Before agar, microbiologists had experimented with other foodstuffs as microbial media. They turned to substances rich in the starches, proteins, sugars, fats, and minerals that organisms need for growth, testing with broths, bread, potatoes, polenta, egg whites, coagulated blood serums, and gelatine. However, none worked particularly well: all were easily broken down by heat and microbial enzymes, and their surface, once colonized, became mushy and unsuitable for isolating microbes.
Recently, Yuanji Foods submitted its listing application to the Hong Kong Stock Exchange. Its operating figures show a mix of scale expansion and mounting profitability pressure. In 2023 and 2024, the company recorded revenue of RMB 2.026 billion and RMB 2.561 billion, respectively, up 26.4% year over year. Revenue for the first three quarters of 2025 reached RMB 1.982 billion, up 11% year over year. While revenue continued to grow, the growth rate clearly slowed. Profitability fluctuated significantly: net profit fell 15% year over year in 2024 to RMB 142 million, then rebounded to RMB 142 million in the first three quarters of 2025 (matching the full-year 2024 level in just nine months). Adjusted net profit was RMB 192 million, up 31% year over year, with the increase largely driven by a reduction in share-based payment expenses.。WPS官方版本下载对此有专业解读
