[0120] Preparation of Microbial Based Products

[0121] A microorganism-based product of the present invention is simply a fermentation broth comprising the microorganisms and / or microbial metabolites and / or any residual nutrients produced by the microorganisms. Fermentation products can be used directly without extraction or purification. Extraction and purification can be readily achieved, if desired, using standard extraction and / or purification methods or techniques described in the literature.

[0122] The microorganisms in the microorganism-based product can be in active or inactive form. Microbial-based products may contain a combination of viable and non-viable microorganisms.

[0123] Microorganisms, microbial growth by-products, and / or broth produced from microbial growth can be removed from the growth vessel and transferred, for example, by piping for immediate use.

[0124] In other embodiments, the composition (microorganisms, metabolites, and / or culture broth)...

Embodiment 1

[0171] Embodiment 1: Sophorolipid fermentation

[0172] For the present invention, a natural mixture of sophorolipids was synthesized by fermenting Candida globosa in a fermentation medium containing 100 grams of glucose, 5 grams of yeast extract, 1 gram of urea and 100 grams of canola oil in 1000 ml of water. After 5-7 days of fermentation, the sophorolipids were collected by precipitation. After adding an additional amount of the same nutrient medium, the fermentation was continued for 3 days, after which another portion of SLP was collected.

[0173] Two different products were produced from this fermentation: one containing pure SLP and one containing a culture of Candida sphaeroides containing SLP.

Embodiment 2

[0174] Example 2: Preparation of SLP solution for foliar treatment

[0175] Precipitated SLP obtained by fermentation of Candida globosa can be used to produce products for the treatment of various types of versicolor virus in plants. Precipitated SLP typically contains no more than 50% water; however, such therapeutic products can be prepared without further concentration. The therapeutic product contains 0.1 to 0.5% (v / v) unpurified SLP.

Abstract

Compositions and methods are provided for treating certain plant pathogens using microbe-based products. In particular, the subject invention relates to treatment of plant pathogenic viruses, including mosaic virus, as well as plant pathogenic bacteria, using beneficial microbes and / or their growth by-products. In certain embodiments, the growth by-products are biosurfactants.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 564,517, filed September 28, 2017, which is hereby incorporated by reference in its entirety. Background technique [0003] Versicolor viruses are a group of plant pathogens that affect more than 150 different types of plants and can cause significant damage to them. Millions of growers have had some or all of their crops destroyed by the mosaic virus. The most common crop plants that can be infected by versicolor virus include potatoes, gourds, okra, peppers, cucumbers, melons, squash, tomatoes, tobacco, roses, tulips, beets, plums, beans, and many others. [0004] Several viruses belong to the "mosaic" disease, each belonging to one of several genera, for example, Begomovirus (e.g., cassava mosaic virus), Potyvirus (eg, pox virus), Tobamovirus (eg, tobacco mosaic virus), etc., and many other genera. Examples of mottle virus species inc...
