Abstract
d-Arabitol, an alternative sweetener to sugar, has low calorie content, high sweetness, low glycemic index, and insulin resistance-improving ability. In this study, d-arabitol-producing yeast strains were isolated from various commercial types of miso, and strain Gz-5 was selected among these strains. Phylogenetic tree analysis of the internal transcribed spacer sequence revealed that strain Gz-5 was distinct from Zygosaccharomyces rouxii, a major fermenting yeast of miso. The strain, identified as Zygosaccharomyces sp. Gz-5, grew better than other Z. rouxii in 150 g/L NaCl and produced 114 g/L d-arabitol from 295 g/L glucose in a batch culture for 8 days (0.386 g/g-consumed glucose). In a fed-batch culture, the yeast produced 133 g/L d-arabitol for 14 days, and the total d-arabitol amount increased by 1.75-fold. These results indicated that Zygosaccharomyces sp. Gz-5, a non-genetically modified strain, has excellent potential for the industrial production of d-arabitol.

Abstract
Pigments and other secondary metabolites originating from marine microbes have been a promising natural colorants and drugs for multifaceted applications. However, marine actinobacteria producing such natural molecules are least investigated in terms of their taxonomy, chemical diversity and applications in biomedical, textile, and food industries. In this study, sioxanthin pigment-producing Gram-positive actinobacteria, Micromonospora sp. strain SH-82 was isolated from a marine sponge, Scopalina hapalia, and its whole genome was analyzed. Strain SH-82is a prolific producer of diverse chemical molecules as it produced more compounds on A1 medium with different culture conditions. The genome size of SH-82 is 6.24 Mb (6,246,890 bp) carrying 23 identified biosynthetic gene clusters. A total of 5415 CDS, 60 tRNA, 9 rRNA, and 1 tmRNA are identified from SH-82 genome. The GC content (%) of whole genome was 71.6%. Strain SH-82 harbors genes encoding type I, type II, and type III polyketide synthases. Based on the multi-locus sequence analysis and fatty acid methyl ester (FAME) composition, strain SH-82 is confirmed as a novel species. The genetic information of Micromonospora sp. SH-82 has been deposited to NCBI under the BioProject ID PRJNA1087320, with corresponding identifiers in the Sequence Read Archive (SRA) as SAMN40439676 and the Genome accession as CP148049.

Quantification and modeling of macroparticle-induced mechanical stress for varying shake flask cultivation conditions. Front Bioeng Biotechnol 2023; 11:1254136. [PMID: 37731767 PMCID: PMC10507416 DOI: 10.3389/fbioe.2023.1254136] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Accepted: 08/08/2023] [Indexed: 09/22/2023] Open
Abstract
In biotechnological processes, filamentous microorganisms are known for their broad product spectrum and complex cellular morphology. Product formation and cellular morphology are often closely linked, requiring a well-defined level of mechanical stress to achieve high product concentrations. Macroparticles were added to shake flask cultures of the filamentous actinomycete Lentzea aerocolonigenes to find these optimal cultivation conditions. However, there is currently no model concept for the dependence of the strength and frequency of the bead-induced stress on the process parameters. Therefore, shake flask simulations were performed for combinations of bead size, bead concentration, bead density and shaking frequency. Contact analysis showed that the highest shear stresses were caused by bead-bottom contacts. Based on this, a newly generated characteristic parameter, the stress area ratio (SAR), was defined, which relates the bead wall shear and normal stresses to the total shear area. Comparison of the SAR with previous cultivation results revealed an optimum pattern for product concentration and mean product-to-biomass related yield coefficient. Thus, this model is a suitable tool for future optimization, comparison and scaling up of shear-sensitive microorganism cultivation. Finally, the simulation results were validated using high-speed recordings of the bead motion on the bottom of the shake flask.

Influence of Cultivation Conditions on the Sioxanthin Content and Antioxidative Protection Effect of a Crude Extract from the Vegetative Mycelium of Salinispora tropica. Mar Drugs 2021; 19:md19090509. [PMID: 34564171 PMCID: PMC8469146 DOI: 10.3390/md19090509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2021] [Revised: 09/01/2021] [Accepted: 09/06/2021] [Indexed: 11/24/2022] Open
Abstract
Due to their bioavailability, glycosylated carotenoids may have interesting biological effects. Sioxanthin, as a representative of this type of carotenoid, has been identified in marine actinomycetes of the genus Salinispora. This study evaluates, for the first time, the effect of cultivation temperature (T) and light intensity (LI) on the total cellular carotenoid content (TC), antioxidant activity (AA) and sioxanthin content (SX) of a crude extract (CE) from Salinispora tropica biomass in its vegetative state. Treatment-related differences in TC and SX values were statistically significantly and positively affected by T and LI, while AA was most significantly affected by T. In the S. tropica CE, TC correlated well (R2 = 0.823) with SX and somewhat less with AA (R2 = 0.777). A correlation between AA and SX was found to be less significant (R2 = 0.731). The most significant protective effect against oxidative stress was identified in the CE extracted from S. tropica biomass grown at the highest T and LI (CE-C), as was demonstrated using LNCaP and KYSE-30 human cell lines. The CE showed no cytotoxicity against LNCaP and KYSE-30 cell lines.
