Exploring Pongamia seed cake hydrolysate as a medium for microbial lipid production by Aspergillus ochraceus

Publication date: Available online 15 February 2020Source: Biocatalysis and Agricultural BiotechnologyAuthor(s): Harshitha Madhusoodan Jathanna, Chandrayan Vaman Rao, Louella Concepta GoveasAbstractBiofuels and their production is the need of the hour considering the current fuel crisis. In this regard, ways of mitigating biodiesel production costs is being actively researched upon. With the same intention, in the present work, an investigation was carried out to test the capability of utilizing the hydrolysates of de-oiled Pongamia seed cake, a byproduct of biodiesel, for microbial lipid production using Aspergillus ochraceus. This is the first time A. ochraceus is being reported to be used to evaluate its oleaginous property. Also, Pongamia seed cake is the novel source being used for microbial lipid production. The different variants of the seed cake based medium proved acid hydrolysate of de-oiled seed cake to be the effective medium for lipid production. The values recorded for maximum biomass titer, lipid titer and lipid content were 3.065 ± 0.248 g/L, 0.849 ± 0.056 g/L and 28.93%, respectively, upon using acid hydrolysate of the seed cake. The fatty acid composition obtained by GC-MS analysis revealed the presence of linoleic, oleic, stearic and palmitic acids as the major fatty acid components in the lipids produced proving their similarity to the vegetable oils. The fuel properties of the lipids produced were found be in accordance with the ...

Voriconazole is the drug of choice for prophylaxis and treatment of Aspergillus infection in LTx recipients. Voriconazole has a narrow therapeutic index; thus, therapeutic drug monitoring (TDM) is required to prevent treatment failure and reduce the risk of adverse drug events (ADE). We aim to determine the frequency and type of ADE associated with voriconazole and describe voriconazole dosing and TDM in LTx recipients.

Aspergillus fumigatus is responsible for Invasive aspergillosis (IA). The role of other closely related species such as Aspergillus lentulus and Aspergillus viridinutans which are members of the section Fumigati (A. fumigatus complex) in the setting of pre-emptive therapy in lung transplant recipients is not well defined, and may be associated with poor clinical response.

AbstractFlow cytometric quantification of CD154+ mould specific T-cells in antigen-stimulated peripheral blood mononuclear cells (PBMCs) or whole blood has been described as a supportive biomarker to diagnose invasive mould infections and to monitor therapeutic outcomes. As patients at risk frequently receive immunosuppressive and antifungal medication, this study compared the matrix-dependent impact of representative drugs on CD154+ T-cell detection rates. PBMCs and whole blood samples from healthy adults were pre-treated with therapeutic concentrations of liposomal amphotericin B, voriconazole, posaconazole, cyclosporine...

In the fungal pathogen Aspergillus fumigatus, resistance to azole antifungals is often linked to mutations in CYP51A, a gene that encodes the azole antifungal drug target lanosterol 14α-demethylase. The aim of this study was to investigate whether similar changes could be associated with azole resistance in a Malaysian Fusarium solani species complex (FSSC) isolate collection. Most (11 of 15) clinical FSSC isolates were Neocosmospora keratoplastica and the majority (6 of 10) of environmental isolates were Neocosmospora suttoniana strains. All 25 FSSC isolates had high minimum inhibitory concentrations (MICs) for itra...

Aflatoxins are the highly toxic secondary metabolites of certain fungi, being mainly produced by Aspergillus flavus and Aspergillus parasiticus. Aflatoxins are classified as group 1 category carcinogens by the International Agency for Research on Cancer (IARC). A large number of food commodities are reported to be contaminated with aflatoxins. Tea is the world’s second most consumed beverage and the consumption of tea is increasing day by day. Besides being a source of several health promoting substances, tea leaves are also reported to be contaminated with aflatoxins. However, not a single study is reported from Pak...

Abstract Aspergilloma, also known as mycetoma or fungus ball, is the most common manifestation of pulmonary involvement by Aspergillus species. The fungal ball typically forms within preexisting cavities of the lungs. Diagnosis requires both radiographic evidence along with serologic or microbiologic evidence of Aspergillus species involvement. While clinical features such as hemoptysis, chest pain, shortness of breath, cough, and fever are helpful in diagnosis, they are non-specific symptoms. Surgery is currently the mainstay of treatment for aspergilloma but is associated with considerable mortality and morbidit...
