“…Secondly, K-2 T and S1 were able to grow at pH 1.5-12 with an optimal growth pH of 7.0. Contrastingly, the pH range of other species under the genus Talaromyces was only 4-8 (Table 2), except for T. aculeatus which could survived at pH of 1-7 (Katar et al, 2017;Suleman et al, 2022). Thirdly, the results revealed that K-2 T and S1 were halotolerant and ourished at a NaCl range of 0-14% (w/v) which also was clearly different from other species of genus Talaromyces.…”

“…Physicochemical characteristics of the isolates K-2 T and S1 were tested and compared with other species under the genus Talaromyces as shown in Table 2. Firstly, K-2 T and S1 could grow over a wide temperature range (4-50°C) with an optimal growth temperature of 28°C, which signi cantly differed from other species like T. assiutensis (Yaguchi et al, 1994), T. aculeatus (Katar et al, 2017;Suleman et al, 2022), T. trachyspermus (Fang and Shi, 2016), T. alveolaris (Guevara et al, 2017). Secondly, K-2 T and S1 were able to grow at pH 1.5-12 with an optimal growth pH of 7.0.…”

Two fungal strains (K-2 T and S1) were isolated from the deepest ocean sediment of the Challenger Deep located in the Mariana Trench. The internal transcribed spacer (ITS) gene sequences of the isolates K-2 T and S1 differed from their closely related species, such as Talaromyces assiutensis, and T. trachyspermus, by exhibiting 7%-7.88% sequence divergence (30-36 nt substitutions and 4-9 gaps). Phylogenetic analyses based on single and concatenated alignments of the ITS gene, the β-tubulin (benA) gene, the calmodulin (cam) gene, and the second-largest subunit fragment of RNA polymerase II (rpb2) gene showed that the isolates K-2 T and S1 were clustered together with other species of the genus Talaromyces such as T. trachyspermus and T. assiutensis, as evidenced by the position on a terminal branch with high bootstrap support. They could also be distinguished from their closest relatives with validly published names by morphological and physiological characteristics, for example, growing at 4-50°C with pH 1.5-12. Based on phylogenetic, morphological, and physicochemical properties, they represent a novel species in the genus Talaromyces, for which the name Talaromyces sedimenticola sp.nov. is proposed. The type strain is K-2 T (= GDMCC 3.746 = JCM 39451).

Photodegradation of the ink‐jet prints is a complex process in which many external and internal factors are involved. Nevertheless, the role of colorants and various accompanying substances in the ink is often overlooked. Our research work aimed to determine the fastness of water‐based ink‐jet inks in aqueous solutions. A printing ink often contains a complex mixture of colorants to achieve optimal optical properties of color and a suitable fastness of the print. Therefore, we investigated the composition and stability of cyan, magenta, yellow, and black inks under the influence of UVC light in the presence of oxygen as well as in an inert environment based on TLC chromatography and spectrophotometric analysis. The process of photodegradation was evaluated based on ink amount and half‐life. According to the results, the majority of inks consist of at least two colorants that differ in color and polarity. The results have shown that the presence of oxygen negatively affects the stability of inks; therefore, the inert atmosphere prolongs the durability of ink in water solution.

“…Due to its resistance to extreme conditions, several Talaromyces species have been exploited in industrial and environmental biotechnology research. They also offer prospective biomasses for use in absorptive technology (Okparanma & Ayotamuno, 2008;Katar et al, 2017). T. helicus has been frequently utilized to eliminate cobalt, copper and cadmium from polluted sediments of industries (Guerra Sierra et al, 2022).…”

Lead (Pb) is one of the most serious environmental pollutants due to its accumulation in soil and water, which causes serious problems for human health and the environment. Biosorption using dead microbial biomass represents one of the most innovative, economically feasible, and environmentally safe tools for removing heavy metals. Therefore, the present study focused on removing lead using Talaromyces stipitatus as a dead fungal biomass and evaluating its impact on animal toxicity. Lead-tolerant fungi were isolated from polluted sites, and T. stipitatus was chosen for the biosorption investigation based on its distinctive characteristics and identified according to its morphological and molecular characteristics then submitted to the GenBank database under accession number OQ691598. The biosorption capacity and efficiency of Pb were evaluated at 28±2°C with various parameters, which included pH, contact time and biomass concentration. Our findings showed that the highest significant biosorption capacity (56.10 mg/g) and efficiency (96.62%) for lead removal from aqueous solutions (lead initial concentration, 58 mg/L) were achieved at pH 6 and 30 minutes of contact time, with a biomass content of 1 g/L. Three groups of male albino rats were used after the biosorption study; the negative control group orally received double-distilled water only; the positive control group orally received Pb aqueous solution (58 mg/L) for 30 days, and the treatment group orally received Pb aqueous solution (58 mg/L) after being treated with T. stipitatus as biosorbent material for 30 days. The findings revealed that Pb induced a significant decrease in weight gain and relative weights of liver and testis, sperm count and motility, as well as serum total protein and albumin levels, but it induced a significant increase in relative weights of lung, brain, and prostate, serum aspartate aminotransferase and alanine aminotransferase activities, serum urea, creatinine, and uric acid levels, sperm abnormalities, and bioaccumulation of Pb traces in liver and kidney tissues with several histopathological changes in the liver, kidney, testis and epididymis of male albino rats. The treatment group showed considerable improvements in each of the aforementioned results in animals. These findings suggest that T. stipitatus is capable of removing lead from polluted waters without posing any health risks to animals. To the best of our knowledge, no previous report has documented the use of T. stipitatus for lead removal and its effect on animal toxicity.
