HZ11 carbohydrate utilization detection. (A) Growth of HZ11 on a marine basal culture plate with agar as the carbon source, with a transparent hydrolysis zone around the colony. (B) The growth of HZ11 on marine substrate plates containing cellulose, after being stained with 1 mg/mL Congo red solution, resulted in a transparent hydrolysis zone around the colony. (C) Growth of HZ11 on a marine-based culture plate containing soluble starch after being stained with Lugol’s iodine, with a transparent zone of hydrolysis around the colony. (D) Growth status of HZ11 using different carbohydrates or alcohols as carbon sources.
