“…This is consistent with the work of Barkai-Golan (2008) who reported that a certain amount of zinc in the culture medium stimulates the production of AFs in A. avus and A. parasiticus. Concurrently, strain IS26 contains genes involved in the production of Cys, His, Ser and Glu which are implicated in the zinc chelation and therefore inhibiting the activity of AFs biosynthesis-related enzymes (Ahmadian et al 2020).…”

“…The genome annotation of the strain IS26 revealed the presence of genes for polyamines that are involved in the resistance of maize plants to A. avus colonization and AFs contamination (Majumdar et al 2019). On the other hand, Ahmadian et al (2020) mentioned that natural compounds such as amino acids (Cys and His) behave as zinc chelators, inhibiting AFs production. This is consistent with the work of Barkai-Golan (2008) who reported that a certain amount of zinc in the culture medium stimulates the production of AFs in A. avus and A. parasiticus.…”

“…Some amino acids are known as natural zinc chelators, such as Cysteine (Cys), Histidine (His), Serine (Ser) and Glutamine (Glu). They have the intrinsic ability to chelate bivalent metals such as Zn 2+ (Ahmadian et al 2020).…”

This work aimed to study the interaction between Stenotrophomonas rhizophila strain IS26 and an isolate of Aspergillus flavus NRRL 62477 able to synthesize aflatoxin B1. Our results demonstrated that, when co-cultivated with A. flavus on ISP2 medium, the strain IS26 reduced the aflatoxin B1 residual concentration by 47%. The assembly of 5189077 Illumina's paired-end sequencing reads resulted in 42 contigs for a total genome assembly size of 4.09 Mb with 66.4% GC content. An overall total of 3624 genes was predicted using the NCBI Prokaryotic Genome Automatic Annotation Pipeline (NCBI-PGAAP). A total of 304 subsystems with 27% subsystem coverage was predicted using RAST annotation of the S. rhizophila strain IS26 genome. The genome sequence analysis of the strain IS26 detected the presence of genes involved in inhibition of aflatoxins (Afs) biosynthesis as well as genes involved in the degradation of AFs. Thus, these results suggest that S. rhizophila IS26 decreased aflatoxin B1 via down-regulated gene expression in terms of aflatoxin B1 biosynthesis and/or degradation of Afs. In summary, S. rhizophila IS26 can be employed for the biological reduction of aflatoxin B1 produced by A. flavus NRRL 62477.

Xyloketals, unique bioactive compounds, isolated from mangrove fungus Xylaria sp. (no. 2508), having multiple pharmacological, therapeutic properties, have prompted enormous research on their stereochemistry, bioactivity and synthetic attempts made toward this novel family. This review brings forward a systematic and comprehensive survey of the method of both racemic and enantioselective synthesis, reactivity, and biological properties associated with the xyloketal derivatives and their analogues.
