“…Besides, a few studies described the use of these bacteria for the production of biosurfactants in submerged fermentation. Chandankere et al (), Chandankere et al (), and Fooladi et al () mentioned that the biosurfactant produced may be useful in a variety of biotechnological and industrial processes, particularly in the oil and bioremediation industry of petroleum contaminants, and are still interesting for pharmaceuticals (Jemil et al, ; Joy et al, ; Zhang et al, ). In this way, the biosurfactants from Bacillus sp.…”

“…The O/W and W/O emulsifying activities obtained at the end of the 5‐day bioprocesses were 0.46 UE for EA O/W and 0.06 UE for EA W/O . These low values are justifiable because the biosurfactant produced by B. pumilus has a low molecular weight (Joy et al, ; Mulligan, ), and it has the most notable feature of reducing surface tension when dispersed in an aqueous medium.…”

The management of whey is a challenge for dairy products where the volume produced is remarkable. This problem is minimized through membrane separation processes (MSP) to obtain whey protein concentrate, which has high added value. However, a permeate effluent stream is still generated that is composed of lactose, vitamins, and minerals, which can serve as raw material for the production of biotechnological compounds. Thus, this study aimed to produce biosurfactants using the permeate from whey ultrafiltration as part of the culture media of the bioprocess, to recover the biosurfactant produced using MSP, and to identify the biocompound. The production was carried out using Bacillus methylotrophicus and Bacillus pumilus. The variables nitrogen source (urea or ammonium sulfate), nitrogen source concentration (0.5% or 1.0%), inducer (soybean oil or biodiesel), inducer concentration (1% or 2%), and the addition of micronutrients (with our without) were studied using a fractional factorial experimental design 2 5-1 IV . In the fermentation processes, it was possible to verify the biosurfactant production through the reduction of surface tension, obtaining a minimum value of 35.07 mN/m for B. methylotrophicus and 26.02 mN/m for B. pumilus. Recovery via MSP was an efficient strategy for biosurfactant purification, which was concentrated in the fraction of the retentate. We produced a high-value-added biocompound identified as surfactin, valuing the permeate residue from whey ultrafiltration.Results of mean AE standard deviation.

“…Aerobic and anaerobic BSF production are well documented in Pseudomonas, including in PH-degrading species [8]. Members of Ochrobactrum are known as hydrocarbonoclastic BSF-producers able to degrade hydrocarbons, mainly polycyclic aromatic hydrocarbons (PAHs) [55,56]. They are also known to reduce nitrate [57] or operate fermentative pathways [58] under anaerobic conditions.…”

Hydrocarbon bioremediation in anoxic sediment layers is still challenging not only because it involves metabolic pathways with lower energy yields but also because the production of biosurfactants that contribute to the dispersion of the pollutant is limited by oxygen availability. This work aims at screening populations of culturable hydrocarbonoclastic and biosurfactant (BSF) producing bacteria from deep sub-seafloor sediments (mud volcanos from Gulf of Cadiz) and estuarine sub-surface sediments (Ria de Aveiro) for strains with potential to operate in sub-oxic conditions. Isolates were retrieved from anaerobic selective cultures in which crude oil was provided as sole carbon source and different supplements were provided as electron acceptors. Twelve representative isolates were obtained from selective cultures with deep-sea and estuary sediments, six from each. These were identified by sequencing of 16S rRNA gene fragments belonging to Pseudomonas, Bacillus, Ochrobactrum, Brevundimonas, Psychrobacter, Staphylococcus, Marinobacter and Curtobacterium genera. BSF production by the isolates was tested by atomized oil assay, surface tension measurement and determination of the emulsification index. All isolates were able to produce BSFs under aerobic and anaerobic conditions, except for isolate DS27 which only produced BSF under aerobic conditions. These isolates presented potential to be applied in bioremediation or microbial enhanced oil recovery strategies under conditions of oxygen limitation. For the first time, members of Ochrobactrum, Brevundimonas, Psychrobacter, Staphylococcus, Marinobacter and Curtobacterium genera are described as anaerobic producers of BSFs. microorganisms have been identified as capable of producing BSF in anaerobiosis, with most of these belonging to the Bacillus and Pseudomonas genera [8].Hydrocarbonoclastic bacteria are characterized as being able to metabolize one or more PHs by using them as carbon and energy sources, usually preferring these substrates over others [9][10][11]. These bacteria are ubiquitous and can be found both in aerobic and anaerobic environments [12][13][14]. Natural anaerobic biodegradation of PHs occurs primarily in deep subsurface oil reservoirs [15], in the deep ocean near natural seeps [16,17] and in most microaerobic or anaerobic environments contaminated with PHs [18][19][20].While most of the deep-sea is characterized by low energy, productivity and biological activity rates [21], metabolic activity and biomass is higher in locations where seepage of PHs and other compounds occurs from within deep sediment layers to the seabed, such as hydrothermal vents and cold seeps [22,23]. Cold seeps, including mud volcanoes (MVs), are geologically diverse ecosystems associated with emissions of methane, other PHs and, often, reduced sulfate from the subsurface [24]. Deep-sea sediments, which are often anoxic below a thin upper layer [25], are known sinks for aliphatic and aromatic hydrocarbons [26,27]. Furthermore, bacterial communities from deep-sea surface sedi...

El petróleo es la principal materia prima usada como energético. En él se basa la economía de muchos países. Su utilidad estriba en su capacidad de transformación, como el caso de los combustibles. Sin embargo, el descenso en la producción mundial ha impulsado la búsqueda de métodos de recuperación mejorada de petróleo que además impacten lo menos posible los ecosistemas. Estos métodos son probados en condiciones controladas de laboratorio antes de ser aplicados en campo. En la literatura se reportan diversos métodos, que se describen en la presente investigación. Todos hacen uso de microorganismos y sus productos metabólicos. La eficiencia entre un método y otro depende de la geología del yacimiento y de las características biológicas de los microorganismos empleados en la recuperación del petróleo.
