It’s also worth noting that even if alternatives superior to agar were found, scientists are reluctant to abandon established protocols (even when microbiologists do use other jellies, they often still add agar to the mix, for example, to increase the gel strength of the solid media). As agar has been the standard gelling agent in microbiology for around 150 years, an enormous infrastructure of standardized methods, reference values, and quality control procedures has emerged around its specific properties. Switching to a different medium (even a superior one) means results may not be directly comparable to decades of published literature or to other laboratories’ findings.
Moving beyond just black and white towards full-colour variable palettes presents another set of problems. Taking the methods presented above and quantising an image using an arbitrary colour palette reveals that error-diffusion is also better at preserving colour information when compared to ordered dithering.。业内人士推荐WPS下载最新地址作为进阶阅读
