example 1

[0095] This example is an offshore situation with the aim of disintegrating crude oil derived from an oil spill.

[0096] like Figure 1-4 As shown, the only apparatus required for the practice of the present invention, such as making and using the composition of the present invention at sea, is a mother ship containing a mixture 1 of petroleum and seawater, which can easily pass through a given mixture. Pump oil 2 and seawater into a storage tank of the mother ship.

[0097] In the next step, a source of phosphorus and nitrogen 3 (including hydrophobic fibers to reduce the density and provide buoyancy of the final product), a source of oxygen and / or an oxidizing agent 4 and a batch of microbial starter 5 Add the mixture 1 of the petroleum and seawater. This liquid premix is ​​left for a time range of 6-18 hours to provide a concentrated culture of the microorganisms.

[0098] Next, the liquid premix is ​​transferred to a smaller vessel with a storage tank that provides for ...

Embodiment approach

[0103] One embodiment is as follows:

[0104] The composition comprises the following components: a mixture of microbial strains, an oxygen supplier (SORA=Slow Release Oxygen Agent), a common matrix (fishmeal), an immobilization component (biopolymer) and a floating agent.

[0105] In more detail, 1 liter of a liquid solution of sodium alginate (3.0% w / v) was provided. This solution is added with 37 grams of calcium peroxide, 12 grams of fish meal, 40 grams of dry microorganisms (1x10 9 cells / gram) and 20 grams of coconut fiber, and thoroughly stirred to become a suspension, thus forming a premix. Described dry microorganism comprises following bacterial classification:

[0106] Pseudomonas stutzeri

[0107] Arthrobacter globiformis

[0108] Arthrobacter citreus

[0109] Bacillus pasteurii

[0110] Bacillus subtilis

[0111] Bacillus licheniformis

[0112] The premix was dropped into 5 liters of calcium chloride solution (6% w / v) and immobilized immediately, in the for...

Abstract

The present invention is directed to a composition for triggering microbiological processes in water, comprising: a) one or more chemoheterotropic microorganisms capable of decomposing water-immiscible substances; b) at least one source of oxygen and / or at least one oxidizing agent; c) at least one source of P and N; and d) at least one substance capable of immobilizing components a)-c).

Description

technical field [0001] The present invention relates to a composition for triggering microbial processes in water, in particular for the microbial decomposition of water-immiscible substances, such as crude oil and crude oil-derived substances. Background technique [0002] The invention discloses a composition for triggering microbial processes in water, a kit for forming a component comprising said components of said composition in different forms, a method of manufacture, such as a composition and its use Microbiologically decomposes water-immiscible substances, especially crude oil and crude oil-derived substances. [0003] Environmental pollution is the main cause affecting the global ecosystem. Oil spills, spills from oil tankers, release of wastewater and drilling activities are an offshoot of this environmental pollution that adversely affects aquatic ecosystems. Chemical means to control oil spills are rapidly developed, but they have the disadvantage of leaving c...
