungi (e.g.

Effects of lipid formulations on clove extract spray dried powders: comparison of physicochemical properties, storage stability and in vitro intestinal permeation.

Clove is an aromatic plant spice with potent antioxidant and anti-inflammatory activity. Eugenol is the main compound which contributes to such medicinal and nutritional benefits. To date, the formulation of unstable, volatile and poorly water-soluble compounds remains a challenging task.

Clove (Syzygium aromaticum): a precious spice.

Clove (Syzygium aromaticum) is one of the most valuable spices that has been used for centuries as food preservative and for many medicinal purposes. Clove is native of Indonesia but nowadays is cultured in several parts of the world including Brazil in the state of Bahia. This plant represents one of the richest source of phenolic compounds such as eugenol, eugenol acetate and gallic acid and posses great potential for pharmaceutical, cosmetic, food and agricultural applications.
