“…The fixed smears were washed with water after flooding with crystal violet. Then were flooded with mordant Gram's iodine, decolorized with ethanol, washed with water, and counterstained with safranin for 45 s. Then the glass slides were washed with water, dried with tissue paper and examined under oil immersion (100 ×) [4] .…”

Lactic acid bacteria (LAB) are the dominant and advantageous microorganisms of raw and fermented camel milk; these bacteria have the potential to develop functional camel-milk-derived products and can be used in dairy technology. This article presents data on the diversity of LAB, isolated from raw and fermented camel milk. In total, from two samples of raw camel milk and one sample of fermented camel milk, seventeen isolates of LAB were isolated. The data of genetic identification of strains, which was performed through analysis of the 16S rRNA gene sequence, is presented. According to this data, the prevailing number of LAB belong to the Lactobacillus genus – 53%. Following species of Lactobacillus bacteria were determined – fermentum, casei, curizae, oryzae, brevis, plantarum, rhamnosus, paracasei. The next prevailing number of lactic acid bacteria belong to the Pediococcus genus – 23%, represented by acidilactici and pentosaceus species. Lactic acid bacteria of Weissella and Enterococcus genera comprised 12% each from total abundance. These results can be used for a further selection of potential starter cultures for functional camel-milk-derived products.

“…Одним из методов биоконверсии органических отходов в экологически чистое удобрение является компостирование. В ускорении процесса компостирования органических отходов существенную роль играют микроорганизмы, продуцирующие гидролитические ферменты (амилаза, протеаза, целлюлаза, липаза, уреаза), ответственные за разложение органических соединений [8]. В статье представлены данные по характеристике ферментативного потенциала бактерий, выделенных из осадка сточных вод канализационно-очистных сооружений г. Нур-Султан, Рудный, Форт-Шевченко, дачной почвы и свежескошенной травы с дачного участка (г. Нур-Султан), для переработки органических отходов и выявления активных штаммов.…”

Из иловых осадков сточных вод канализационно-очистных сооружений (г. Нур-Султан, Рудный, Форт-Шевченко), почвы и свежескошенной травы, отобранной на дачном участке (г. Нур-Султан), выделено 60 культур микроорганизмов. Для отбора активных штаммов, способных перерабатывать осадки сточных вод, все микроорганизмы, выделенные в чистую культуру, были протестированы на ферментативную активность -липолитическую, протеолитическую, целлюлолитическую, амилолитическую. По результатам исследований отобрано 15 изолятов с разными фенотипическими признаками, обладающих наиболее высокой ферментативной активностью. Изучены культурально-морфологические свойства отобранных изолятов, способность к спорообразованию и к росту при различных температурах. Из отобранных культур 3 изолята способны к росту при температуре выше 45 °С. Для остальных культур оптимальным для роста является диапазон температур 28-37 °С. Идентификация отобранных микроорганизмов выявила принадлежность выбранных штаммов к роду Rhodococcus rhodochrous, Cryseobacterium arachidis, Pseudoxanthomonas sp., Bacillus megaterium, Pediococcus acidilactici, Paenibacillus residui, Brevibacillus invocatus, Bacillus lichenoformis, 2 штамма отнесены к Bacillus cereus, 3 к Enterobacter cloacae и 2 к Ochrobactrum intermedium. Отобранные штаммы микроорганизмов с наибольшей ферментативной активностью могут стать претендентами на создание на их основе эффективного биопрепарата для переработки иловых осадков сточных вод канализационно-очистных сооружений городов.

“…Guo et al (2021) reported that conventional treatment and recycling methods of organic solid waste contain inherent flaws, such as low efficiency, low accuracy, high cost, and potential environmental risks, and most studies have been focused on municipal solid waste management, followed by anaerobic digestion, thermal treatment, composting and landfill. Moldagulova et al (2020) reported that thermotolerant microorganisms play an important role in the composting process of organic waste which are responsible for the degradation process of organic compounds owing to their enzymatic activity in the high-temperature phase of composting. Duan et al (2020) found that biorefinery facing a big challenge in technical, financial and social awareness, and circular bioeconomy requires coordinated policy intervention in socioeconomic.…”

Food loss may occur in production, storage, transport, and processing, which are the stages of the value chain with the lowest returns. The current searching was done by the keywords in main indexing systems including PubMed/MEDLINE, Scopus, and Institute for Scientific Information Web of Science as well as the search engine of Google Scholar. The most important points challenging areas that represent opportunities for stakeholders to look into in China are, put in place suitable economic incentives to encourage restaurants to get more involved in the formal system, create a comprehensive regulation system to benefit all relevant stakeholders by clearly defining their respective roles and responsibilities, which is necessary for the proper functioning of the whole system. In China, the most important regulations, policies and plans are regulations on safety issues of food waste treatment, detailed countermeasures on organizing, educating, supervising, and inspecting the work on food waste reduction in China, and detailed plant for household waste collection and treatment, issued by Chinese government, state council, and ministry of environmental protection. Setting national goals, awareness-raising campaigns, strict and appropriate regulation, stakeholder engagement, biorefinery and food waste recycling to animal feed are important strategies for better waste management. The most important food waste management practices in China are source separation, animal feed, rendering, composting, co-digestion, anaerobic digestion, incineration, landfill, and etc. Understanding social factors influencing household behavior is utmost importance; public education and specific communication highly contribute to improve recycling.
