Summary: This study explored the differences in bacterial diversity during the four developmental stages of the black soldier fly (BSF) using a metabarcoding approach. The results showed significant changes in bacterial community composition and species richness along the BSF life cycle, and identified nine prevalent core microbiota. The study also inferred 27 potential metabolic pathways differentially used among the BSF life cycle. This research provides a better understanding of metabolic processes during BSF development and their implications for bio-waste processing.

Summary: With the shortage of protein feed resources due to increasing global population, finding alternative protein sources has become urgent. Black soldier fly larvae are rich in fatty acids, proteins, and minerals, with no negative effects on animal growth and meat quality. However, legal and consumer acceptance constraints exist when using black soldier fly larvae as feed.

Summary: The scarcity of high-quality, expensive animal feed is driving up animal husbandry costs. Researchers are investigating alternative feed resources derived from black soldier fly larva, including the use of oil from black fly larvae as a byproduct. A study using in vitro gas production techniques found that adding 4% black soldier fly larva oils at different roughage-to-concentrate ratios increased propionate levels, decreased methane emission, and preserved dry matter degradability.

Summary: The trials showed that diets containing partially defatted black soldier fly larvae meal and oil were well accepted and tolerated by dogs, with no negative impacts on their health or physiology. The inclusion of black soldier fly meal and oil in dog diets did not affect general health and could be considered safe for consumption.

Summary: The aim of this study was to investigate the effect of incorporating black soldier fly larvae as an alternative protein source on the digestibility of amino acids in weaned pigs. The results showed that the digestibility of amino acids in black soldier fly larvae was lower compared to fish meal, but processing and thermal conditioning techniques can improve its digestibility.

Summary: The black soldier fly larvae have been recognized for their efficient bioconversion of organic waste. Intestinal microorganisms play a crucial role in various insect functions, and the addition of specific bacteria can affect the intestinal microbiota of the larvae. By introducing six different potential functional strains, it was observed that the abundance of Lysinibacillus significantly increased, potentially contributing to the larvae's characteristics.

Summary: The rapid increase in population in Pakistan has led to a significant rise in municipal solid waste, causing serious public health and environmental issues. Current waste management techniques in Pakistan are inadequate and not cost-effective. The black soldier fly larvae technology offers a viable and environmentally friendly solution for managing organic waste effectively.

Summary: The study found that ex situ fermentation greatly enhances the degradation of coconut endosperm waste (CEW) compared to in situ fermentation, even with a low proportion of fungal inoculation. This method can also promote the growth of black soldier fly larvae, leading to more efficient waste management. Additionally, the presence of Rhizopus oligosporus at 0.5-1.0 wt % was considered optimal for fermenting CEW via ex situ mode before valorization by BSFL.

Summary: This study analyzed the dynamics of the intestinal bacterial community of black soldier fly larvae and found significant differences in bacterial composition among different larval instars. Certain bacteria, such as Citrobacter, Dysgonomonas, Klebsiella, Ochrobactrum, and Providencia, were found to promote the growth and development of black soldier flies.

Summary: By studying the yeast microbiome in Drosophila melanogaster in different salt concentrations, it was found that as the salt concentration increases, the abundance and composition of yeasts undergo significant changes. The relationship between yeast species and abundance and the adaptation of Drosophila to high-salt environments may vary at different stages of adaptation.

Summary: Microbiological investigation of the cloth exposed on the International Space Station (ISS) for 8 years revealed viable Rhodotorula mucilaginosa yeasts. These yeasts showed similarities to strains isolated from the ISS interior, and physiological testing indicated some differences between the cloth strain and the cultured yeast strain previously detected in the ISS interior. The investigation also demonstrated the changing sensitivity of fungal strains to antifungal drugs depending on the number of passages.

Summary: The type strain Rhodotorula pinalis VKM Y-2963 was genetically and phylogenetically characterized, and it was found to be conspecific with strains from Sphagnum mosses and dead conifer needles. Phylogenetic analysis suggests that the species Rh. pinalis should be reassigned to the genus Fellozyma.

Summary: A study conducted in southern cities of Russia and the Republic of Crimea in 2020 examined the presence of yeasts in soil samples from streets, urban parks, and suburban areas. The study compared the results with a previous study conducted in 2019 and found that the yeast abundance was slightly higher in 2020 after the reduction in household waste deposition. The composition of yeast communities also changed, with an increase in autochthonous basidiomycetous yeast species and a decrease in clinically significant yeasts.

Summary: Laser-assisted bioprinting of microbial cells using hydrogel microdroplets is a rapidly developing field. This study successfully demonstrated the bioprinting of yeast cells using hydrogel, and evaluated their viability. The results showed that the average viability rate after laser-induced transfer in hydrogel microdroplets was 77%, with some strains showing a viability rate exceeding 90%. Differences were found in the laser transfer of yeast cells from different phyla, with basidiomycetes forming a greater number of colonies than ascomycetes.

Summary: Leucosporidium egoroviorum f.a., sp. nov., a new anamorphic species of the basidiomycetous yeasts, was isolated as an endophyte from the fruits of Cucurbita pepo subsp. pepo (zucchini). The new species showed significant differences in genetic, physiological, and morphological characteristics compared to closely related species L. fellii, L. intermedium, and L. krtinense. The holotype KBP Y-6804T is preserved in a metabolically inactive state, and the isotype strains are VKM Y-3065, DSM 113574, and CBS 17590. The MycoBank number is MB 842805.

Summary: The study investigated yeast complexes in urban areas by studying mines on tree leaves and undamaged leaves. It was found that the abundance of yeasts increased significantly during the development of mines, and no significant differences were observed between mines formed by different insects on different trees. Twelve yeast species were observed, with ascomycetous yeasts Hanseniaspora uvarum and H. occidentalis dominating the mines.

Summary: This study evaluated the phytohormonal activity of Metschnikowia pulcherrima yeast strains isolated from the internal tissues of fruits. The production of IAA, zeatin, and GA3 was determined using chromatographic methods. The results showed that the strains had the highest activity in IAA synthesis, while the levels of zeatin and GA3 were much lower. These findings suggest that M. pulcherrima yeast strains may have a role in promoting plant development and growth.
