Abstract
OBJECTIVES This study aimed to isolate red yeast from sap, bark and slime exudates collected from Polish birch forests and then assessment of their biotechnological potential. RESULTS 24 strains of red yeast were isolated from the bark, sap and spring slime fluxes of birch (Betula pendula). Strains belonging to Rhodotorula mucilaginosa (6), Rhodosporidiobolus colostri (4), Cystrofilobasidium capitaum (3), Phaffia rhodozyma (3) and Cystobasidium psychroaquaticum (3) were dominant. The highest efficiency of carotenoid biosynthesis (5.04 mg L-1) was obtained by R. mucilaginosa CMIFS 004, while lipids were most efficiently produced by two strains of P. rhodozyma (5.40 and 5.33 g L-1). The highest amount of exopolysaccharides (3.75 g L-1) was produced by the R. glutinis CMIFS 103. Eleven strains showed lipolytic activity, nine amylolytic activity, and only two proteolytic activity. The presence of biosurfactants was not found. The growth of most species of pathogenic moulds was best inhibited by Rhodotorula yeasts. CONCLUSION Silver birch is a good natural source for the isolation of new strains of red yeast with wide biotechnological potential.

Arch Microbiol 2024; 206:245.

Abstract
Production of carotenoids by yeast fermentation is an advantaged technology due to its easy scaling and safety. Nevertheless, carotenoid production needs an economic culture medium and other efficient yeast stains. The study aims to isolate and identify a yeast strain capable of producing carotenoids using a cost-effective substrate. A new strain was identified as Rhodotorula toruloides L/24-26-1, which can produce carotenoids at different pretreated and unpretreated sugarcane molasses concentrations (40 and 80 g/L). The highest biomass concentration (18.6 ± 0.6 g/L) was reached in the culture using 80 g/L of hydrolyzed molasses. On the other hand, the carotenoid accumulation reached the maximum value using pretreated molasses at 40 g/L (715.4 ± 15.1 µg/g d.w). In this case, the β-carotene was 1.5 times higher than that on the control medium. The yeast growth in molasses was not correlated with carotenoid production. The most outstanding production of The DPPH, ABTS, and FRAP tests demonstrated the antioxidant activity of the obtained carotenogenic extracts. This research demonstrated the R. toruloides L/24-26-1 strain biotechnological potential for carotenoid compounds. The yeast produces carotenoids with antioxidant activity in an inexpensive medium, such as sulfuric acid pretreated and unpretreated molasses.

Sustainable approach to recover β-carotene and astaxanthin from Phaffia rhodozyma grown in a stirred-tank bioreactor under the influence of magnetic fields. BIORESOURCE TECHNOLOGY 2023; 390:129906. [PMID: 37866770 DOI: 10.1016/j.biortech.2023.129906] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Revised: 10/03/2023] [Accepted: 10/19/2023] [Indexed: 10/24/2023]
Abstract
This study aimed to produce carotenoids by Phaffia rhodozyma in a stirred-tank bioreactor under the influence of magnetic fields (MF) and to evaluate a sustainable approach to recover them from the yeast biomass. MF application proved to be effective in increasing 8.6 and 22.9 % of β-carotene and astaxanthin production, respectively. Regarding solid-liquid extraction (SLE), the ability of aqueous and ethanolic solutions of protic ionic liquids (PILs) was determined. β-carotene and astaxanthin recovery yields increased with the anion alkyl chain length hydrophobicity. [Pro][Oct]:EtOH (50 % v v-1) was selected as the effective solvent. Moreover, it led to improvement in carotenoid stability at different storage temperatures over time in comparison with the control. This study is one of the first to describe an effective and sustainable approach to move carotenoid production from shake flasks to a bioreactor under the influence of MF and recover carotenoids from P. rhodozyma biomass.

Update on the application of magnetic fields to microalgal cultures. World J Microbiol Biotechnol 2022; 38:211. [PMID: 36053367 DOI: 10.1007/s11274-022-03398-y] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2022] [Accepted: 08/21/2022] [Indexed: 12/14/2022]
Abstract
Several studies have shown that any magnetic field (MF) applied to microalgae modifies its cultivation conditions and may favor biomolecule production since it interacts with the microorganisms and affect their growth. As a result, there are changes in concentrations and compositions of biomass and biomolecules. This review aims at updating MF applications to microalga cultures that were reported by studies conducted in the last 5 years. It shows the main studies that reached positive results of carbohydrate, lipid, protein and pigment production. Effects of MFs may be positive, negative or null, depending on some factors, such as intensity, exposure time, physiological state of cells and application devices. Therefore, this review details cultivation conditions used for reaching high concentration of biomolecules, explains the action of MFs on microalgae and describes their applicability to the biorefinery concept.
