“…No reports were found in the literature regarding Pz, however it is known that Aspergillus sp. are well known for secreting large amounts of enzymes (Hernández-Martínez et al 2011) and for this reason they are often mentioned in several studies as efficient producers of lignolytic complex enzymes, among them the work of Reis et al (2019) where A. niger is cited as a viable alternative production of multiple enzymes, including MnP and Lac. In addition, the A. niger strain can be adopted as a biodegradable agent for complex compounds, such as effluent discoloration composed of reactive yellow and reactive red dye, reaching 98.62% and 92.42% removal, respectively, as described by Salem et al (2019), and as an alternative, A. niger it can also biodegrade the Congo Red dye, reaching a discoloration rate of 97% as a result ligninolytic enzymes action, where MnP plays a crucial role in discoloration (Asses et al 2018).…”

Fungi are excellent producers of extracellular enzymes. Therefore, the present study aimed to investigate the screening of marine fungi, which are laccase and manganese peroxidase potential producers, in solid fermentation for future applications in bioremediation processes of contaminated sites. For this purpose, twolevel factorial planning was adopted, using time (6 and 15 days) and the absence or presence of oil (0 and 1%) as factors. The semi-quantitative evaluation was carried out by calculating radial growth, enzyme activity and enzyme index by measuring phenol red or syringaldazine oxidation halo. The results showed that all the studied strains showed a positive result for manganese peroxidase production, with an enzymatic activity in solid medium less than 0.61, indicating a strongly positive activity. Through the enzyme index, the study also showed prominence for Penicillium sp. st rains, with values > 2. The enzyme index increase in oil presence and the inexpressive use of the genera studied for ligninolytic enzymes production from crude oil demonstrated these data importance for fermentative processes optimization. Considering the ability of these strains to develop into recalcitrant compounds and the potential for manganese peroxidase production, they are indicated for exploitation in various bioremediation technologies, as well as other biotechnological applications.

Essential Oils - Advances in Extractions and Biological Applications

View full text Add to dashboard Cite

Essential oils are formed by a complex matrix of substances that are biosynthesized in the secondary metabolism of plants. Nowadays, different ecofriendly extraction techniques (e.g., ultrasound-, microwave-, enzyme-assisted extraction, and supercritical fluid by CO2, etc.) have been adopted to obtain essential oils. These techniques provide unique quality of essentials oils or extracts from aromatic plants in a short time with high energy savings. Essential oils not only impart aroma, but also possess antimicrobial and antioxidant activities. Health limitations in the use of synthetic additives have drawn researchers’ attention towards essential oils as safe natural preservatives. Therefore, this chapter summarizes novel technologies to recover essential oils or extracts. In addition, it focuses on application of essential oils and their constituents as green preservatives to retard microbial growth and oxidative spoilage.

“…Higher enzyme concentration causes higher degree of cell wall disruption. However, with continuous increase in concentration, a point is reached from where on, further increasing the concentration has almost negligible effect on the yield [34,36,39] and [40]. Some of the research examples where enzymatic pre-treatment is used for EOs extraction can be seen in Table 2.…”

The increasing demand of essential oils (EOs) as nutraceuticals, food, pharmaceutical, and cosmetic ingredients in the current scenario has opened up new avenues for their large-scale production. India's biodiversity and scientific development promise to make it leading country in aroma business in the coming years. Plant resources contain the natural and aromatic EOs in small quantities which are difficult to extract. These EOs can be produced by different techniques including conventional, nonconventional, and biochemical processing strategies. The combination of conventional and non-conventional techniques has proved to be potential extraction methods. They ensure EO production with shorter extraction time, higher efficiency, and enhanced product quality. There has been a constant urge to develop greener synthesis and extraction procedures for EOs due to the adverse effects caused to the environment by the physical and chemical methods. Researchers are exploring bioengineering techniques to enhance the quality and quantity of EOs using various microorganisms and enzymes. Metabolic engineering and biotransformation can tackle the uncertainty of raw material supply for EOs like the climatic changes, natural disasters, and plant diseases. With high efficiency, specificity, and purity of products, these methods are highly beneficial for future applications. This review presents a detailed description of the current status of EO production, their potential extraction techniques, and life cycle assessment (LCA) of essential oil production. The recent developments in the direction of bioengineering for scalable synthesis of EOs are also highlighted in this review.
