Final answer:

The medium experiencing fungal-like contamination is Murashige and Skoog medium with 3-6 millimeters of sucrose concentration. The contamination appears as squiggly and string-like structures when observed under a compound microscope at a magnification of 200x, 400x, 600x. Introducing antifungal agents to the medium may help address the contamination issue.

Step-by-step explanation:

The medium that is experiencing fungal-like contamination when growing S. lycopersicum is Murashige and Skoog medium. The sucrose concentration in the medium is typically 3-6 millimeters. The agar type included in the contaminated medium is Luria-Bertani agar. S. lycopersicum is grown in a day-night cycle temperature of 25°C - 24°C. The contamination structures observed under the microscope appear as squiggly and string-like structures. The structures are observed under a compound microscope at a magnification of 200x, 400x, 600x. The contamination structures have an irregular and jagged appearance.

To address the contamination issue, one possible step is to introduce antifungal agents to the medium. In microscopy, detailed structures like the contamination are commonly observed using a magnification of 100x - 400x.To address the fungal-like contamination issue in S. lycopersicum cultures, one effective step might be to introduce antifungal agents to the medium. This can be done by adding paper disks impregnated with a known fungicide to Petri plates inoculated with the mycelium. To observe detailed structures like the contamination, a microscope magnification of 100x to 400x is commonly used. Fungal contamination can often be identified through characteristic appearances under the microscope, such as squiggly and string-like structures.
