The present invention addresses to the production of an organomineral fertilizer consisting of a mineral matrix, drilling gravel and an organic matrix, algae biomass. Algae are cultivated using drilling gravel suspended in the culture medium together with their ability to grow by absorbing CO.sub.2, and, in the case of cyanobacteria, they fix atmospheric nitrogen in their biomass. The gravel provides a set of additional nutrients present in its composition to the conventional nutritional chemical compounds for algae. In this way, the gravel can be mixed with the culture medium in the cultivation of algae, generating the organic matrix to be formulated and commercialized in the national and international agricultural market as an organomineral fertilizer, and, in the case originating from the organic matrix of cyanobacteria, there is the enrichment with nitrogen obtained biologically, without the high energy expenditure typical of traditional synthetic nitrogen fertilizers. In this way, the present invention enables the disposal with a minimum of environmental impact and constitutes a satisfactory solution for the disposal of gravel for oil E&P.

An agricultural or horticultural fertilizer, and method of making the fertilizer, featuring processed montmorillonite clay and other ingredients for improving plant growth and health. Liquid fertilizers for use in drip irrigation may comprise potash in an aqueous blend, as well as citric acid and humate. The method involves the preparation of a montmorillonite mineral-humate solution, which solution is mixed with other ingredients. In an early step, the montmorillonite and the humate are mixed with water and citric acid, and then blended or mixed over a period of time sufficient for the citric acid to leach the montmorillonite and humate into solution. The solution is then filtered to remove solid mineral residue. The filtered solution is then mixed with Aloe vera and potash to prepare a concentrated liquid.

There is provided an apparatus for extraction of at least one object from a cavity. The apparatus includes a sleeve including an inflatable section configured to surround the at least one object during inflation; a handle configured to enable a user to hold the sleeve, the handle defining a holding edge of an opening at a first portion of the sleeve; and a handle-mount mounted to a peripheral area around the opening, the handle-mount being for attachment of a pump used for inflating the inflatable section. There is also provided a pressure limitation apparatus configured to operate with a birth assistance device when attached via a conduit.

Described herein are anti-microbial and UV-protective biological devices and extracts produced therefrom. The biological devices include microbial cells transformed with a DNA construct containing genes for producing proteins such as, for example, zinc-related protein/oxidase, silicatein, silaffin, and alcohol dehydrogenase. In some instances, the biological devices also include a gene for lipase. Methods for producing and using the devices are also described herein. Finally, compositions and methods for using the devices and extracts to kill microbial species or prevent microbial growth and to reduce or prevent UV-induced damage or exposure to materials, items, plants, and human and animal subjects are described herein. Also disclosed are biological devices producing polyactive carbohydrates and carbo sugars, as well as compositions and articles incorporating both extracts from these devices and the anti-microbial and UV-protective extracts.

The invention provides compositions and systems comprising a carrier and an element. The carrier is a network of polymers insoluble in water comprising phenolic hydroxyl moieties, aliphatic hydroxyl moieties or a combination thereof. An association between the carrier and the element is labile in response to biological demand and the lability of the association in the presence of water is less than the lability of the association in response to biological demand. Also provided are methods of making such compositions and methods for delivering the element to an organism.

A combined microalgae and mycorrhizal fungi granular formulation includes a microalgae inoculant combined with a mycorrhizal fungi inoculant with demineralized water to maintain moisture and applied to carrier granules such as a natural clay-based or mineral-based material. The coated granules are dried and may be applied to agricultural areas in dried granular form.
